makita 5ah batteries reviewed

Seeming to lag behind for an eternity, Makita has finally launched a 5Ah lithium-ion battery.

In our exclusive report, with bonus video and images, we'll tell you all you need to know about them, including:

  • size and weight
  • performance
  • charge time
  • compatability

We asked Makita's Ray to tell us all you all about what to expect from the 5Ah 18v packs. Watch the video here:

The battery itself is the BL1850, and as you can see, it looks exactly the same as the 3Ah and 4Ah packs that preceded it.

What Size and Weight is the Makita 5Ah Battery?

The good news, among may snippets of good news, is that while it holds loads more charge it's the same weight as the 3 and 4Ah batteries, and it retains exactly the same form factor.

That means you'll get more charge for your cordless Makita tool without adding any weight or bulk.

What Runtime Can I Expect from Makita's 5Ah li-ion Batteries?

Clearly any battery that holds more charge should give you longer runtime. And that's the case with these batteries. On a like-for-like basis, the 5Ah will give you 66% more runtime than the 3Ah battery.

Quite simply, for those jobs you do over and over again, you'll be able to do even more without putting the battery anywhere near your charger.

What's the Charge Time for the Makita 5Ah?

Makita, while taking longer to release larger capacity li-ion 18v batteries, has succeeded in keeping the charge times to a minimum. Built into the battery, charger and tool is a smart system that monitors the health of the cells in the battery, meaning that it'll draw charge quickly and efficiently.

In real world terms, the 5Ah packs will charge on the standard Makita XR charger in only 45 minutes, putting it ahead of its competitors who offer similar capacity li-ion batteries.

Great news! This means you'll be able to fully charge your 5Ah packs over lunch...

The launch of the 5Ah 18v LXT packs marks a significant shift for Makita, seeming as they were to be stubbornly relying on 3Ah for the longest time. But now they've joined the 5Ah party we can't wait to hear what you think of them, and how they're positively affecting how you get your work done.

We've already had our hands on two new 5Ah equipped Makita products; the DLX2040TJ (click to see more) and the amazing DHP481RTJ brushless combi-drill (click to see more). Check them out!

The proper term that is used to compare battery capacities is "Amp Hour". When anyone says "Amp", it gives the impression of a lack of understanding.

ive also used copies and had them last for 2years at half the price.. so it turns out pretty even really. it all depends on the cells inside the battery.

im due to replace my makita batteries. had the 3amp ones since 2011 roughly. think 4 yrs heavy use is pretty good?

The extra power is absolutely fine, as long as your tool is capable of taking the 5Ah batteries they are fine. With the Makita 18V li-ion batteries the Ah is more about the runtime rather than the power.

I own a lot of the cordless makita gear and have 21 of the 3 amp batteries, 4 of the 4 amp and 2 of the 5 amp. Im alittle concerned when i use my 5 amp on my tools because theres a lot more power. Does anyone know if this can damage the motor on any of them. For example my blower has twice the power with the 5 amp and im concerned im pushing the motor too hard. Thanks for any feedback.

disaster run with Makita batteries, got angry, tried the fakes, no better. dying just outside warranty with light use. maybe 6 all up, and didn't honour warranty on one that was in warranty because of date stamp on it or something, too hard to argue. apparently widespread problem. maybe the chain saw or angle grinder was killing them or charger ?. went over to bosch, far better batteries, and most tools have a nicer feel, but not the range of equipment, so have bought a couple more makitas, but petrified of frying more batteries.

I have replaced 4 batteries in 2 years but I carry 7 3ah in total and have 11 tools to operate I have no real site power except a charging point so am now reliant on these. They seem a bit hit and miss with dependency and am quietly switching to the stronger cheaper bosch cool pack when I can afford to.

This is a very good point. We sell a lot of Makita batteries but we know they are mainly not to replace faulty genuine batteries. They are either to replace faulty fake ones or to add extra batteries to kits. Thanks for the feedback

I got 2 batteries over 3 years ago and theyre only just starting to fade..I`m a chippy too-so I would imagine my batteries are getting used just as much as yours need to change your supplier-he might not have given you genuine Makita..lot of copies out there mate ;)

Batteries will prob die within 6 months like usual makita crap batteries. I'm a makita fan, got all makita gear but batteries are absolute rubbish.
