4.0 SELECTING A CHARGE PROFILE

The 1625 Charger can store up to 10 charging profiles, also called charge algorithms. This section shows how to identify the default profile and select a new profile using the “tap method.”

Model 1625 chargers are also reprogrammable by using the dedicated programmer. Pre-2006 Model 1625 chargers with serial number prefix DQCP allow pre-loaded profiles to be selected but cannot be reprogrammed with new profiles.

Identify the default profile

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).

Figure 1: Disconnect AC power.

1. Use your insulated wrench to remove the positive lead from the positive terminal on the battery pack (Figure 2).
