Pay attention when charging the lithium ion battery!

Existing chargers that are designed for the lead-acid or AGM battery generate a charging voltage that is too high for the lithium-ion battery.

If the charging voltage is too high, the electronic disconnect switch of the Li-ion battery can open, which generates a CCM message in the instrument cluster.

Before charging a lithium ion battery, adjust the charging voltage of existing charger adapters once.

Follow notes on lithium ion battery.
