Rechargeable Battery 3.7 Volt Battery Flat Top, 3500mAh High Capacity Flashlight Battery for Headlamps, Doorbells, Handhold Fan, Toy 2Pack

Bought these to use baby toys in place of cell batteries.Compatible with the charger I already had and it seems to work pretty good.Hope they last longer as described but good for the money paid.

Batteries arrived packaged in a small custom plastic box with a latch. Batteries had 3.4 volts when they arrived. I installed one battery in a small Bluetooth speaker that also has many LED lights and a lazer light. Installation required soldering to the battery. Battery had no trouble being soldered. Keep in mind that I do have professional soldering equipment as well as top of the line flux and solder. After installation I charged the device to full capacity. So far the battery has performed very well. We haven't used the device for an extended period of time yet so I'm hoping that the battery continues to do well. I've been disappointed by other batteries right out of the box. Dead on arrivals. This battery hasn't disappointed me in any way so far. I have no complaints at this time and I would recommend it to others.

Accurate description, perfect replacement for solar light battery.

Long Lasting battery

Good thanks

Arrived on time and as advertised. Very well packed. I even like the color.

Used an Industry-standard charger with full readouts: voltage, power, mAh... you get the point.I charged these batteries for 12 hours. First problem: They read out as "fully charged" at 1735mAh, not 3500. Likely a mislabeling, I thought. Annoying, but pretty common, right?Second problem: I switch from "charge" to "test" mode--IMMEDIATELY back to 0mAh. I tested them again in a backup 18650 charger, same result. Zero charge.This isn't even a case of "barely holds a charge for X-minutes;" they literally cannot be charged nor hold a charge. They're totally spent. Literally repackaged e-waste. Buyer beware.

Exactly as described, arrived promptly
