My husband is a major channel flipper. When he is watching live tv, he likes to constantly flip between channels so I feel like I am constantly changing the batteries in his remote control. I purchased this set of rechargeable AAA batteries for this purpose. I got tired of the expense of buying new batteries and felt bad about all those dead batteries ending up in a landfill. This set comes with the batteries only so it does need a charger which would have to be purchased separately in order to charge them up. I have only had them a few days but they seem to be holding up nicely so far. These will also be perfect for using in all those toys my daughter has.
