    • Ok works
Just so you know this is 1.5 mm connections and there is no thermistor. They work but if they're in confined places you probably really want that thermistor

    • Tried to fix Bluetooth speaker…
But didn’t work. Even charged it. Not sure if it was battery or something else. Great price and condition seemed identical to what was in there.

    • Will not hold charge
I really hate the fact that this battery will not hold or even keep enough charge to fly the drone my stepson got bought for Christmas. This is the exact battery it called for to be able to be used as a replacement and now I have a disappointed kid who did not get to use their Christmas Gift.

    • Low capacity, I would not recommend and will need to replace this with something better
I bought this for my portable coffee grinder. When the grinder was new we would get maybe a dozen or so uses but as the battery aged, I was lucky to get a single grind. This battery is only a little better than the old dead one I replaced. I get 1, maybe two grinds at best for each charge. I do not recommend these batteries, they are low quality. ... show more

    • Should fit but doesn’t
This battery was to be a replacement in my EcologicMart.com book light. It looks identical to the original, has the same part number (103040) and the same 3.7V, 120-mAh specs. It fits perfectly in the battery compartment however the plug is very slightly too large to fit in the socket. Unfortunately I don’t know what to order at this time since there are a number of 103040 batteries shown on Amazon. Very disappointing. ... show more
