It's really best to use identical batteries in parallel, because if you mix types then as soon as some power is drawn from the two different batteries, they won't be identical voltage and one will discharge into the other. You can use somewhat different batteries in series, i.e. in constructing a 24V system.
You will have difficulty finding deep cycle batteries in Angola, but it will be easier in Namibia and RSA.

PS (10/15/09): Your solar panels produce only 7A max @ 12V? 120W panels should produce 7A EACH or 14A total; unless hooked in series for 24V (actually 35V regulated down to 28.8). My two 123W panels produce max 12-14A at >60 deg. N in the high summer of July. You may have one bad panel, check with a meter.
