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!

Late day order I ordered these late in the day, and they got them shipped out same day. And they sent good communications on the status of the order. Installed them in 2 UPS, and let them recharge for 24 hours before I plugged in my very light loads (a wireless router on one, and a fiber modem on the other). Interested to see if there is any noticeable difference between the original lead acid and the replacement AGM batttery

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.......

Inadequate Packaging Packaging for shipment was grossly inadequate and customer service, while polite, was unwilling or unable to resolve the issue of damaged goods to my satisfaction. Return policy was overly restrictive and led me to return items and shop elsewhere. To clarify... I ordered 3 set of batteries: The first package was missing a battery (which was readily sent to me... off to a good start!). The second package was fine. The third package did not survive shipping, and had been "reassembled" by USPS. The shorted terminals happened in transit, long before I even even thought about installing them. I noticed it when I went to prep everything to do the work. We had an extensive thread of emails about this and where never able to come to a satisfactory conclusion.

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¤
