**2yr Warranty** Still good thru 05/23/2013.. One of the top best batteries ever made & HAS GREAT REVIEWS. This amazing battery contains Gel Electrolytes & it also resists from vibrations and impacts (which typically damages regular batteries & or wet batteries) The shelf life of this kind of battery is phenomenal, you only really have to even recharge the battery once every 8mnths which is backed up & guaranteed through the manufacturer warranty. WhicH is still active till 05/23/2013. THIS IS A STEAL, ESPECIALLY FOR WHAT IVE PAID ORIGINALLY. BATTERY IS IN PERFECT COND, COMES W/ORIGINAL BOX, PROOF OF PURCHASE (TO BACK UP WARRANTY) FULLY CHARGED & READY TO GO.
