1.6 BATTERY PACK MAINTENANCE
Your Greenworks mower is powered by a battery pack which,
when maintained properly, will provide years of useful life.
For proper care, adhere to the following instructions:
Always charge batteries after each use.
Whenever a battery pack is fully discharged and turned
off, it is best to recharge the battery as soon as possible.
Over-discharge of the battery pack means the battery life
will be shortened and the battery may become
permanently damaged. There is no need to fully charge; it
will be beneficial even if you only charge the battery pack
for 5-10 minutes. It is best to recharge it within 24 hours.
