is this the battery for the Makita LXFD01CW drill?

Asked by: RHDH
LXFD01 is the Model of the Drill. The drill works fine the batteries are dead. And the charger is not broken. The batteries were designed to stop taking a charge after a set period of time or charges.

18-Volt Compact Lithium-Ion 1.5Ah Battery is rated 3.5 out of 5 by 28.
Rated 4 out of 5 by from Not too bad... First this ad doesn't say this is the 1.5 Ampere Hour battery, which is pretty basic- HD has trouble getting the details right on their website. Second, the on-line price elsewhere is 20% less, w/ free shipping. Third, I had a couple of the early 3.0AH ones go bad- Makita may have improved them by now, All this having been said, the Makita 18V Li-ion system is great- batteries charge quickly, don't run down even after sitting several weeks, which NiCads do. The tools are very well designed, excellent ergonomics, good value for the price. They're a generation out of date, but they're still the equal of anything on the market. I bought an extra impact driver, just in case the first failed- as a professional, I don't want to be without one.

Rated 5 out of 5 by from Amazing performance! These batteries are amazing! I have been using these batteries in my cabinetry shop for a good 3 years and have not had one problem with them. It's amazing how long they last for how quick they charge. Worth every penny.

Rated 4 out of 5 by from it's a replacement battery If you own a Makita compact lithium ion drill and your battery went bad, this is your only option. I put my tools through he!!. These batteries last for about a year of regular use(making holes in duct, sinking screws, falling off ladders, etc...) 50 hrs/wk 51 weeks out of the year. Then i just get an error code and the battery won't even take a partial charge. The guys running Dewalts replace theirs at about the same rate. I'm going to try the Ryobi +one kit next time around. See how it holds up.

Rated 1 out of 5 by from Battery doesn't last I had two batteries that bought with the drill. I used my drill about once a month and after a year, both batteries won't accept a charge. I have to buy a new battery because I paid 300 for drill, charger and two batteries.

Rated 1 out of 5 by from Unhappy with this product Similar to many of the other costumers who have written reviews I, too, am having trouble with the battery. I have only had the drill a little over a year and the battery pack is flashing red and green. From what I have read that indicates that it is no longer accepting a charge! This makes me very unhappy considering the new battery will cost over 80 dollars! I am not going to put more money into a battery and product that is likely to fail in another year!I read that Makita will not do anything if it is over the year warranty. Shame on them for not standing by thier products. I will not buy another Makita drill! I had a Dewalt for almost 10 years. That battery and drill was strong during that whole time. Looks like I will go back to Dewalt.

Rated 5 out of 5 by from Fantastic product I work as a professional auto mechanic and have the drill and impact driver, and make use of the impact driver daily. The batteries lasted 8 years of daily heavy use before the plastic casing on the batteries finally came apart from stress cracks due to rough use. I highly recommend these, never experienced any issues, and most people who seem to complain about the batterys dying only use the tools a few hours each month. No battery will last like that.

Rated 4 out of 5 by from It is what it is... it's a battery. We had purchased the drill and needed a second battery to swap out with. The unit gets used off and on about 80 hours per week. The batteries charge quick and are adequate enough to keep us going with several changes throughout the day. We have had the drill and batteries a couple of months now and all seems to be well. There does not seem to be any decline in performance. The beauty of these are that they are so light weight in comparison to the De-Walt 18V drill/battery we were using. I do not feel they have the torque and power of the De-Walt and the batteries do not seem to hold a charge for as long as the De-Walts, but for the difference in weight (with a lot of the use being above shoulders), it is well worth the effort to swap batteries more often.
