Batteries delivered very quickly Batteries delivered very quickly, a perfect fit for my UPS, and worked perfectly as soon as I installed them. At a price that can't be beaten too!

Batteries were promptly shipped after… Batteries were promptly shipped after some back and forth emails concerning questions I had. Nobody answers the published phone number but they do respond to emails. One of the 4 batteries I ordered was defective (7.3V, not 12V) and they quickly sent a replacement and paid for the return costs. Very happy with the battery backups for my Liftmaster garage door opener overall. Literally plugged them in and mounted the pack back on the wall. Posted video on their website was all I needed to understand what to do to replace old batteries.

Great product at a great price Great product at a great price. very fast and reasonable shipping. Fantastic customer service.

Great Prices and Great Service Rarely has an online purchase gone so well. First Raion Group had the best price for the replacement batteries for my Cyberpower Back Up Power supply -- by far. About 33% less than the next lowest price out there. Cyberpower charges $104 for the replacement batteries; Raion Group just $30. The ordering process was smooth. And much to my pleasant surprise, the package arrived two days later as promised. Cudos to them!

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!
