## Customer Reviews

### ⭐⭐⭐⭐⭐ Good quality battery that works
*by P***P on 13 March 2024*

I bought some rechargeable batteries before and they just never charged, or said they were charged and then only lasted me half a day.I have a windowless bathroom and a spider plant in the bathroom, because it gets very little light I decided to go down the route of using a grow light that’s powered from batteries.My last set of batteries would only last 3 or 4 hours, even with the grow light at minimum. I was sure this was down to the poor quality of the batteries.I have replaced them with these batteries and instantly I am getting 2.5 days out of them on the grow light.I am using a Liitokala charger and they are charging in about 3 hours, no overheating or signs of damage.These are long lasting and fast charging! Highly recommend.

### ⭐⭐⭐⭐⭐ Good 18650 batteries
*by A***S on 5 December 2024*

Please be aware that these are the version of the battery with a button on the end and will cause difficulties if you use batteries with the flattened end as they will not fit comfortably. they do however hold a charge well

### ⭐⭐⭐⭐ Works out of the box
*by N***9 on 11 November 2024*

Good price. Nice that they come in a storage box.
