Customer Reviews of Tripp Lite Replacement Battery Cartridge 51 - Maintenance-free Lead Acid
Perfect fit, great service11/15/2010
This was a tricky replacement to find for my 9-year old Tripp UPS; many sources did not offer it. Fortunately, Buy.com did and at a very fair price. This was also beautifully packaged and packed for shipment, and the delivery was right on time too. Being the exact model replacement battery, the fit was perfect and my ailing UPS is now up and running great again. Two days from order date to receipt, up and running again - couldn't be happier.
Easy replacement process11/14/2010
This is second battery replacement using Buy.com. As before, everything with order process was excellent. Battery was in stock, price was great and shipping was prompt and received in good condition. Recycling locally is easy for me so that is why I also returned to Buy.com with my order. Highly recommend.
I recycled my old battery first as we should all do anyway. This one works fine so far... 2 weeks now. By the way,the original battery lasted almost 4 years w/ daily use.
Nothing is as easy as it seems3/29/2009
After reading the reviews, I thought old battery removal would be a piece of cake. What I didn't account for was the battery had begun to corrode which caused it to expand. I was able to extract and expose enough of the battery body, by banging the case against a piece of wood, that I was able to attach two large C clamps to the case shell. I was then able to wiggle the battery free with my wife's help. The installation of the new battery was a piece of cake.
Easy and simple9/24/2008
Got the battery in the time advertised. It was simple and easy to replace the old battery. Just slide out, unhook the two connectors, hook them up on the new battery and slide it in. Takes 5 minutes.

Thanks for the rapid service. I ordered a new battery for my wife's 8 year old Tripp Lite UPS and I received it the next day--even using standard shipping. She is now happily revolted!

Tripp Lite UPS Replacement Battery6/27/2007
The UPS on the computer my wife uses stopped working and I was searching the net for a new UPS. I saw this replacement on Buy.com and decided to try it. I received the battery (free shipping!) in just a couple of days and the installation was a snap. I charged the battery overnight and everything is working great.
Great alternative to new6/7/2007
Fit perfectly as per Tripp Lite's website listing. Worked right out of the box.
I had problems with my TRIPP UPS. I thought I would have to buy a whole new unit, but this replacement battery made it 100% brand new again. Buy.com shipped it free, and although it was supposed to take 7-9 days, it arrived in only 3 days. Now that's service! The price was the best the internet had to offer. My order went as promised. I am absolutely thrilled with the product, and with Buy.com's service. I would definitely place future orders with is company.
