What type of batteries should I connect to my Inverter/UPS?
The choice of the appropriate battery depends on the following factors:
- Desired back-up duration
- Average operating temperature range
- Space availability
- Environmental factors
- Topping up requirements
UPS that come with internal batteries typically use VRLA (Valve Regulated lead Acid) batteries which are also known as Sealed Maintenance Free (SMF) batteries.
