  • Application worked 👍
Style: 402030 180mAh
Replaced my rechargeable battery in my NeuroMD electronic back stimulator module that snaps onto the stickey pad that you put on your lower back.Had to cut off the wire connector and solder the red & black wires to the terminals where I removed the old battery leads.Now the unit functions again 👍✅

  • Works for what I needed!
Style: 502535 450mAh
I had to order a new remote control for my Alphard V2 and it died after 9 holes of golf. The company sent me a new one but didn't want the defective one back. I took it apart and measured the battery voltage at 0.85 volts. I ordered this one to replace it. The battery was soldered onto the circuit board, so I cut the connector off and soldered it to the board. Works like a charm. Other reviewers have given it bad reviews because they didn't bother to check the polarity of the connector. If you don't understand DC electricity, don't attempt your own repairs! ... show more

  • works, but be careful
Style: 401230 100mAh
i got two of these, one each for two halves of a split keyboard. they fit perfectly, and work great. like other reviewers, the batteries i got were in the wrong polarity for my equipment. while it was easy to switch the wires around, it could have been disastrous if i wasn't being careful. please double check the polarity before you plug these in. also, the wires were kind of short, but i was able to work around it, no big deal. ... show more

  • Wires are not 5cm long!
Style: 501624 140mAh
I would give this zero stars if I could because the product is described as having 5cm leads and the leads are actually less than 2cm.
