Take it to a place that load tests them, auto store, car mechanic, its
usualy free. If it never operated it will be fine if the charger did
its job. Maybe the battery was bad 3 years ago, maybe it will be good
for 10 more. If voltage is is what it should be, around 13 then its
been maintained and might be ok. Low or high voltage kills batteries,
a crappy charger.
