Very dissapointed of the my experience with UPS BATTERY CENTER LTD.I bought 3 batteries on May 2020 with 1 year warranty. And since last month I tried to speak to someone to answer my e-mail asking to change my batteries that are unloading too fast. No one answer me, and I call everyday and is the same answer someone will send you a e-mail.Never buy there, will be a problem if you need them one day to use you warranty or for something else.
