Figure most 6 volt golf cart batteries at ~200 aHr. Connecting them in series doubles the voltage but the aHr. rating remains the same as one. 2 connected in series will give you 12 v.d.c. with an aHr. rating  ~200. Usable aHr. level would be ~50. (Figuring a 25% “Safe” discharge rating)

Never discharge a battery any less than 20-25% of its highest rating or it will shorten the life considerably. Never let the voltage drop below 11.9 volts unloaded. (Nothing drawing on it for 1/2 hour before testing)
