Rechargeable energy storage units made expressly for portable power tools are known as power tool batteries. They offer a handy and transportable source of power, enabling the use of power tools without the need for an electrical outlet. These batteries are nickel-cadmium (NiCd) or lithium-ion (Li-ion) based. In contrast, lithium-ion batteries are more frequently employed in contemporary power tools because of their better energy density, longer runtimes, less weight, and diminished memory effect.

Everything you need to know about power tool batteries to choose the right one

Battery Types

Nickel-Cadmium batteries are durable and can handle high-drain applications. Compared to NiCd batteries, NiMH batteries have a higher energy density and don't experience the memory effect. Lithium-ion batteries offer the highest energy density, longer runtime, and no memory effect.

Voltage

Power tools typically come in different voltage ratings, such as 12V, 18V, and 20V. Higher voltage generally means more power and better performance. However, higher voltage batteries may also be heavier and bulkier. Consider the type of tasks you'll be performing. Lower voltage batteries may be sufficient for lighter tasks, while heavy-duty tasks may require higher voltage batteries.

Amp-Hour (Ah) Rating

The Ah rating indicates the battery capacity, which also establishes how long it will operate between recharges. Higher Ah ratings generally provide longer runtime. Consider the type and duration of your projects. If you frequently work on long tasks, opt for batteries with higher Ah ratings.

Compatibility

Ensure that your chosen battery is compatible with your specific power tool model. Different manufacturers may have proprietary battery designs, so check for compatibility before purchasing. Some manufacturers offer backward compatibility, allowing newer battery models to work with older tools. This can be beneficial if you own power tools from the same brand.

Brand and Quality

Choose reputable brands known for their quality and reliability. Established brands often have better customer support, warranty options, and a wider range of compatible tools and accessories. Research customer reviews and ratings to gauge the performance and durability of the batteries.

Cost

Battery prices vary significantly depending on the brand, type, and capacity. Consider your budget and the value you expect from the battery in terms of performance, durability, and runtime. Cheaper batteries may save money initially but may have shorter lifespans or lower performance, resulting in more frequent replacements.

Charging Options

Look for batteries that offer efficient charging options. Some batteries come with fast chargers, allowing you to recharge them quickly, while others may take longer. Consider whether the battery is compatible with universal chargers or if you'll need to purchase a dedicated charger separately.

Safety Features

Check for safety features like overload protection, temperature monitoring, and short circuit protection. These features help prevent damage to the battery and ensure safe operation.

Warranty and Support

Review the warranty provided by the manufacturer. Longer warranty periods indicate the manufacturer's confidence in their product. Good customer support is also essential if you encounter any issues or have questions.

Because the battery is what makes it possible for cordless tools to do their work, choosing the type of battery technology that the tool uses is almost as important as the choice of tool itself.

For example, if the battery's capacity, charge time, or storage characteristics are mismatched to the work or user, the expensive tool it's attached to might not do the user much good.

Cordless power tools are used all over, and they're becoming even more plentiful. Manufacturers release more cordless models, and more powerful models, every year. On top of that, power tool battery technology is also seeing rapid changes. This means that there are more battery options out there (and we'll probably be seeing more), and that many of those batteries are expected to do heavier work than ever before. The best thing that shoppers can do is be as informed as possible about battery designs, performance, specifications, and features to keep up with the industry. The information in this article gives cordless tool users and shoppers the head-start they need to choose the right rechargeable battery types for their cordless tools, and then get the most out of them.

Rechargeable Battery Characteristics

There are a few terms and characteristics about rechargeable batteries that shoppers should become familiar with before setting out to make a cordless power tool purchase.

Things that affect a battery's overall life and run time are usually the determining factors when power tool battery shoppers zero in on a decision (after cost of course), so most of the characteristics explained below have some influence on how long a battery will last.

cycle life-

The overall life of the battery, usually expressed as the number of charge cycles that it can withstand before completely losing its charge capacity or ability to transfer energy. For example, NiCd batteries tend to have a cycle life of 1,000 charges (cycles) or more. All rechargeable batteries eventually wear out, although they wear out for different reasons.

Age, use, and memory effect can all contribute to the inevitable death of a power tool battery, depending on the battery type.

Users often have to choose between a long cycle life and other attractive features, like run time. For example, because they can run longer between charges than other battery types, the shorter cycle life of Li-Ion batteries isn't usually a problem for users who care more about keeping their tool in operation for longer periods.

self-discharge-

All rechargeable batteries slowly lose their charge when not in use, but some batteries lose their charge much faster than others. For some users, batteries with fast self-discharge rates aren't a problem, especially if their cordless tool's see little or no storage. Batteries with a slower self-discharge rate become more important for tool users who plan to user their cordless tools only occasionally.

voltage-

Voltage determines how much power a battery can deliver at a given time. Simply, cordless tools with higher voltage are more powerful.

Rechargeable power tool batteries are usually a cluster of individual cells. The combined voltage of the cells determines the battery's overall voltage; however, different types of batteries (NiCD, NiMH, Li-Ion) have different individual battery cell voltage capacities. For example, the battery for an 18v cordless drill with a lithium battery would consist of around 4 individual Li-Ion battery cells, because Li-Ion batteries can typically deliver 3.6v-4.2v per cell. Individual cell voltage for NiCd and NiMH batteries are about 1.2v and 1.4-1.6v, respectively. Very roughly, and with some overlap, the scale for matching tool voltage to workload is like this:

Light Work: 7v-15v
Medium Work: 12v-18v
Heavy Work: 18v-36v

capacity (run time)-

This is the amount of time a battery can operate its tool between charges. A battery's capacity it usually expressed as the amount of amperage hours (Ah) that it can deliver. "Ah" is different than the tool's overall amperage rating (the current at which the tool operates). Instead, Ah represents how much energy flow the battery can hold, not the level of current during operation. When shopping for cordless tools and their batteries, just remember that a higher Ah means longer battery use between charges.

deep discharge-

Deep discharge means allowing a tool battery to completely drain of energy through normal operation. Deep discharge can be a problem for some batteries, and drastically reduce a battery's cycle life and capacity. For other battery types, deep discharge is not a problem.

