Internal Battery
The S4K5U requires very little maintenance. The batteries are valve-regulated, non-spillable, flame
retardant, lead acid, and should be kept charged to obtain their designed life. The UPS continuously
charges the batteries when connected to the mains supply.
When storing the UPS for any length of time, it is essential to plug the UPS in for at least 24 hours
every four to six months to ensure full recharge of the batteries. Failure to recharge the batteries peri-
odically will result in permanent degradation of battery capacity.
The S4K5U is designed to allow the user to safely replace the internal batteries. Read the safety cau-
tions before proceeding. Contact your local dealer or Sola/Hevi-Duty representative to obtain the
appropriate replacement battery kit part number and pricing.
