What is the lifetime of batteries? people always ask kinds of such question like,how long life span of the UPS batteries? can you guarantee it for 3 years or more? ....
ohhh, my dear friend, Here is a big mistake, now i have to tell you The battery lifetime depends on the ambient temperature and frequency of charging and discharging. Higher ambient temperature and frequent charging and discharging(we call cycle numbers) will reduce batteries' lifetime. We offer one year battery lifetime guarantee. However, the battery lifetime is close to three years under normal use.
But there are more than lead-acid batteries in the world. Anybody remember NiCd?
