Important battery safety information

Warning: 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 "6.1 HP T750 G4 NA/JP UPS, HP T1000 G4 NA/JP UPS, and HP T1500 G4 NA/JP UPS", page 16 and "6.2 HP T750
G4 INTL UPS, HP T1000 G4 INTL UPS, and HP T1500 G4 INTL UPS", page 17).
• 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.
