Can I use this 18v battery in a 24v tool?

I have a 24v tool and i want to upgrade my battery to a Lithium-Ion.
Asked by: Vlas
I'm assuming you mean a 24v Makita tool? The battery is a similar profile and design to the 24v MakStar battery, but the connections are likely very different. Even if it did fit your 24v tool, you won't get full power to the tool- it basically would just be a heavy 18v tool. Your best bet is to "bite the bullet" and just get into the 18V LXT platform. There's a not more options than the 24v platform, the weight is incredible, and in many of the tools, the 18v LXT performs just as well, even better, than the 24V stuff!

Rated 1 out of 5 by from The infamous intentional defective Makita chip which turns their batteries into paperweights. I bought a new Makita drill / impact driver set two years ago (already owned other Makita tools as well). Both batteries supplied died. Thought that was their average lifespan. So I bought a pair of these batteries at Home Depot. I use mine Mon - Sat on job sites. I always go through two full batteries a day. After four months the first one died. I sent it in to Makita. They will not warranty it. Two months later the second one would not recharge. Dead. Sent that in to Makita, again, they refused to warranty. Now I buy the generic batteries on ebay and amazon. Then I did digging around... Makita has an intentional design flaw which causes your battery to become a brick. Google it! Unbelievable. I am dumping my Makita tools and going with something else. By the way, Makita tools are not very good. I've had plastic parts fall off and overheating and misalignments. Stapler which does not take staples they claim. So many more disasters. Where did they go wrong? I do not drop my tools. All are carefully taken care of and never loaned to anyone! They are my paycheck!

Rated 5 out of 5 by from Treat 'em right and they'll last for years! I've been using Makita's LXT lithium ion tools and batteries for several years, and I'm convinced there isn't a better option. I love the fact that they've been on the same platform for the better part of a decade, and have been making steady improvements to the batteries from day 1. Apparently unlike a lot of users and reviewers, I took the time to study information out there regarding the best way to take care of ANY Li-Ion battery, and this extra effort has paid off, in terms of less down-time, lower battery costs (by not having to replace batteries nearly as often), and Makita's fast 30-minute charge-time. The first thing with any Li-Ion battery is to not run them down to nothing. Doing this is akin to deep-cycling a car battery. Once or twice, no big deal, but doing it often will kill a battery cell, and the battery itself. If you listen to the tool, it will start to slow down when there's about 10% juice left. This is the best time to charge it. When my Makita rep told me this, I didn't really think It'd make a difference. It has truly saved me batteries, I guarantee you. Second, heat kills batteries--any battery. Even with the fan in the charger heat, whether from the weather or from heavy use, will kill a battery. I would recommend getting a third battery, that way you have one being used on the tool, one cooling down after being used, and a cooled battery charging up on the charger. This little move not only saves the battery over time, since the charger isn't working as hard, it will charge a little bit faster. Third, when storing batteries, it's best to have them with some moderate level of charge on them: not empty or fully charged. I use mine pretty much year-round, so I don't have a lot of down time with mine. Fourth, try to take the battery off of the charger once it's done charging. The LXT charger is pretty advanced, but it's still best to get the battery off of the charger to prevent any over-charging. I'm not saying run to the charger once it's done, but don't leave a charged battery on a charger for hours. There are a lot more on-line tips and suggestions you can find, so I won't put them all on here. All the tool brands will claim they have the best batteries out there. One thing you have to ask yourself, is if they're so good, why are they coming out with "all-new" batteries every 2-3 years? Makita has been steadily improvign these LXT batteries for almost 8 years, because they were the best to begin with. When they find areas to make them better, they do so! Don't waste your time and money buying the red, yellow, or orange flavor of the week batteries.

Rated 1 out of 5 by from Battery dies after ten charges. Do not buy! Battery was charged about 10 times. Gave good power for the first ten, then out of the blue it gave me that red beeping alarm on the charger. This is due to their internal chip that shuts down the charging for some random reason - not for the number of cycles. These batteries are expensive and are defective!! Look for another brand. Home Depot should not sell these and Makita should offer a refund or a recall. My battery is now of no use and new ones are $99. Home Depot sold it to me as a sale item but now I wont buy one again at Home Depot and I wont buy another Makita!

Rated 1 out of 5 by from Battery failure too high Two batteries failed to charge within one year. First one I had replaced under warrantee. Second battery still ran fine (until totally discharged) but got red light of death from two different charges. I fill like the problem is in the control chip, not the batteries them self. Afraid of a fire lawsuit, Makita has programed the chip to shutdown way to easily. Searching the web will yield you volumes of charging failures.
