I'm really not sue. These batteries are far from indestructible, either.
AFAIK, no common chargeable battery technology is particularly happy being
left for long periods in a discharged state.
The best practical way to store lead-acid batteries is to keep them
constantly connected to a charger that maintains the correct trickle
charging voltage - 13-something volts (somewhat depending on
temperature).
A ordinary car charger is not, repeat *NOT*, suitable. We're not speaking
rocket technology here - it is just that ordinary chargers are so
incredibly crude devices.
Some "electronic" chargers may be suitable, otherwise any well regulated
power supply that can have the voltage set to 13-something and deliver
100 mA will do.
Failing this, a quick recharge every month or so is quite OK too, if you
can manage (I've tried, but failed). Leaving a crude charger connected
for extended periods will quickly destroy any battery.
