If you're wondering how long it takes to charge the battery of the Milwaukee 2720-21 M18 Fuel Sawzall, our research points out that it usually comes with the RedLithium XC5.0 battery.
This battery typically takes around 60 to 75 minutes to fully charge using the M18 and M12 multi-voltage charger. That charger is part of the kit and is designed to charge efficiently so you can minimize downtime.
Most people seem pretty happy with that charging speed since it hits a good balance between charging quickly and delivering enough power to keep going with tough jobs.
Just a heads up: following the manufacturer's charging guidelines can really help your battery last longer. If something seems off with charging times, maybe double-check if the battery or charger need updating or replacing.
And try sticking with the batteries and chargers Milwaukee recommends to avoid any issues.
In short, plan for about an hour to an hour and a quarter to get your battery fully juiced up so you can get back to work without too much wait time.
