For SLA or Sealed Lead Acid batteries. 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
36 Volt models: 12-20 hours
In order to maintain optimum battery life and run-time, please fully charge your lawn mower's battery after each use.
