MiadyRechargeable Lithium AA Batteries 8 Pack with Fast Charger, 1.5V 3000mWh High Capacity Lithium AA Batteries, Double A Batteries with 2000+ CyclesClimatePartner certified

This rechargeable battery with a charging pack is worth it. Its high amp rating is a definite plus. I love this product; I've tried it with a couple of applications, and it works well for me.

So far, these are fantastic. I purchased 2 Sets for use with my karaoke microphones, I use 8 batteries in 4 microphones every week and it was getting expensive. These charged quickly, within a couple of hours, I put 2 batteries in each of the 4 microphones and we had 3.5 hours of karaoke after which all 4 microphones showed a full battery. 7 days later, i turned on all 4 microphones, they all still showed full battery life and we did another 3.5 hours of karaoke. I haven’t had to use the 2nd set at all yet, that i bought for backup, and haven’t had to recharge the first set after 7 hours of use. I’m thrilled, they’ve paid for themselves already.

Have 1 battery that refuses to recharge.

It went very well, I would use them again

Amazing battery life. 1 week of traffic control walkies without a recharge is Amazing!

Honestly, I was doubting that this really worked as it stated & I can honestly say I was impressed. I have used the batteries & haven’t had to charge yet within the first couple hours of continuos use.

Saves a ton of money on my battery purchases

I'm sure the batteries are fine, but the charger won't charge any other AA batteries. They're AA's, an AA charger should charge them.
