Charging Gel Batteries; Charging Motorcycle Batteries - Eltek MultiCharger 1500 Description And Operating Instructions

2.6

Charging Gel batteries

Gel batteries are used in some vehicles.
With these batteries, you should make particularly sure that the charging voltage is between 14.1V
and 14.8V (or 28.2 - 28.8V in the case of 24V batteries).
The trickle charge voltage should not exceed 13.8V (or 27.6V in the case of 24V batteries).
When Gel batteries are used, adjustments to the MultiCharger 1500 output voltage (see section
5.4) must therefore be made with particular care.
The charging current should be between 15 - 40A for every 100Ah of battery capacity. Refer to the
technical specifications of the relevant Gel battery for the maximum permitted current.
Warning:
If a Gel battery's charging voltage or trickle charge voltage exceeds the levels shown
above, battery life will be shortened. If these levels are regularly exceeded, the battery will
be permanently damaged.
2.7

Charging motorcycle batteries

Motorcycle batteries generally have a significantly smaller capacity than car batteries. This can
lead to the MultiCharger 1500 maximum charging current (100A for 12V batteries) being too high
for some types of battery.
Should this be the case, the MultiCharger 1500 output current limit should therefore be set lower
(see section 5.6).
For the maximum permitted charging current, refer to the technical specifications of the relevant
motorcycle battery.
