Deleepow Rechargeable AA Batteries Lithium 1.5V 3400mWh, AA Lithium Rechargeable Batteries 4-Pack 1500 Cycle (Only Battery) …...

The media could not be loaded. Not good getting dead rechargeable batteries. 2 so far in the new 8 pack! Will not take a charge at all. Recharger will not recognize the dead ones at all! Don't think this is a good brand. Trying the old jump start charging trick will not work there is no real voltage in a new battery. Trying to decide if it is worth the hassle returning them. I alrea dy use this brand and have their charger already! As you can see I have their charger from batteries I got a while back. The purple ones, work fine still. Out of a 8 pack of these newer black ones 2 will not charge. In their recharger. Then two more will not charge. No help from Seller, hopefully I'll get my money back. Dropped off at UPS today. Will have to try different brand too bad first set of 4 have been working great for over a year now. What happened to the company.

These battery's run my dslr and my oculus controllers . they last about a week of VR use and will do a full photo shoot with my dslr that's known to chew 4 1.5v disposeable's in 10-20 shots. The charger is a very smart charger that charges per battery and shows every battery's charge level so its easy to see when done.

I purchased these batteries to replace 4 year old previous model batteries from DeleePow. They appear to be a newer version of the batteries we previously purchased. Since they have similar specs as the older model, we figured we could use our existing chargers. We were wrong. These batteries will not recharge in the DeleePow model DLP-508 chargers we bought with the earlier batteries. There is no indication of that fact in the ad that I could find. Also, they do not offer the chargers without batteries. ZeeBooth customer service has been great helping me work out a solution. These batteries have proprietary tech that requires their correct charger to recharge them.

I got these to put in my doorbell camera. Yes, I know they say not to use rechargeables, but non-rechargeable lithium batteries seem unusually expensive, and I wanted to try these. The first thing I noticed was that my doorbell camera is now complaining that the battery voltage is getting low, and would I like to reorder some batteries? No, let's see what happens. A couple of weeks later, still a low battery indicator, but still no sign of stopping. They're working fine, and so far they've lasted at least as long as the alkaline batteries I stuck in there. Yes, I know I'm not supposed to use those either. The alkalines were fine, but they don't last very long in a doorbell camera. The charger itself has indicators on it that are initially confusing, but when the backlight goes off and everything seems full, then it's done charging. I had charged them when I first got it, but I had to top them off before putting the batteries in my doorbell camera. I was worried that after a couple of days they would die, but that didn't happen. So, the only real negative is that the voltage might be slightly low? It's apparently lower than non-rechargeables, but not so much that they don't work perfectly fine. I plan to keep using these, at least until Energizer stops charging an arm and a leg for their lithium batteries. I'll just wait until the camera stops working, and then I'll charge the batteries again and keep using them. It's too soon to guess what their total lifespan might be, but they have already saved me money over non-rechargeable lithium batteries.

This is the 2nd set of batteries that I have purchased from Deleepow. The first set of 4 were 3400 mAh batteries which worked great. But the battery charger that I had didn't work on these batteries so I bought this pack plus the charger. So this time around one of the 3200 mAh batteries that came with the charger did not work. It would not power any devices and it would also indicate fully charged on the charger. All of the 7 other Deleepow batteries have worked fine however. Deleepow reached out to me via email to make sure I was satisfied and so I told them about the defective battery. They offered to give me a partial refund because of this. Since I was compensated for the defective battery I am rating these 5/5 stars. Each of the 7 working batteries have worked like a charm in my VR controllers. They last an extremely long time and the controllers are extremely responsive and do not ever disconnect. Overall these batteries are a great bang for buck!
