such as bulk, absorption, float and equalize voltages vary from one manufacturer to another, and that gel
cell batteries have different parameters than wet lead acid batteries. An improperly adjusted battery
charger may cause damage to your batteries!
The maximum charging current for a battery is usually equal to 20% of the battery's Amp hour capacity (“C
Rating”) for lead acid batteries, and 50% of the battery's C for gel cell batteries. The C rate is numerically equal
to the amp-hour capacity for the battery. For example, a 280 amp-hour battery has a C rate of 280 amps, and
the maximum charge rate would be 56 amps DC. (Note that this is not the same as the battery's Cold
Cranking Amp rating.) It is important to also take into consideration that if two batteries are connected in
parallel, their amp-hours add, while batteries that are connected in series have the same amp hours as a single
battery since they are simply stacked for more voltage. Remember, paralleled = more current; stacked = more
voltage.
