MAINTENANCE
The PowerSure Personal UPS requires very little maintenance. The batteries are valve
regulated, nonspillable, lead acid, and require that they be kept charged to obtain their
designed life. When connected to the mains supply, the battery is continuously charged.
When storing the UPS for any length of time, it is recommended to plug in the UPS for at least
24 hours every four to six months to ensure full recharge of the batteries.
Battery disposal - When the battery life is expended (see alarm indications), dispose of the
discarded batteries in accordance with local environmental laws.
