What is a Power Tool Battery?

A power tool battery is a rechargeable battery designed to provide power to electric power tools. These batteries are typically lithium-ion (Li-ion) or nickel-cadmium (NiCd) types, which are known for their high energy density, long lifespan, and ability to hold a charge for extended periods.

Know Your Power Tool Battery

Understanding common concepts and features of power tool battery can help you choose the right battery for your tool and different applications. Here are some important terms to know:

Voltage
Voltage refers to the battery's strength and determines the power level a tool provides. Always consider the voltage requirements of the specific tools you plan to use. Tools with higher voltage batteries are more powerful, which is important when performing heavy-duty tasks, but they may be heavier and less compact. Tools with lower voltage batteries are often lighter and more compact but less powerful. Matching the voltage of the replacement battery to the original tool ensures that the tool will operate at its intended power level.

Battery Capacity
Measured in amp-hours (Ah), the capacity refers to how much power a battery can hold and how long it can run before recharging. Certain tools require higher Ah to operate to user expectations. When comparing batteries, look at the Ah ratings to determine a battery’s overall storage capacity and run time. Higher Ah ratings mean the battery can be used for longer periods before needing to be recharged. However, as Ah ratings increase, so does the weight and bulk of the battery and hence the tool.

Memory Effect
This phenomenon occurs in older battery chemistries, like NiCd, where the battery remembers its previous capacity when it's not fully discharged before recharging. When memory effect happens, the capacity can gradually decrease, reducing overall battery life. Newer lithium-ion batteries don't have a memory effect, making them potentially longer-lasting.

Types of Power Tool Battery

Nickel-Cadmium (NiCd)	Nickel-Metal Hybride (NiMH)	Lithium-ion (Li-ion)
NiCd power tool batteries are what we might refer to as 'older generation' batteries. NiCd batteries are generally heavier and take longer to charge.	Much lighter than their NiCd counterparts, NiMH batteries are often used to replace older NiCd batteries. NiMH batteries are, however, sensitve to self-discharge and deterioration linked to memory effect.	Li-ion technology is a much more recent development and li-ion batteries are nowadays used in a wide range of devices. Li-ion technology offers a wide range of advantages, including long operating time, light weight and durability - the perfect technology for your power tool battery.
Pros: Quick, easy charging Long life expectancy	Pros: Higher capacity than NiCd Weaker memory effect than NiCd Less polluting than NiCd	Pros: In general, higher capacity than NiMH Low self-discharge No memory effect Lightweight Built-in protection circuit
Cons: High self-discharge Memory effect Polluting (cadmium)	Cons: Self-discharge Memory effect	Cons: More expensive Sensitive to deep discharges Difficulty balancing voltage - requires a PCM (Protection Circuit Module

Main Causes of Memory Effect:

●When a battery is discharged repeatedly to exactly the same level, and then recharged.

●When a battery gets old.

●When a battery is charged too slowly.

●When a battery is exposed to high temperatures.

●When a battery is completely discharged (batteries should be discharged until the point where the tool refuses to function adequately).

●The most common reason is when a battery is persistently overcharged (voltage depression).

Volts and Battery Power

One of the most prominent specifications you’ll see on a power tool or a battery is the voltage. The voltage of a battery, noted as volts (V), indicates the energy or power a battery can provide to a tool. More volts gives the tool more power. For example, a 24-volt battery can provide higher torque or rotational force to a drill, allowing it to bore into dense material quicker than a 12-volt model. Higher-voltage battery packs have more individual battery cells built in. More cells provide more power, but they also add weight, so the 24-volt battery will be heavier than a 12-volt battery of the same type.

How many volts do you need in a battery? It depends on the work you need to do. For general maintenance and repair work, a 12- or 20-volt tool and battery will suffice. They’ll handle the most-common tasks a homeowner might take on and will be lighter and more economical than a 24-volt or higher tool and battery combination. However, heavy-duty projects (such as building a deck or installing a fence) can benefit from the higher-voltage tools and batteries, so if you plan to take on large projects, the added weight might be worth it.

Amp-Hour Ratings and Battery Runtimes

In addition to volts, look for the battery’s amp-hour rating (ampere-hour rating). The amp-hour rating (Ah) of a battery will be noted in the product information and may be printed on the battery along with the voltage. What does Ah mean? An amp-hour measures battery capacity or how much electrical current a fully charged battery can provide over a period of 60 minutes. While the actual time the battery can operate a tool varies by the level of current the tool needs to function, a higher amp-hour rating means a battery can operate the tool for a longer period of time.

Higher amp-hour batteries also allow a tool to use more of its available power to complete a job faster and can better maintain the power level. While the constant power level doesn’t benefit light-duty work significantly, higher-rated batteries are more effective for heavy-duty jobs, letting you complete the work more efficiently.

The battery amperage-hour rating you should look for depends on how you’ll use the tool it powers. As with voltage, you can handle a few light jobs effectively with a battery that has a lower rating. If you have a lot of heavier work to do, a higher amp-hour battery will more effective. It’ll weigh more, but will complete the job noticeably faster.

