CR2450 Rechargeable Batteries 4 Pack 3.7V High Capacity Rechargeable 2450 Lithium Coin Button Battery

They actually don't hold very much power and run out of juice almost immediately. Some wouldn't work on the charger after only a single use. Definitely need improvement, almost a good product.

First order arrived corroded - replaced by seller.Second order (replacement) doesn't hold a charge very well.I have the CT Energy charger to go along with these, so I'm assuming I have the best possible combination to keep these things going.I charged all batteries after recieving them - some appeared to be nearly depleted, straight from the packaging.Most of the batteries went into the motion sensors I have around the house, and the rest are in a storage case in my desk. The batteries in the motion sensors last about 3 months - not horrible, but not great. By way of comparison, the Energizer, non-rechargeables I have last about 4 months ~ 6 months, depending on the room. On a couple of occasions when I've swapped in the 'fresh from my desk' battery, it shows up in the Zigbee2MQTT dashboard between 35% and 75%.On the plus side, I can keep recharging these, and it's only mildly annoying to replace with a fresher battery. I do have to wonder about the longevity.I have tried one other rechargeable 2450 and they are pretty much the same, so I guess they're all coming from the same place with a different name etched on them.If using for something critical, have SEVERAL extra.

I was trying to be environmentally conscious and bought multiple packages of these for my tea light candles for the holidays. Have had to charge after only 3 hours use then after that, they wouldn’t even stay charged long enough to use within one day. That is to say I would recharge batteries and replace into tea lights, would leave off / not in use until all the batteries in tea lights were charged so I could use all at once, and then, voila-no charge left in any of the batteries less than one day later except the four just charged….which would stay lit for about 40 minutes and die. Regular batteries would allow for approximately 6 weeks of daily use for 8 hours daily for comparative reference as the lights are on timers. Would give zero stars if possible.

Don’t even bother with these. I bought them because these type of batteries get expensive to replace in little votive candles. But I’ve charged them a few times after they lost charge with about 8 hours usage. I have other rechargeable batteries that last a few weeks at least of use.

Have had them for 2 months and already no longer working. They don’t take a charge anymore!

Batteries die after 4 hours. Pointless if you use them in something a lot
