Warnings & Precautions
Charging
- For Emergency Lighting Use: This battery is designed for use in emergency lighting fixtures with constant-potential (float) chargers (typically ~4.5V - 5.0V).
-
Use Compatible Chargers Only. Do not use chargers designed for Li-ion or Lead-Acid batteries.
-
Never exceed the maximum charge voltage of 5.0V.
-
Avoid charging at temperatures below 0°C or above 45°C.
Discharging
- Avoid deep discharge below 3.0V (pack voltage). Deep discharging can shorten lifespan.
-
Do not short-circuit the terminals. High short-circuit current can cause overheating and terminal damage.
-
Ensure proper ventilation around the battery during operation, especially in enclosed fixtures.
Storage
- For long-term storage, store in a cool, dry place at a state of charge of approximately 40-50%.
-
Recharge every 6-12 months during storage to compensate for self-discharge and prevent capacity loss due to sulfation.
