It might be, depends on the charger. My automotive charger is a 50 amp
car starter and a 20 amp charger. The charger will vary as the battery
gets charged. As the battery gets topped off the current drops to an
amp or so.

hook your charger up to your automotive battery and check the final
voltage after it has charged overnight.

if it is below 14.5 volts, it is likely not to harm your aircraft
battery if used to charge at a low rate. if it is above 14.5 volts,
depending on how long it is left "charging", it might.

it really doesn't matter to me, useta sell a lot of batteries to
people that used the monsta-charger set @ 50 amps to charge their
flooded-cell aircraft batteries. pull the electrolyte out and it looks
like dirty weak tea with black flecks on it. btw if your plane's
voltage regulator is set much above 14.5 volts, the battery will look
the same way...
