4-Pack 1632 Rechargeable Coin Cells Batteries for Tile Key Finder,3.7V LIR1632 Lithium Rechargeable Button Battery Replace 3V CR1632...

Horrible coin cell. Doesn't even last half an hour. Even when you fully charged it still doesn't last. I'm surprised that a reputable seller as ZeeBooth would do business with a sleazy manufacturer called CT-Energy. You can't even send an email to this CT-Energy saying "page not found". Chinese rip-off all the way. Just wasted $50.

Easy good

Pros: 1. Recharge quickly enough 2. Save money in the long term 3. Better peace of mind 4. Don't need to stockpile, less waste, better for the environment Cons: 1. Don't last as long as non-rechargeable batteries, need to change out more frequently 2. Slightly thinner than non-rechargeable batteries My Quarq TyreWiz require these unusual batteries and the non-rechargeable versions are quite expensive, even if you order online and wait for shipping. On the bike, they go dead at random and inconvenient times. And there are so many counterfeits everywhere that you have no idea whether they're any good or how long they'll last. So rather than stockpiling the non-rechargeables for uncertain lengths of time in which they eventually die on their own, It's much less wasteful to use these rechargeables. Of course, they discharge more quickly, but I'm happy to just recharge them. Another downside I noticed is that they're very slightly thinner than the original batteries, so I had to add a piece of electrical tape to raise the connector height and maintain electrical contact. They could have made them slightly thicker to hold a bit more charge. Otherwise, I think the greater peace of mind and reduced waste are worth the extra trouble of changing/recharging more often.

Replaced my current battery in my Tile easily. BUT difficult to get it to register as full battery. I need more directions
