Power Tool Battery: Choosing & Maintenance Tips

Hey, tool lovers! Do you feel a bit crazy every time you need to change the battery for your power tools? After all, there are so many different types of batteries on the market, each with its own advantages. Don’t worry, today we will help you figure out how to choose the battery that best matches your power tool, and we’ll also give you some super practical daily use and maintenance tips (make sure to read to the end~).

Types of Power Tool Batteries

First of all, there are three types of most common power tool batteries on the market, which are:

nickel-cadmium batteries (Ni-Cd)

First off, cadmium is one of the most toxic elements on Earth, and if ingested or inhaled, it can cause serious health problems. So, let’s exclude nickel-cadmium batteries right away.

nickel-metal hydride batteries (Ni-MH)

Ni-MH batteries have higher energy density and lower toxicity levels compared to nickel-cadmium batteries. Although Ni-MH batteries have made significant technological advancements, their various indicators are still inferior to lithium-ion batteries.

lithium-ion batteries (Li-ion).

lithium-ion batteries are now the “hottest newcomers” in the battery industry. Why? Because they have higher energy density, longer life, and are particularly environmentally friendly. Imagine a battery that is lighter than a lead-acid battery, charges quickly, and has no memory effect. Isn’t that great?

The following is the test data of power tool batteries given by the laboratory:

project	Nickel-cadmium battery (Ni-Cd)	nickel-metal hydride batteries (Ni-MH)	lithium-ion batteries (Li-ion)
Rated voltage	1.2V	1.2V	3.6V
Voltage operating range	1.0-1.4V	1.0-1.4V	2.7-4.2V
Specific energy by weight (wh/kg)	60	107	158
Energy density (w.h/L)	200	228	430
Deep cycle life (times)	500	500	3000
Charging temperature	0-45℃	0-45℃	0-45℃

How to Choose the Right Tool Battery

When choosing a power tool battery, the easiest way is to start with the original battery model, voltage, and capacity of your tool. By identifying these details, you can easily find a replacement battery.

You have several options for purchasing a replacement: you could visit a local supermarket, but prices tend to be higher due to additional costs like store rent, utilities, and labor. These costs are typically passed on to consumers.

Alternatively, shopping online offers more competitive prices. You can find power tool batteries on platforms like Amazon or specialized websites, but the best option is to contact us directly. We operate our own manufacturing facility, which allows us to offer power tool batteries that match the quality and specifications of the original, official models.

Our company specializes in a wide range of power tool batteries, including those for vacuum cleaners, garden tools, metal cutting tools, grinders, and assembly tools, as well as matching battery chargers and custom-designed adapters.

We offer lithium batteries for a wide range of top brands, including MILWAUKEE, DEWALT, MAKITA, and AEG. If you’re looking for more affordable options, we also carry batteries for well-known second-tier brands like HITACHI, RYOBI, BOSCH, and Craftsman, along with third-tier brands like BLACK+DECKER and PORTER CABLE. With hundreds of models available for each brand, we ensure our batteries are fully compatible with a wide range of power tools.

In addition to power tools, we also offer lithium batteries for vacuum cleaners from leading brands like Dyson, iRobot, Hoover, Shark, and Xiaomi. For your garden tools, we’ve got batteries for popular models from GreenWorks, Snow Joe, and RYOBI, among others.

Daily Use and Maintenance Suggestions

Now that you’ve chosen the lithium ion battery, the next step is to use and maintain it. Here are some must-read tips:

1. Avoid Over-Discharge: Just like you can’t run a marathon on an empty stomach, the battery will be “tired” if discharged to a voltage below the safe level. So remember to keep the battery at a certain level when not in use.
2. Correct Charging: The charger cannot be used indiscriminately. Choose the right matching charger. Although lithium-ion batteries are good, avoid overcharging, just like we can’t overeat.
3. Storage Environment: Batteries also have a “comfort zone.” Dry and cool are their favorite storage environments, avoiding high temperatures and humidity.
4. Regular Inspection: Occasionally give the battery a “physical examination” to check the power and appearance, and deal with any problems in time, so it can always be “healthy and long-lived.”
