    • Seems to work well.

    • 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.

    • Working fine in my wireless headphones. Saved me the cost of new bluetooth phones!
Style: 503035 500mAh
Perfect fit for my wireless noise-cancelling headphone repair! Working reliably for six months and take a charge. I do not ever let my batteries go down to zero charge (to preserve their life) but I would say they easily last 6-7 hours (our last flight from the west to eastern seaboard.) Yes, some soldering was required because I didn't have a plug, but I made sure the size, amperage, and amp-hour was correct. Make sure the capacity numbers match up. ... show more

    • Doesn't Hold A Charge
Style: 692245 750mAh
This battery has identical specs to the one that came with my small soap dispenser. However, the one a received doesn't hold a charge for more than a week of infrequent use. The brand that I replaced would hold a charge for three months. I would not purchase this product if you plan on recharging it. ... show more

    • This Item Works Flawlessly!!!

This item made my day. I needed to replace the battery in my Lenovo ThinkPlus TH30 headphones. This item works very, very well. This battery holds a charge as it is intended to do. I am so happy with this item's performance. Oh yeah!!!

    • Warning - wires may be reversed!
Style: 955178 4500mAh
Review Image by Army of One Army of One
Be very careful. This almost destroyed my eInk screen. I just received one of these, however the positive(+) and negative (-) wires were reversed on the JST connector from the battery. As soon as I connected this to an eInk screen, I could smell but did not see the magic smoke and immediately disconnected. I then inspected the wires and double checked JST wiring convention with other devices using the same size/type connector. They were all working and reverse of the wires on this battery. Very Dangerous and I doubt this company would refund the replacement costs of a destroyed device. ... show more
