Charger Considerations

There are several different types of chargers (relay, taper or three- stage) which can affect the settings and prevent the CHARGE LED from illuminating.

Relay Chargers

Relay type chargers raise the battery to a set voltage level then shut OFF using only voltage as their parameter. Set the TM500A to the voltage only mode and set the voltage slightly below the charger turnoff setting.

Taper Chargers

Taper type chargers raise the battery to a specified voltage and shut OFF when the amperage decreases to a specified level. When using taper type chargers (pulse-width-modulated), set the voltage and taper amperage parameters slightly below that of the charger.

If the taper charger is a type that charges up to a certain level and then waits for a period of time to determine if the batteries are charged, then set the TM500A to a voltage slightly below the charger’s settings. Set the time a little shorter than the charger’s time period.

Three-stage Chargers

Three-stage chargers raise the battery to a specified voltage level and then maintain the batteries at a “Float” voltage and trickle current. Adjust the TM500A’s voltage parameters slightly below the charger’s float voltage setting. Set the amperage slightly below the charger’s float amperage setting.
