Twupixy 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

Very surprised at the performance of these batteries. I bought them for a Ryobi stick vacuum. They last a very long time compared to some old makita batteries I have that are worn out. I bought some other off brand batteries which are terrible. This product was very surprising in how long it works per charge. Very happy.

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.

Apparently Great replacement for my equipment at a Great Price!

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.

My makita collection needed more battery’s These are a good buy

These batteries worked perfectly in all my Mak*ta tools. The 6Ah rating I believe is hogwash but don’t really care. They perform as well as my 3 Ah original equipment batteries and are about the same size and weight. I have only two charge cycles on them so can’t speak to the longevity. For the price I would definitely buy again.

Bought these batteries before. There very good in quality and last every bit of 6-8 hours depending severity of use. Delivery was quick. Would buy again from this seller. Highly recommend!!!

Good replacement for factory battery. Charge time and build quality are very good. the batteries discharge quicker than the original equipment manufacture (OEM) batteries.

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.

Works great

Look great seems to hold a charge and priced reasonabl
