You can tell the batteries are charging in the Lester Summit II Series by checking the CHARGE STATUS (Yellow) LED:

- If it is slow blinking, the charger is in the Bulk/Start phase.
- If it is fast blinking, the charger is in the Absorption/Plateau phase.
- If it is solid on, the charger is in the Finish phase.

All these states indicate the batteries are currently charging.

You can tell the batteries are charging in the Lester Summit II Series by checking the CHARGE STATUS (Yellow) LED:

- If it is slowly blinking, the charger is in the Bulk/Start phase (charging with constant power or current).
- If it is fast blinking, the charger is in the Absorption/Plateau phase (charging with constant voltage).
- If it is solid on, the charger is in the Finish phase (final charging stage with constant current).

These indicate that the batteries are actively charging.

Yes, the Lester Summit II Series charger can be used for both lithium and lead batteries, but only if the correct active battery profile is selected using the ChargerConnect app. If the proper profile is not available, it must be downloaded or obtained from Lester Electrical. Using the charger with an incorrect battery type can cause damage or injury.
