Automotive Battery Chargers
There are many types of automotive battery chargers
available today. They are usually rated by their start rate,
the rate in amperes that the charger will supply at the beginning
of the charge cycle. When selecting an automotive battery
charger, the charge rate should be between 10% and 13% of
the battery’s 20-hour AH capacity. For example, a battery
with a 20-hour capacity rating of 225 AH will use a charger
rated between approximately 23 and 30 amps (for multiple battery
charging use the AH rating of the entire bank). Automotive
battery chargers with lower ratings can be used but the charging
time will be increased.
As a rule we recommend using a 3-stage charger.
Also called "automatic" or "smart" chargers. These chargers
prolong battery life with their well programmed charging profile.
These chargers usually have three distinct charging stages:
bulk, acceptance, and float.
Charging batteries properly requires administering
the right amount of current at the right voltage. Most charging
equipment automatically regulates these values. Some chargers
allow the user to set these values.
The majority of our range of automotive battery
chargers will provide Short Circuit Protection, Reverse Polarity
Protection, High Temperature Protection, Constant Current
Bulk Charge, 3 Stage Charging and a Constant Voltage Float
feature to hold the battery at peak charge without overcharging!
