Which makita replacement battery is best?

A good replacement battery or two can keep your productivity levels high and breathe new life into an old Makita power tool. Makita has been at the forefront of cordless power tool technology for decades now, and is known for engineering and manufacturing durable, high performance products. Whether you’re an occasional fixer or professional tradesperson, you may very well have a Makita tool in your kit. 

However, sifting through pages of technical specifications and terminology to find the right one is taxing. Continue reading to learn more about what to consider when buying a replacement battery. If you’re looking for a top-of-the-line battery that you can rely on to work as well as your Makita tools, consider the Makita BL1850B-2 battery pack

What to know before you buy a Makita replacement battery

Battery life 

There is a significant weight difference between batteries that optimize extended use and those that don’t. If you’re worried about not being able to handle a heavy, cumbersome 5.0 Ah (ampere hour) battery consider buying two 2.0 Ah batteries so you can switch them out. However, keep in mind the fact that a 4.0 Ah will last twice as long as 2.0 Ah battery at a minimum. 

Tool compatibility 

Although Makita has an extensive line of tools that use the same battery platform there’s a chance your tools may require an older battery style. First make sure that the voltage output of the battery is the same as the tool, and then check the battery style. Your tool may have a newer slide-on battery or one of the older pod-and-stick designs. Finally, make sure that the battery chemistry on your replacement battery is the same that your tool designed to receive. Check out the full Makita replacement battery buying guide from BestReviews to learn more. 

What to look for in a quality Makita replacement battery

Power management 

There’s always a risk when using a non-branded replacement battery on a Makita tool, so make sure whichever one you choose is equipped with the same power management technology Makita offers. Quality replacement batteries will offer overload, overheat and over-discharge protection. 

Charging time 

Premium replacement batteries will charge just as fast, if not faster than your original Makita battery. Makita is not the only company on the market with rapid charging technology so you don’t have to get a Makita branded battery if you really don’t want to. Batteries with lower ampere hour capacity will charge faster. 

STAR Protection

While only Makita branded batteries will offer their unique STAR protection system, not all Makita batteries have it. The STAR computer controls allow the tool and battery to exchange data in real time to extend battery life and improve tool performance. The STAR system also helps with the built-in power management technology all Makita batteries include. 


Although this may seem counterintuitive, premium batteries should have a good amount of heft. Quality battery cells are denser, and therefore heavier than their cheaper counterparts. While you can rest easy if you spent the money for a branded replacement battery, if you purchased an off-brand replacement make sure it doesn’t feel suspiciously light. 

How much you can expect to spend on a Makita replacement battery

Replacement batteries manufactured by Makita cost around $100 while quality off-branded options can cost as little as $30. 

Makita replacement battery FAQ

How can I tell if my replacement battery is compatible? 

A. Always double check compatibility before buying replacement parts for any tool. If you’re buying an off-brand replacement check the Amazon listing or website for a list of compatible serial numbers. Cross reference this list with your tools serial number to see if they are compatible. 

What’s the difference between NiCd, NiMh and Li-ion batteries?

A. These funky acronyms refer to the different types of battery chemistry. Nickel-cadmium (NiCd) batteries are older and have limited performance. Nickel-metal hydride (NiMh) batteries are powerful, long-lasting and fast charging in comparison to their NiCd predecessors. Lithium-ion (Li-ion) batteries have the newest high performance technology on the market.