Also , some batteries require deep discharge periodically to keep the battery healthy. This additional maintenance can be a hassle for users who do not use their cordless tools often.

memory effect-

Memory effect happens when a battery is charged over and over again without being allowed to fully drain. The idea is that somehow the battery "remembers" how much it is being recharged, and then adopts the shorter charge range as its new charge capacity. Interestingly (and confusingly), the nickel based batteries that are susceptible to memory effect retain their capacities best when they are charged after dropping to only 70% of their capacity. However (and this is the trick), they must be allowed to deep discharge periodically so that the battery "remembers" its true capacity.

Some rechargeable batteries are sensitive to "memory effect," and some are not.

Power Tool Battery Types

There are three major rechargeable battery technologies in use today for cordless power tools: nickle cadmium (NiCd), nickle metal hydride (NiMH), and lithium ion (Li-Ion). We describe these battery types below, list pros and cons, and offer an overview of characteristics and specifications for each.

Nickle Cadmium (NiCd)

The oldest design of the three, NiCd batteries are still in use today because they are tough, inexpensive, and have a long cycle life. Although they are still great for some jobs, NiMH and Li-Ion outperform NiCd batteries overall.

Pros:
  • NiCd batteries are more difficult to damage from heat and impact.
  • NiCd batteries have a longer cycle life of about 1,000 charges.
  • They put out strong current flow.
  • They are less easily damaged by being stored in deep discharge, although it is still not recommended.
  • They are less expensive than other rechargeable batteries.
Cons:
  • Nickel Cadmium batteries are the heaviest of the three types.
  • Lower capacity than other batteries.
  • NiCds shouldn't be allowed to drop below about 70% charge between charges, or the battery lifetime can be shortened.
  • Most NiCd batteries must be allowed to cool before being recharged.
  • Must be allowed to deep discharge about once a month or they will suffer severely from memory effect.
  • The cadmium in NiCd batteries is very damaging to the environment and must be disposed of correctly.

NiCd Battery Overview:

cycle life: long; 1000+ charge cycles

self-discharge: moderate, 15%-20%

capacity: low; 1.2 Ah - 2.2 Ah

optimal charge time: fast

maintenance: high; deep discharge once/month

memory effect: high if not maintained properly

sensitivity: very tough

Nickle Metal Hydride (NiMH)

A newer technology, NiMH batteries improve upon NiCd in several ways, including less toxicity to the environment. The biggest improvement with NiMH is their increased capacity, which can be two to three times longer than NiCd batteries. However, NiMH are also very sensitive to storing and charging conditions.

Pros:
  • NiMH batteries are a little lighter than NiCd batteries.
  • They have a higher energy density, meaning that their capacity is greater than NiCd batteries, running 2 to 3 times longer in a single charge.
  • They are less expensive than Li-Ion batteries.
  • Capacity loss can be reduced drastically if charged and stored properly, making it possible to greatly increase their cycle life.
  • They are not destructive to the environment.
Cons:
  • NiMH batteries are more sensitive to temperature, especially cold temperatures, and should only be stored or operated between about 33°F - 103°F.
  • Deep discharge and lack of use will damage NiMH batteries, shortening their lifespan and limiting their storage capacity.
  • Should usually be charged after reaching 70% capacity, but should also be allowed to deep discharge every three months to avoid memory effect.
  • They are more expensive than NiCD batteries.

NiMH Battery Overview:

cycle life: varies; can be as long as NiCd if stored and charged correctly.

self-discharge: fast; 20%-30%

capacity: moderate; 2.2 Ah - 3.0 Ah

optimal charge time: fast

maintenance: moderate; deep discharge once/three months

memory effect: moderate; can be avoided with proper charging

sensitivity: very sensitive to temperature

Lithium Ion (Li-Ion)

Lithium ion batteries (Li-Ion) are the newest technology in rechargeable batteries to be introduced to cordless power tools. They are definitely the best choice of the three types of batteries, outperforming in all areas, but they are also expensive. Heat is the biggest risk to Li-Ion batteries. Because they do not suffer from memory effect, Li-Ion batteries do not wear out over time because of charging issues. Instead, Li-Ion batteries wear out because of age and use. Regular age and use wear down the internal components of Li-Ion batteries and reverse their electrochemical processes. Heat, at any time during use or charging, is the major cause of accelerated deterioration in Li-Ion batteries.

Even with their relatively short life cycles, Li-Ion remain a better choice because of they charge fast and have a high capacity. Also, because the technology is still pretty new, Li-Ion batteries are still seeing many improvements that overcome their minor disadvantages.

Pros:
  • Li-Ion batteries are the most light-weight of the three kinds of rechargeable batteries.
  • Li-Ion batteries benefit from high energy density like NiMH batteries do.
  • They are much less sensitive to damage from temperature changes than NiMH batteries.
  • Li-Ions are not restricted in the shape of their design like NiCd and NiMH batteries are, and can be designed in almost any shape for better
