  • Will save your day
Style: 104050 2300mAh
Works great. We’ve used it several times. Small and compact. Exactly as described.

  • Good Battery, Just Make Sure You Use a BMS
Style: 503759 1200mAh
The battery works well and provides the expected 3.7 Volts output, but you definitely need a BMS (battery management system) to safely charge and recharge it. Once set up properly, it’s a solid LiPo pack for electronics projects and good value for the money.

  • Work well
Style: 803040 1000mAh
I bought this battery for my son's walkie talkie. However, the connection did not fit. My husband had to cut the connection from the old battery and remove the connection from the new battery and place the old battery's connection onto it. It worked perfectly afterwards. It was the right size and it functions well. It keeps good charge. ... show more

  • Good replacement battery.
Style: 103040 1200mAh
I used the battery to replace a defective one in a rechargeable headlamp. The headlamp didn't have a connector, but it was easy to remove the old battery and solder in the new one. The new battery was a little bit thicker than the original, but it still fit in, although a bit tight. The battery had a partial charge when delivered, and charged fully within a hour. ... show more

  • Revived a Digital Magnifier with same battery
Style: 803040 1000mAh
This was a random purchase but it ended up working! My mom had an old electronic magnifier that used this model battery and she was sad when it stopped holding a charge. I opened it up, ordered this battery, and one spicy pillow swapped out later, it must have been a perfect match for voltage, capacity, and type because her device works again and holds a nice long charge. ... show more

  • Leads assembled with polarity reversed
I'm an experienced Electronic Technician. I was rebuilding a Bluetooth Smart speaker. I knew the battery was bad. I found this replacement and installed it without checking the polarity but who checks this on a simple remove and replacement. You assume the product was quality checked prior to shipping. I installed the battery and turned it on. The unit didn't work so I knew it was a defective battery. I saw it unit powered up but just didn't function properly. I removed the battery and compared it with the old battery. See attached picture. The leads were reversed. I simply reversed the leads and the speaker powered up just fine. I'm guessing a person performing a battery replacement at this level must have a little experience with an understanding of polarity. For me this is not a big issue. Overall the price is right and I love the Prime shipping speed. ... show more
