I've had the battery just about 3 months it no longer charges.  Is there a warranty?  I've found lately that orders  are no longer accompanied by a bill of sale.

After 3 months the battery is no longer holding charge. Not sure if it's the battery or the remote car itself causing issues, but this was the 1 battery change and it didn't seem to hold up to the orginal ones length.

I have had this product for over 3 years. It doesn't work now, as it won't hold a charge, and I have replaced the battery. I may have left it in the sun too long.

Bought this to replace damaged OEM battery.  For the first 3 months or so, the battery was fantastic.  Charged well, lasted as long if not longer than the OEM.  However, after 3 months of use, the battery simply does not last as long as it did at first.  It struggles to make it through a day with moderate use.

I was impressed at first; now, not so much.  It is adequate, but not great.

UPDATE: Anker customer service contacted me and has offered to replace my degraded battery.  Fantastic service!

All ok, but damage the battery after three months having bought it,
I think this happens because batteries are very old.

Got the battery less than 3 months ago, and it's already dead.  I'll definitely be trying a different brand.

Purchased in June 2014, the battery worked fine for about three months and now will only work in the camera for about 30 minutes and then it shuts down the camera.

The battery stopped working after 2 months. They sent me a replacement battery and it stopped working after 4 months. I was told the 3 year warranty only covers 1 replacement. The Description in the ad does not say only 1 replacement it says 3 year warranty.

During the first 2 or 3 months the battery is holding the charge as expected.  But beginning with the 4th month until now, it doesn't charge pass 1 bar on the phone.  We don't use our landline much (less than an hour a week) but when we do, we use it to call family long distance.  Frustrating when kids can only talk with Gramps for limited amount of time ... of may be it's a blessing in disguise ;)  Anyway, we are going to try the Energizer brand next.

It worked good initially but just stopped working and its not even been 3 months. And mine is very limited usuage 2 hours a day max so I wasn't stressing this thing out.

This fit great in my 2009 Macbook, and even came with little screws to help get the job done. For the first few months it held a steady 5 or 6 hour charge, but it's been about 3 months now, and the battery is now only holding 2-2.5 hour charge! Had I known the battery was just going to go back to essentially what I already had with my old battery after 2 months, I wouldn't have bought a brand new one. I expected it would last at least a year, if not more.
