which lithium do you have? if it's the 12 volt for sonar then yes. always charge it when you get home and it's up to temp. keep it top charged always. if it's 12 or 18 volt for tools then no. use your charger to discharge the battery if it's fully charged to 62% roughly. two solid bars with one flashing it close enough if you have four leds on the battery. leave the charger unplugged and insert the battery ino the charger to discharge it.i didn't write that article, but wanted everyone to know more about the batteries they use.
Odd. I had a Milwaukee 2ah in an unplugged charger for the last 4 months and it was still fully charged when I pulled it out last week. Didn’t discharge a thing. Still says 4 bars as I look at it now.
