Battery module replacement
Safety recommendations
Caution: To prevent personal injury from hazardous energy:
- This operation must be performed when the UPS is switched off and unplugged from the AC source.
- Do not disconnect the connector while the unit is operating from the AC mains or in reserve mode.
- The battery connection must not be disconnected while running in reserve mode.
-
The battery can cause electrocution and high short-circuit currents. The following safety precautions are required before servicing the battery components:
- Remove watches, rings, or other metal objects from the hands and arms.
- Use tools with insulated handles.
- Do not place tools or metal parts on top of batteries.
Replacing the batteries
- Read and observe the requirements in "Important battery safety information" and "Battery care and storage guidelines" in this section before battery module replacement.

Note: Replace all battery modules at the same time.
Important battery safety information
Caution: The unit contains sealed lead-acid battery modules. To prevent fire or chemical burns:
- Do not attempt to recharge batteries after removal from the unit.
- Do not disassemble, crush, or puncture the batteries.
- Do not short the external contacts of the batteries.
- Do not immerse the batteries in water.
- Do not expose to temperatures higher than 60°C (140°F).
Battery care and storage guidelines
Caution: Because of the short shelf life of the batteries, avoid storing a battery spare as a backup. Do not maintain an inventory of spare batteries on site unless a procedure to keep these batteries charged while in storage is implemented.
To maintain the batteries:
- Minimize the amount of time the UPS uses battery power by matching the UPS configuration with the utility voltage see HP T750 G4 NA/JP UPS, HP T1000 G4 NA/JP UPS, and HP T1500 G4 NA/JP UPS and HP T750 G4 INTL UPS, HP T1000 G4 INTL UPS, and HP T1500 G4 INTL UPS.
- Keep the area around the UPS clean and dust-free. If the environment is very dusty, clean the outside of the UPS regularly with a vacuum cleaner.
