Note: If a temperature sensor is not used, you must manually adjust charging voltages based on the battery temperature when in use.

If the charger has a preset charge profile for GEL type batteries, verify that these settings follow recommended charge settings.

4.1.1 Charge Parameters

The charge voltage should be set as shown in the table below.

4.1.2 Balancing charge

To avoid permanent capacity loss and sulphation in cycling operation the goal is to achieve a complete recharge (100% SoC)

after every discharge. Capacity loss and sulphation will threaten the battery's state of health.

The less complete the daily recharge is, the more frequently a balance charge will be required to protect the battery from

sulphation and lagging batteries. Depending on the cycling frequency, a balancing charge is recommended every 60 to 180

days. When short charging times are used then balancing charges are required at frequent intervals, preferably every month.

Balancing charges are also required after incidents of excessive stress for the battery (deep discharges with inadequate charges)

or when the individual battery voltages show excessive deviation from the average (lagging batteries and sulphation problems).

Should the voltage in individual batteries deviate from the average value more than the following limits, perform a balance charge.

Balance charge is generally required when the total spread between batteries is greater than 0.04V.

4.1.3 Commissioning Charge

Batteries lose charge while in transit or during storage. For this reason, a refresh charge should be given before putting

the battery into service. The battery should be considered fully charge when individual battery voltages have not risen for a

period of 4 hours. The surface temperature must not exceed 55°C (131°F). Recommended charge settings are as follows:

Nominal System DC Voltage
