2Pack 18-Volt Replace for Makita 18V Battery BL1860B, Replacement Batteries Compatible with Makita BL1860 BL1820 1830B 1840B 1850B, Fit with Original makita 18V Battery Chargers

They are great. Both charge in my Makita charger and fit the drill. No problem. The charge seemed to last forever. I used one battery off and on for 2 months before starting to use the other one.

I’ve had my Makita drill and impact driver for about 13 years and bought the set at a pawn shop. One of the batts wouldn’t charge anymore so I ordered these as replacements. They are bigger than the originals but fit devices and charger. The quality is nice and works well giving a long lasting use.

Bought these to go with my new Mikita battery powered snow shovel. Good price for the two batteries

I find that these batteries run down faster than batteries with the same specs that are 5 years old. I wish I could return them but it’s too late to do that. After my review the seller has offered me a full refund so I have upgraded to 4 stars for the fine customer relations.

They work! Seem to be good quality and no issues

I have been using these for a few months now and they seems to be holding up pretty good. I would buy them again when needed

Way cheaper than the originals. Haven’t had too much in the way of failures. And decent batteries for the price. Would buy again.

Probably aren't true 5ah batteries but all the same I get a good week or two out of these with heavy daily use in my impact as a general home maintenance and repair provider. Excellent value for the price. The bottom of one of my casings is cracked and overall the plastic seems a bit fragile compared to OEM but that hasn't affected the functionality or runtime at all. I'd buy these again.

the product came without original charger and delivery was too longer than the expected date which was useless to me

El producto funciona y se adapta bien a los maquita el detalle es que el amperaje de 6 me rinde igual que una original de de 3 quizá un poco más, pero su precio puede que compense esos detalles, si lo recomiendo se tardó pero llegó y cumplió.

For the price, this battery (BL1860B compatible) is very good. The main downside is that the BMS is not protected against water. I've opened the battery and I've added a layer of conformal coating (a varnish) on top of it, and now it's all good. Other than that, the BMS looks very modern. There is a sensor for temperature, a pair of mosfets to cut current and shunt resistors than allows the BMS to monitor it. So protections that are claimed are actually implemented. I didn't see any obvious circuitry for cell balancing, but I would be surprised if it wasn't there, considering everything else that is already present. The battery charges up to 21.75V (4.15V per cell). It discharged to 17.5V (3.5V per cell) before it cut off (with a somewhat high current draw). Those are very conservative numbers. I wonder if it is done to be able to use very cheap cells that would be dangerous otherwise, or just to provide a margin of safety and more longevity. Anyway, I appreciate that. I don't know if the claimed capacity is real, I have not measured it. It was absolutely fine for my use case. It is probably the capacity one would get if the cells were used over their full voltage range. It might not be what you get in practice with the conservative cut-offs that are in place. I am very happy with them so far.

Ive always had good luck with these batteries. These will be used in my new makita lawnmower. Just have to wait for snow to melt. The last two I bought were for my mikita trimmer and leaf blower and am very happy with them. Great price.

Jusqu'à date très bons produits, mais la qualité medium. À l'intérieur. Il y a des petits boules de plastiques. Qui se promettent mais ça fait trop mout? Que j'ai eu aucun de problème?
