Our cordless lawn mowers use a two stage charging process. 

The first stage of charging takes about 3 hours (depending on depth of discharge) and will recharge the battery to about 75% of its full capacity. 

The second stage of the charging process will charge the battery to its full capacity. Approximate times to reach full charge from a fully depleted battery are listed below:

• 12 Volt models:  18 hours
• 24 Volt models:  24 hours

In order to maintain optimum battery life and run-time, please fully charge your lawn mower’s battery after each use.
