  • 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

  • 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

  • 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

  • Unclear Polarity in Listing
Style: 602025 200mAh
Be aware: this listing shows two different polarity orientations in the product photos. Yes, the description says to check polarity — which I did — but the problem is that the listing itself includes images of both red-left and red-right JST-PH configurations under the same SKU. That makes it impossible to know which one you’re actually buying. Polarity is not a minor detail. Insane. ... show more

  • Excellent Replacement Batteries
Style: 602025 200mAh
We purchased a couple of these batteries to replace dead ones in our cordless phones. They were well priced and exact fit for our phones. Installation was simple and they have worked flawlessly for a couple years now.
