The Tenergy replacement battery that I purchased worked well for 7 months and then failed.Unfortunately, the warranty is only for 6 months.The vendor I purchased from (Battery Superstore) offered free shipping on my next purchase, but was firm on the 6 month warranty.
Bottom line - The Tenergy batteries seem to have short lifespans.If they typically lasted a year, I suspect the warranty would have been made to match.
