The battery works fine for a fell months , after that it shots down after a couple hours of use and than , only works for less than 10 minutes in a low volume.
Now it's time to replace the battery.

BE CAREFUL WHEN PURCHASING THIS!! i just got mine yesterday, and not only was it USED, it came with SUPER low battery, and it WILL NOT hold a charge. I basically got one that is at the end of its life, to the point where it cant even hold a charge anymore. there are other much better ones for this price!!!

The battery life does not last very long. We own four and they are all the same. But it does not bother me because I can restrict there time on them. :)

The batteries charged up and worded fine for about 3 months, and then started to lose talk time.  I use my house phones about 30 minutes a week and usually no more than for 2-5 minutes at a time.  I would let the batteries drain about once a month.  But 6 months after getting them, they show a full charge but last 1-5 minutes max.  Would not buy again.

Battery life has been very inconsistent on these. Some lasted the expected 3 months, others only lasted a week or two. Not sure I would buy again given this since I can't trust them.

**Edited: customer service contacted me within a few days and offered a refund or replacement. I received a replacement within a few days, and they are awesome! Thank you for the prompt contact and replacement product. I am one happy customer!**

I give 1 star for battery life. The sound was great, had no trouble pairing, button controls worked great, and I liked the way they fit. Battery only lasted 30 minutes at the most!!!! Will be returning!

I bought 3 of these battery packs because i hav a 20 and a 100 battery backup. well I thought these might do good for a game or a cell while on the road at times... WRONG!!!!!! As I said I bought3, and when i started to charge the first one I set it aside for about 2 hours and came back and it was charged. GREAT!!! then I hooked up the second one and did the same and came bac to it in about 2 more hours and it indicated that it was DEAD no life at all. So I let it charge for an additional amout of time. well 6 hours more and it was still DEAD!!!!!!!!!!!!!!!!!
So I decided to try the 3rd one and hooked it up and charged it for about 2 hours and checked to see if it was holding a charge and NOPE!!!!! it wasn't charging either. the first battery pack held a chrge for about one day and that wasn't any where near a full charge back up. I tried to recharge it agin and none of these batteries are working. I suppose they have become the next best thing and that is an over priced paper weight.<a data-hook="product-link-linked" class="a-link-normal" href="/Black-Decker-CPI10B-10-Watt-Power-To-Go-Cordless-Compact-AC-USB-Power-Supply-Black/dp/B000SZS9LO/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Black & Decker CPI10B 10 Watt Power To Go Cordless Compact AC/USB Power Supply (Black)</a>

To bad they cant make the battery life longer both after a charge and over the long run. 6 to 7 minutes is all you get and then charge it for 45. Also after about 8 weeks, (not flying more than 1 time a day, the battery wouldn't hold its charge longer than about 45 seconds. :( . Replacement battery you can get not worth the $10.

I am disappointed in this product. it sounds good when I'm listening to music throught the headphones, but I have a hard time of people understanding me when I'm using the phone. Also I'm not happy with the amount amount of time the battery last, like about four hours, that's it!!!

Battery don't last as long as I would have wanted but still helps with a little extra battery last a day and a half or a little more if location and Bluetooth is off. Accidentally broke in my pocket when top was open . still use it but now carry it in  my bag . in my opinion buy it

They batteries work fine for about 3 months, thereafter they lost their juice...opened a new battery and this one only worked for about a week :( batteries shouldn't have to be replaced weekly!
