I'm not fussed by the speed of the charger as I have more than enough batteries to cover the charge time , I would rather the charger look after the battery than do it quick , my batteries are numbered so I use them in order or if using a few tools , use batteries 1234 on rotation till there dead then 5678 etc You need ear defenders round the Makita batteries for the amount of noise they make Sent from my iPhone using Tapatalk
