5Curtis Model 1624 Manual
4.0 SELECTING A CHARGE PROFILE
The 1624 Charger can store up to 10 charging proles, also called charge algorithms. This section
shows how to identify the default prole and select a new prole using the “tap method.”
Model 1624 chargers are also reprogrammable by using the dedicated programmer. Pre-2006 Model
1624 chargers with serial number prex DQCP allow pre-loaded proles to be selected but cannot be
reprogrammed with new proles.
Identify the default prole
1. Required supplies include an insulated
wrench, eye protection and gloves.
2. Disconnect the AC power source from the
charger, either from the wall outlet, or from the
IEC320 connector on the charger (Figure 1).
3. Use your insulated wrench to remove the
positive lead from the positive terminal on the
battery pack (Figure 2).
4. Reconnect AC power (Figure 3).
5. Charger will conduct a self-test of its LED
indicators (Figure 4).
6a. For 11 seconds after the self-test, the
charger will display its default charge prole.
Proles #1-6 will display on the ammeter, as
well as on the bulk charge indicator (Figure 5).
6b. Charge proles #7 and above will
display on the bulk charge indicator. If the
charge prole number has two digits, it
will be displayed by one or more ashes, a
pause, then one or more ashes (e.g. #13 =
) (Figure 6).
