5.2. Charging Current
Due to their very low internal resistance PowerSafe SBS XC+ batteries will accept
unlimited current during recharge. The rectifier current can be limited to the load
plus 0.2C
10
Amps (minimum).
5.3. Discharging
Batteries must not be left in a discharged condition after supplying the load but
must immediately return to recharge mode.
Failure to observe these conditions may result in greatly reduced service life.
5.4. Accidental Deep Discharge
In order to protect the battery it is advisable to have system monitoring and low
voltage cut-out. A low voltage disconnect of 1.93Vpc (80% DoD) should be
applied to protect the battery from abusive over discharge.
Abusive deep discharge can result in premature deteriation of the battery and a
noticeable reduction in the life expectancy.
5.5. Operation in Hybrid Controlled Partial State of Charge

6. Data Recording
It is recommended that as a minimum, the following information be recorded by
means of regular data logging. The user must make this available to EnerSys in
order to validate any warranty claim.
1) Records of the commission charge.
2) The number of cycles performed and the depth of discharge of each cycle.
3) The duration of each discharge and charge cycle, and the Ah in and out (Wh
in and out).
4) Full details of the recharge voltage/current profile for the last 50 cycles.
5) A full history of the ambient and battery surface temperatures, recorded at
regular intervals throughout battery operation and life.
6) The time and date of each “event” (an “event” is defined as the start/stop of
the battery discharge, the start/stop of the battery recharge, the start stop of
any generator input power or other input power source, etc).
Contact EnerSys if you have any questions regarding maintenance.
7. Disposal
PowerSafe SBS XC+ batteries are recyclable. Scrap batteries must be packaged
and transported in accordance with prevailing transportation rules and regulations.
Scrap batteries must be disposed of in compliance with local and national laws by
a licensed or certified lead acid battery recycler.
