Replacement Batts Good Experience Did online search for replacement batts for my Liftmaster battery backup unit (Model 475LM). Found YouTube by Raion Group showing how to replace the batts alongside their advertisement. Liked the video and larger voltage of Raion batts. Ordered from Raion website with no complications, liked I could pay with Amazon pay, fair price, batts arrived by UPS within 2 or 3 days. Batts fit my unit perfectly, just as described in Raion video. Hope the batts last.

Thank you so much for a reasonably priced internal battery replacement. Like magic, it is now working as it should. BAM! ¤º°`°º‹(•¿•)›º°`°º¤

Very Rapid Shipping and GREAT Product I received the replacement batteries for the Battery Backup for my garage door opener VERY quickly. Great product that was easily installed using their install video. My garage door opener is no longer beeping at me because of the old failed batteries. Now if they just last as long (6 years) as the factory original batteries.......

20 year old Diehard 750 charger I almost threw out my 20 year old portable battery jumper because of old recharging battery won’t recharge. I found this replacement battery from Raion by chance on internet that was compatible to my old Diehard 750 portable charger, it was delivered in a timely matter. I installed the new battery and it’s charging up like it suppose to. A new average price portable charger $100. Replacement battery from Raion not expensive. Thanks!