Features to Consider in a Power Tool Battery

Volts and Battery Power

This is the most important aspect of any power tool battery. You can choose the best manufacturer of power tools. But if you pair it with their lowest quality battery, you’re going to be left wishing you had chosen differently.
The basic rule is that more power is better. That’s why you need to look at the volts. The most modern power tools are rated at 18V or 20V but it should be noted that some tools require more power. This is a good option if you only use the high-powered tool occasionally, you can simply borrow the battery from other electric tools.

Amp-hour Ratings and Battery Runtimes

As mentioned, the higher the amp the longer the runtime of the battery. In most cases, this makes buying higher amp batteries the most logical choice. Of course, higher amp batteries are more expensive, larger, and heavier. You’ll need to consider this when choosing a battery.

5 Tips for Maximizing the Life of Power Tool Battery

Use the Right Battery and Charging System
Choosing a low-power battery, like a 2.0 Ah or 4.0 Ah, for a high-powered tool often requires frequent recharging and can decrease the battery’s life span. Pick a charger or charging mode suitable to the application and run time needs.

According to Power Tool Institute, original manufacturer batteries contain innovative technology to monitor battery health, cell balance, temperature and other critical functions designed to help maintain longer-lasting tools. Only tools, batteries and chargers from the same manufacturer are designed to work together. Since each manufacturer has unique circuity designs, aftermarket or counterfeit batteries may not include all the safety design features or undergo the same testing and quality controls as manufacturer batteries. This could lead to damage, fire or injury. Further, note that it can be challenging to visually determine aftermarket and counterfeit batteries.

Avoid Extreme Temperatures
When using or storing lithium-ion batteries, try to avoid high and low temperatures. Temperatures over 175 F can cause permanent damage to the battery. While that temperature may seem high, factors such as being in direct sunlight or inside a hot trunk can quickly cross that temperature threshold. According to University of Michigan researchers, “elevated temperatures can accelerate the degradation of almost every battery component and lead to significant safety risks, including fire or explosion.” Experts recommend storing batteries in air-conditioned spaces whenever possible since the optimal temperature is around 59 F, with most battery chemistries having an extreme temperature threshold ranging from minus-40 F to 122 F.

Properly Store Batteries
Storing power tools in a moist climate can cause corrosion or lead to problems with the electrical components. Tools should be stored inside a case or cabinet to help eliminate dust and other particles from entering the vents when not in use. Securing them in a toolbox with foam inserts or using a battery holder can also help protect your tools and prolong battery life. Always store your power tools in a cool, dry place since keeping batteries near the optimal temperature mentioned above can help extend run time and make the charging process more efficient.

Use Power Tools Regularly
Batteries have a life expectancy and deteriorate when not in use. When a battery isn’t used immediately after charging, it will slowly lose its charge. Some battery technologies have a faster self-discharge rate than others. For example, if NiCd batteries are stored outside the charger, they will naturally begin to discharge, losing the bulk of their capacity in the first three days. However, lithium-ion batteries have very minimal discharge rates when not in use. Once a battery is damaged, it often has to be recharged more frequently. Recharging battery packs creates more heat that can damage the battery further. Keeping a spare battery ensures you always have a charged battery ready.

Protect Batteries from Liquids and Metals
Avoiding moisture may sound like a no-brainer, but jobsites are prone to all types of weather, so that’s not always possible. Some battery packs are designed to help direct water away from internal electronic components. It’s important to store your power tool batteries where they won’t be exposed to water, liquids or make contact with metal objects such as keys, coins, screws or nails, which can present safety hazards.

7 Tips for Choosing Your Power Tool Battery

●Ideally, you should choose a tool that comes with two batteries so you don't get caught out when you're working on a longer task (you can simply swap the batteries over).

●Lithium-ion batteries are lightweight and will therefore make your tool easier to handle.

●If you have the choice when replacing an old battery, go for a battery with a higher ampere hour rating so it lasts longer between charges.

●Be sure to purchase a battery with the same voltage as your power tool so as not to damage your equipment.

●You can choose to repair an old battery in which case the components will be replaced; beware that the costs of delivery may be high. It's a good idea to ask for a quote to avoid any unpleasant surprises!

●A battery indicator will be a handy and provide you with more control in terms of recharging.

●Do not store your batteries without charging them first. If you don't plan to use your tool for a while, be sure to charge it fully before storing.

FAQ

Q: Is a higher Ah battery better?

A: In general, the answer to the question “is a higher battery better?” is yes. However, if you’re going to work in tight spaces or the weight of the cordless tool is a concern, you may find that the smaller and lighter low amp batteries are a better option. The disadvantage is that you’ll probably need two or three of them to ensure you can always use your tool.

Q: What type of batteries are used in power tools?

