Micro-USB Rechargeable AA/AAA Battery NiMH with Cables (AA 2 Pack)

good product

These are great. I use them in a AA to D adapters for use in a radio. Last a long time and never have to put them on the charger. Simply use the micro usb cable and a wall wort.Update 09/09/2016I am lowering my review to 1 star. Went to charge batteries (only 2nd time) and one of them is dead. The charging led would not come on. I let them charge in case it was just a faulty led but when I put the one on my voltmeter, it confirmed it did not charge and was dead as a door nail. I attempted to contact seller but link went nowhere.

Awesome! I use them in my mouse at work. Lasts about 11 days before I need to switch it out.

The Batteries themselves seem decent enough, what I wasn't too happy with was that I paid one day shipping for 2 packs of 2 AA Batteries and I only received one pack the next day and had to wait an extra 2 days for the others to arrive. I needed these for a trip and I was only able to take 2 instead of four batteries.

One of the battery actually cannot be charged properly. I have to apply pressure at certain angle to charge the battery. Otherwise it would be a five stars review. Would like to return the battery to a place that can restore or recycle it.

So far, so good! I recently bought these so this will be an initial reaction and review of this product. I'll update a month from now to let you know how this went. First, of all I love new novel gadgets. These AA rechargeable batteries do that handsomely! What a smart idea! Having the mini usb "IN" the battery instead of having to use a wall charger. I love that the seller includes a two mini usb cable in one for charging. It's a bit short but since I intend to use these in my camera it fits perfectly into my camera bag. Be warned, these are 1000 maH batteries so not the longest battery life per use. I had some difficulty at first inserting the mini USB cable into the battery. I found that you need to angle it up (the mini usb) and then insert. Otherwise you'll do what I did at first and think they are broken. Not so, just finicky. I look forward to more batteries from Smartoools, especially higher voltages. I find these just right for my needs. I received a promotional discount in exchange for my honest evaluation and review of this product and I hope you agree.

One of the AA batteries will not accept a charge - the LED stays red continually - only used for one cycle. 50/50 chance, one good battery - one bad battery. Of course the return window has closed by the time I needed to recharge.

Idea of the batteries are great but over they suck I got to use them for a few hours but they never recharged so don't waste your time or money buying these
