- This happens often, when you want to upgrade the unit to a larger size and use your existing battery system.
- Each UPS has a charging rate based on the age of the batteries. As the batteries age, the UPS charges them more. Therefore our fresh unit we sell you will have its charger calibrated to charge the batteries as if they were new. Since yours wont be, this charging imbalance will shorten the life of your used batteries.
- Unfortunately, we cant calibrate the charger unit to half-aged, or 1 year old.
