DEEP GELQuick Installation Guide
To ensure optimal performance and maximize the lifespan of your REKOSER RDG12-250 battery, follow these assembly and connection guidelines.
1. Space and Dimension Verification
Before proceeding, ensure the receptacle or cabinet of your equipment complies with the unit's physical measurements:
- Length: 520 mm
- Width: 269 mm
- Height: 220 mm
- Total Height: 220 mm
- Weight: 71 kg
2. Terminal Configuration (F12)
- Terminals: Ensure your system's connectors match the F12 type to prevent electrical arcing.
- Polarity: Check the positive and negative markings on the battery before connecting, to prevent short circuits.
3. Charge Parameters
- Cycle use: 14.6-14.8V (-30mV/C), max. Current 2.1A
- Float use: 13.6-13.8V (-20mV/C)
4. Safety and Storage
Maintenance: Sealed gel battery, maintenance-free and leak-proof.
Charging: Keep to the stated charge voltage: gel is sensitive to overcharging.
Cycling: Recharge fully after every discharge; never leave it discharged.
Storage: Store charged, in a cool and dry place, and recharge periodically.
