Sovereign XS voltage question

[browndogwaswhite]

Just picked up a Sov XS and found that the P O had inserted Energizer batteries at some point. Leaked, corroded and swollen to the point where the plastic battery holders were broken. Cleaned the clip on leads and bought the replacement holders (for 8 batteries), same as original.
Now to my question - the owners manual calls for NiCad, 12v, 600mAHr or more. Whether I stay w/ NiCad or switch to NiMH I can only find them with 1.2v each. In order to get the 12v that's called for I need 1.5v (1.5 x 8 = 12v).
Am I being too worried about the 1.2v versus the 1.5v?
Thanks for any help.

AA alkaline will work fine, just not the AA photo batteries (too hot). I had a Soverign GT. You can also get a rechargeabke NiMH battery pack.
