Are these batteries any good? Better than the Energizer one they had offered before? Saw these at the warehouse, same price as online.

The Amazon ones I bought stopped recharging (fail blink) in less than 1 yr - very disappointing.
did I have bad luck/batch?
That sucks. I've had mine for years and never had to throw one out yet but 2 batches of enelop are toast already

Quote from twinclouds :
1300 looks like the capacity after 1 hour charge for AA batteries. When charged in full, AA should be at least 2450 mAh.
You are flat WRONG if you are talking about the kit with the charger. This Duracell kit it total trash! The charger cannot charge individual cells (but rather have to be in pairs only), and the cells appear to be made in China.

If these cells are made in Japan (unlike the ones in the kit) then these would be a pretty decent deal.

They once were when they were made in Japan, but they switched to China made cells several years ago.

Package still says "Made in China" on the back.

Thanks for the info!

So even at this sale price, these 12-packs of Duracell batteries aren't a good deal either. Over $2 per cell is way too high for a cell made in China! The best "standard" deal (meaning you can get it anytime) would be the Ikea Ladda batteries as even their latest iterations are still made in Japan. IIRC, you can get a 4-pack of 2450mAh AAs for $8 and a 4-pack of 1900mAh AAs for $6.

Just posted this thread for a Energizer Battery Kit, 6AA + 4AAA $22.99 @Costco, In-Store Only. Cells are "Made In Japan". AA's are higher capacity 2300mAh, AAA's are 800mAh. Thought some in this thread might be interested.
