Recently found that my Yuasa battery, which powered my golf trolley had given up. Upon searching the web found your company, which was extremely helpful by way of the "chat line". Ordered the replacement, which was delivered 48 hours later. It was cheaper that your competitors and I thank you for the excellent service.

Scott, Slough on May 10, 2012Read the full testimonial >

Order from these guys without really knowing what I was looking for, opened a chat box from the site and was surprised to find a human on the other end who could advise what I needed and links on the site to purchase. Placed my order at 23.00 and it arrived next day without paying for next day delivery. Next day thought I would chance my arm and once again asked a question, answer was immediate as was delivery next day again. Recommended my company look into using these guys brilliant service and turnaround time.

Good product, good price and good delivery! The battery in my APC UPS finally needed replacing after about 7 years. Critical Power Supplies made it easy to get hold of a new one. Not a replica, but an authentic one from APC, complete with detailed installation instructions and information on recycling the old one. A professional service.

"Many thanks for arranging AM Thursday delivery and for picking up the cost. May I just say that I always believe the mark of a good company is not just how they operate when things are going normally, but really how they perform when things get fouled up. I am happy to say that I feel you have responded very well both in communication and in action. This incident has not in any way generated a negative feeling but has in fact greatly enhancing my opinion of you organisation. Well done!"
