Quick Installation Guide

To ensure optimal performance and maximize the lifespan of your REKOSER RDG12-26 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: 166 mm
  • Width: 175 mm
  • Height: 125 mm
  • Total Height: 125 mm
  • Weight: 8.3 kg

2. Terminal Configuration (F11)

3. Charge Parameters

  • Cycle use: 14.6-14.8V (-30mV/C), max. Current 2.1A
  • Float use: 13.6-13.8V (-20mV/C)
Maximum Current: Do not exceed 25 A of charge.

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.
