Battery Amp hours

[GMatthesen]

Anyone an electrical engineer or savy person to answer a question. If I put two 6 volt 215 Ah batteries in series, I get 12 volts. What is the Ah rating, still 215 or totaled to 430?
Winter projects, nothing like them...
Thanks
Gary

215Ah...

Wire in series ADD VOLTS, ampere hours stays the same.

Wire in parallel ADD AMPERE HOURS, voltage stays the same.
