Coming up on 3 years now. I have not charged these batteries that many times in that time frame. Maybe less than 10-12 times using an EBL charger. So far 9 have failed to recharge. I also have numerous EBL-AAA's and none of them have failed in that same time frame. That being said, none of them hold a charge for very long in storage and discharge quite fast. It is nice that they are rechargeable but wouldn't count on them when needed in an emergency, which is why I bought them. Good thing I keep a bunch of non-rechargeables on hand.Edited 1/22/23Did not ask for but received 2- 8 packs of AA's from the manufacturer a few days ago and have to say I was surprised. That is good service from the supplier. I raised it to 3 stars for the customer service by itself. I am not sold on rechargeable batteries and doubt I will buy more. I do thank the supplier for trying to make this right.
