"I sent a laptop battery in on 7/11/11 to be refilled and it worked just fine when I got it back until about 6 months later when I noticed that it would not hold a charge over 67%.
I contacted batteryrefill.com and, after some email troubleshooting, was told to send it back for warranty repair. batteryrefill.com received the battery on 3/19/12. On 4/17/12 I inquired about the status of my battery and got a response the next day asking for a week to find the problem.
On 5/18/12 I sent another email inquiry and was advised that the battery now only held 35% - 45% and batteryrefill.com requested another week or two to repair it or give me a partial refund.
On 6/8/12 I offered to send them another battery I had so they could use the charging circuit out of it if needed. This is the response I got.
"We can try, but it's not a guarantee Jeff. If you wish, you can ship us the battery with the circuit and our techs can try that out, but let our techs see if they can get the capacity to reach 100% before we go through that route. We'll keep you posted with an update within a good week. Thanks for your time and have a great day!"
I'm not sure just how long a "good week" is, but I still haven't heard from them with any update. So on 7/7/12 I sent a request for my battery, along with a refund, to be sent me. The email was read on 7/9/12 and as of today, 7/23/12, I do not have my battery, refund, or a response from batteryrefill.com.
Oh yeah. Don't bother calling them. Every time I tried I only got a message to call back during business hours even though it was during their published business hours."
