I brought a pair of Lucas LSLC22-12G 22Ah 12 volt batteries back in March 2016 as replacements for the APC batteries that were failing in my original APC UPS. On the strength of the outcome of the tests, I brought two more in May 2016 as my test batteries for when I do service and repairs of APC UPS units. The same pair has been used over and over again doing 80% discharge and then recharge cycling at 950 watts and still to this day are going strong. Originally they gave me a runtime to shutdown of 31 minutes compared the the original CBS cells that ran for 17 minutes (due to a 5Ah uplift in capacity) and now after 200+ full discharge and recharge cycles, I still get 29 minutes. I was advised to get the batteries from Tayna by a collegue who had experienced Tayna himself and I alway advise people to go here first for UPS battery swaps. I have brought both AGM and leisure batteries from Tayna and they always do fast delivery at a price you cannot argue with. Any data you need about loading, battery specifics, calculating runtimes....anything... They know what they are doing and never have given me any doubt that my battery needs are in experienced hands. My first expereince with these guys left me unprepared for the replacements as they turned up in a day, were well packaged and ready to go from the outset. Save your time and money by just getting what you need here... it's a no brainer
