SHENMZ 6S 3200mAh Replacement Battery for Galaxy S25 Ultra

This battery got my Sereonic speaker working again. The battery is chargeable but the old on had nothing left to charge. Put the new one in and works fantastic. Not expensive.

My husband is very happy with it. The batteries already had a charge, worked right out of the box, and he said the light he's using them for is nice and bright.

Batteries are performing as expected so far

Works well for doorbell camera

The batteries do need charged they don't come pre-charged but they do work very well I've been using the same battery fully charged on a flashlight for like 4 days at work so once they get a full charge they work well

Not sure if it was the battery or the item that died so I can’t speak to it because the yard light only worked for a couple of days after putting this battery in.

Fast delivery and good quality battery.

I’m always up for having a few extra batteries on hand, but this isn’t one I can pick up easily. If I went to my local hardware store, the cost would be prohibitive. This I know because I’ve had to purchase a couple of smaller ones and was surprised at the exorbitant pricing. I do like the fact that these come in a small plastic case, a handy feature I like.I have a couple of flashlights that use the 16650 batteries and do like these. I have a charger for these and checked out the charge when they arrived. They were fully charged, something I appreciate and like. These can be recharged hundreds of times, yet another feature I’m into. Every now and then we get a battery or two that’s a dud, but for under $20 these are reasonably priced.
