While this product looks the same on the outside as competitors, it’s what’s on the inside that counts. There’s a tiny pink bunny beating a drum in every battery that keeps you from having to recharge it as long as it possibly can. I’ve had mine in VR controllers that get actively used daily for a couple months and still haven’t had to use my first charge! I mean they just keep going and going and going…

Not a bad price for the rechargeable batteries. Has 4 AAA 4 AA with charger. The green light is on when charging and goes off when charged. The charger does both sizes. Saves a lot of money buying batteries. Once charged the batteries hold the charge for a good reasonable amount of time. Charges fast and if leave them plugged in for a long time does not overheat or damage the batteries. I bought this to see if I like it as I’ve bought other brands and was not happy. Ended up returning those. I’m definitely keeping these and will order more.

Bought it because it charges 1, 2, 3 or 4 batteries. I often need to charge 1 or 3 batteries for small flashlights and other devices. Works great, just not a rapid charger.

It takes all day to charge them, but it worth it!

Handy to have soare batteries . Nice they are rechargeable

Charge does not last a week for intermittent use.

Horrible purchase. $30 right in the trash

I bought these to put in a puck light that uses 3 AAA batteries bc I was going through regular batteries too often. I put 3 fully charged AAA batteries in and by the next morning there is no light. I was shocked! I've now had to recharge these batteries 3 times in the week that I've had these!

Bought 6 over 2 years period. 5 chargers died!!!! And 7 batteries swollen! That's terrible! Energizer only paid back ONE last year. Definitely horrible! Just the idea of going through lenghty hassling to get the warranty makes me give up!!!! But won't recommend this for long term use at all! If you're looking, for something that will work 3 to 6 months or less, then this might be okay. But more than that, batteries start swelling and chargers JUST DIE!

Runs out fast. Have to charge daily. Used for gaming for about 4-5 hours
