highest battery prices in the USA?  It could be US!  Conversely if you change the question to who offers the best VALUE, that might also be us.  That's because we recommend only Lithium-Ion batteries and we uniquely offer a THREE YEAR WARRANTY!  Not a prorated warranty - a simple warranty.  If your battery fails within 3 years from date of purchase, we give you another.  All we ask is return of the defective battery.  We take care of everything else.  Abuse, of course, is excluded but anything relating to normal operation is covered.  Additional information is available by clicking on the image at the left.  Check us out - you'll be glad you did!
