Connect the Solo charger to the battery and a wall outlet. Charge the battery only with the designated Solo charger; using a different charger can damage the battery or cause a fire.
While charging, the indicator lights pulse at the current level, and when fully charged, the lights turn off. An additional indicator on the battery charger turns from red to green when the battery is fully charged. When completely drained, the battery takes approximately 1.5 hours to fully charge.
