Pros

Two for less than 20 dollars & up to 1200 charges. Will update this review if something happens but as of right now, they are amazing!

Usb rechargeable batteries. Duracel and energizer rechargeable i usually buy. Just recharge and start over.

Cons

These are total junk. Not worth buying. I'm trying a pair that doesn't use this and will see if they fare better. Skip this one.

When charging these, please set a timer, and don't leave the room of your house. Can't charge in standard battery chargers. These are a rip off, unless you're willing to sacrifice almost half of the usable charge.

Because they are liion, the output voltage is higher than nimh batteries, and thus the won't work in all applications. They last about 50% or less than alkaline equivalent.

I am an electrical engineer and the concept is great but the product quality and replacement support is not findable further wasting my time. Center post on 5 of 6 batteries had “collapsed”.

Good battery life and easy to change

Lasted over a year of recharging maybe once a month and now the charge doesn’t hold as long.

Just letting you know that they do not hold up for more than a few months…

Price

Well priced, quick charge, last as long as conventional batteries.

Bought this for my red dot laser sight / flashlight combo … long lasting great price !

They're like $15, and you never gotta buy alkalines again.
