Anyone have any insight here? I have two Makita cordless drill batteries that I use infrequently. Stuck them in the charger, which lit up red, then after a while green -- like usual -- but neither battery would operate either my drill or my flashlight (i.e. appears they have no power). But the charger recognizes them, lights up red and then green, so this is not the usual situation where they don't have enough charge to trigger the charger. Any thoughts? Weird that it's both. Maybe the charger is busted somehow, even though it appears to be operating as usual?

Try wiggling the F/W switch as you pull the trigger, or pull the trigger
and slide the battery in and out a little as you do. Most likely in my
experience is a battery contact problem.
