On chargers that are fitted with a Battery Type DIP switch inside on the PC Board, the charger can be quickly configured for use with either gel cell, sealed lead acid, or liquid electrolyte battery types. The difference is the cyclic voltage limit setting (This is the first voltage limit, where the charger changes to constant voltage mode, which happens when the battery reaches about 80% level of charge). The DIP switch setting also has a small effect on the float/standby voltage. If in doubt, we suggest use of the default normal setting, as that will give satisfactory performance with most battery types, with a voltage limit of 14.5V (per 6 cells). The sealed lead acid or normal setting is appropriate for absorbed electrolyte or AGM batteries. The two switch levers are marked on the PCB next to the switch, as N for normal and G for gel. The default (factory) setting, unless otherwise specified, is the \\\”Normal\\\” or \\\”SLA\\\” (Sealed Lead Acid) setting, referred to as normal. To set this mode, the switch marked N should be on, and the switch marked G should be off. The gel cell setting lowers the cyclic limit voltage to 14.1V (per 6 cells) and to select this, the switch marked G is on, and the switch marked N is off. The Liquid electrolyte battery setting increases the cyclic voltage limit to 15.6V (per 6 cells) and to select this both switches should be off.
