Review on Rayovac AA Rechargeable Batteries with Smart Charger - 4 Pack Battery Charger Bundle by Grace Brown

Charges the batteries supplied with the kit. So I replaced the batteries in my solar lights. Big mistake, the batteries only lasted a day. The original batteries that came with Walmart's solar lights 2 years ago lasted longer than these new, freshly charged batteries. It also doesn't charge the batteries that originally came in the flashlights, despite saying they are compatible, and now won't even charge the batteries that came with the charger. Every time you think it's charging the included ones or any other pair that originally came with a backlight, the charging indicator will flash.