A: Almost all power tools now use lithium-ion batteries, referred to as Li-ion. This is more expensive than the older batteries, which were either nickel and cadmium or nickel and a metal hybrid. Furthermore, Li-ion batteries are more durable and will provide the same level of power until they are empty. On the other hand, nickel-based batteries tend to lose power and cause your tool to work slower as the battery loses power. Li-ion batteries can be found in a vast array of voltages, from 12-36V and the amps can be as little as 1.2Ah or as high as 9Ah.

Q: What are the best rechargeable batteries for power tools?

A: As previously mentioned, Li-ion batteries are the most common option in modern power tools. You may be asking yourself: “are lithium batteries better for power tools?”. The simple answer is yes.

Q: Can I charge an 18V battery with a 20V charger?

A: Yes, it is possible, as the electronics, motors and cells are better. However, the voltage delivered is exactly the same as an 18 V tool.

Q: How do you bring a power tool battery back to life?

A: First, you have to insert the discharged battery into the tool's charger to see if it starts charging. If so, leave it on charge for one hour or until the process is fully completed. If it does not charge, repeat the starting procedure, but this time leave it plugged into the tool's charger for 10 to 12 seconds.

Q: What is the best way to store power tool batteries?

A: To store batteries at their best and keep them at peak performance, the following tips should be observed.
Store and charge batteries in a cool, dry place.
Avoid exposing batteries to liquids, oils or extreme temperatures.
Clean batteries with a clean, slightly damp cloth. It is strongly discouraged to clean them using solvents.

Q: How to store your batteries?

A: Make sure batteries aren’t subjected to extremes of heat. Ideally you should keep them at room temperature as heat is one of the main reasons Li-Ion battery life depletes. So avoid leaving power tools in the car or van if they're going to be out in the sun for a long time. Equally freezing conditions can reduce the lifespan of the battery - something to remember on those long winter nights.

Q: You should fully discharge Li-Ion Batteries in order to maintain capacity?

A: False. While it’s true that NiCd and NiMh batteries need to be fully discharged to keep their optimum condition. The opposite is true for Lithium-Ion batteries which should NOT be left to fully discharge. This can actually damage the battery. Li-Ion also doesn’t suffer from Memory Effect and so can you can charge these at any point.

Q: How to choose a power tool charger?

A: Choosing a suitable power tool charger is important if you want to get the most out of your power tool. The advice below will help you choose a suitable cordless tool charger:
Voltage: the power tool charger must be compatible with the voltage of your battery.
Charge current: control the speed at which you power tool battery is charged. The higher the charge current, the quicker your battery will be recharged.
Technology: Make sure the charger is compatible with the technology of your new power tool battery as many older chargers are only compatible with NiCd batteries. You may need to buy a replacement battery charger.
Brand: whether you are looking for a genuine battery from the original manufacturer or a high-quality compatible battery, you will need to know he brand of your power tool.

Q: How long do power tool batteries last?

A: A battery’s cycle life indicates how many times it can be recharged before it needs to be replaced. NiCad batteries typically have a greater cycle life than li-ion batteries but lose power if not maintained properly. Amp-hours indicate how long a battery can power a tool before needing a recharge. Li-ion batteries offer higher amp-hour ranges.

Q: What is memory effect and how does it impact how my battery charges?

A: Older power tools containing nickel-cadmium (NiCad) and nickel-metal hydride (NiMH) batteries can develop memory effect. Memory effect occurs when a battery remembers how much charge was drained before being charged, so it changes its capacity to a lesser charge. This happens when a battery is constantly partly drained and charged without fully discharging first. For this reason, you want to allow NiCad and NiMH batteries to dissipate fully before recharging them to avoid developing a battery memory. Lithium-ion batteries do not have a battery memory, so recharging is recommended after each use to ensure your batteries are fully charged when you need them.

Q: Can I leave my battery on the charger?

A: In most instances, the answer is no. Keeping your battery on the charger makes it challenging to ensure battery safety and can cause the self-discharge rate to get worse. However, it ultimately depends on the tool and the type of battery you have. Many newer chargers allow you to safely leave the batteries on chargers. If the manufacturer doesn’t recommend keeping the battery connected, it is best to disconnect and store it according to manufacturer guidelines.

Q: How long can a lithium-ion battery last before it needs to be replaced?

A: Li-ion cordless tool batteries typically feature a 300-500 cycle life, which is around 2-3 years. Cycle life indicates how often a battery can be charged before losing its ability to retain a charge. Therefore, you can generally charge a Li-Ion battery at least 300 times before it needs to be replaced. However, the amount of charging cycles you can get from a battery depends on several factors, including battery configuration, capacity and storage conditions.

Q: What is the most common power tool battery?

A: Lithium-ion batteries are the most popular batteries due to their high energy capacity, weight and faster charging capabilities.

Q: How do I know which battery is more powerful?

A: A higher voltage battery has the potential to "push" more current--that is, more electrons--for a given resistance. This translates to the capacity for greater work, which is the same thing as more power. Higher voltage also means less current to do the same amount of work, so longer battery life.
