Just thought I would pass this along! Check your battery water

[Jon]

Being winter up here in the Northwest I always leave the current
flowing in the Rebel bird to run my temporary heaters. So I know
that the battery charger is still charging the batteries and so the
battery water is evaporating. Just got finished with refilling all
four batteries as we are having a little brake from all the rain we
have had up here. Glad I did as the batteries water was almost down
to the plates. Jon
