Right now, Amazon is offering a 20% discount on its rechargeable batteries on top of the standard 5% you get with Subscribe & Save. This only goes for new subscribe and save orders on this item, but if you fall into that camp, you can get 16 of these AA rechargeables for just over $20 or an 8-pack for $14, which is a few bucks lower than the standard discounts we tend to see. That offer extends to 12-pack and 8-pack AAA batteries, too. They’re $11 each.
Need a charger? This 8-bay unit supports both AAA and AA cells, and it does its thing with USB power for just $14.
Don’t forget to cancel your subscription after you’ve gotten them. These are rechargeable, after all, and you shouldn’t need more for quite a while.
