puma defender max battery size

hi
looking for words of wisdom...im currently away from my land rover otherwise i would have took the measurements myself, i am after buying a better battery and was hopeful some one could give the max height and length thats available in the battery box for a 2.4 puma 110...
any help appreciated

The standard battery is pretty large, and is usually fine unless you are running auxiliary electrical devices such as a fridge or doing a lot of winching.

thanks for the reply
