WAITLEY 18V 5.0Ah Replacement Battery For Makita Lithium-Ion Power Tools - Compatible With BL1830, BL1840, BL1850B, BL1860 Models - LED Indicator Included Review

I was able to drain this battery in one day of installing mounts onto a roof, approximately 600 3/8" x 1.5" self tapping screws through metal and wood. While driving a screw under full power, the battery briefly dipped in power and showed 0%, then recovered back to 30% battery life remaining. I didn't use it further as I had a 6ah battery ready for the last few dozen screws. Its wise to charge these Li-Ion battery packs at 20% remaining or more for longer life, and to avoid overcharging and…

The battery it self last a lots,I gave only 3 stars because on my case is hard to put on and take it of,you really need to force it

Very good battery, better than Makita original. It does not fit the charger exactly, but still fully functional. It does last longer than original battery. So if need be, I will buy again.

It works. Plenty of power and runs my tools. The case material does not seem as strong as the OEM batteries but for the money I would buy these over OEM batteries. I have not opened it open to look at the cells or construction but it seems to work just fine. I will order another one soon as I have another OEM battery that is about dead.

I don't use it often but after only the second charge in 9-months, the charger is giving a battery error. Other batteries charge fine on this same charger. The indicator show that it only charges up to 8% before getting an error abut battery failure.The support and return window is very short.I do not recommend this battery or the provider because of the failure and the very limited life. For the price, this should not be a disposable battery. The original batteries have lasted 8-years. This…

This battery appears to be of great quality. I’ll update it if/when the 18650 cells failUpdated:The battery failed. But Waitley was great and replaced it no problem.

This is a replacement for the original battery that came with my drill and impact, it last much longer than the original batteries. Very pleased with this purchase.

Did not fit into Makits tools well. Did not last long. Will not charge on makita charging base. Waste of money. That's my review.

Charged in my 12 year old Makita charger. Have 9, 3ah brand name batteries. Maybe it's because I've been using those old ones for so may years, but this new replacement it a beast. Put it on brush type recip saw and trimmed limbs for 2 hours with no loss in power. I'll update in a few months. 20 july, 2019

We bought two of these so we could work a bit longer in the yard. These batteries work for about 20-30 minutes and power the blower very well.

Battery blew up while using it with my Makita grinder. Blew out on both sides of the battery. Glad it didn’t go when on the charger in my garage, could have had a house fire.Don’t recommend buying, only used it a few times before it blew up.

The battery works, I have used it for 2 charge cycles so far. My only and main complaint is the fit is terrible. Its a PAIN to get connected or disconnected on all 3 tools I have and the original charger as they don't line up right. Also the release button seems to be poorly made and doesn't work right either. That being said, its less than 1/2 the price of the Makita brand one so I didn't think it would be perfect but other brands fit are way better.

Incredible generic battery, I build country furniture and I’m on my second year on these batteries and they hold up really well. Have not had a single issue with these and have bought several more. Definitely a good buy On a Fantastic battery!

You could purchase real Makita batteries ( https://amzn.to/2XTWI77 ), but they are pretty expensive.I used a Electronic load tester ( https://amzn.to/2XW3WY9 ) and put a 10A load on the battery.I got 3.84Ah or 59.9Wh out of the battery (a small tool like the LXFD01Update: 4/28/2020The battery has died. I took it apart and found 8 of the 10 18650 cells had died (the cells are pink no-name brand listed at 3.7V and 7.4Wh). The scary part is that there are NO balance leads on these batteries! This…

Complete waste. Battery charged a few times (2) and then errors out and won't charge. Impossible to contact company regarding warranty, which by the way, is very short. Many other similar reviews will attest that the batteries are terrible. Do not buy.

4 stars because it had to be forced on to the green charger, tight fit on a black charger. Works great otherwise. Lasts as long as the original battery.
