dual battery in disco '03 td5

Jacs,
I am about update my 2000TD5 for a new one (tomorrow I hope). I had the extra battery clamped down in one of the cargo boxes in the back (mine have been 5 seaters). I rescued the Optima yellowtop from the old car befoer trading it. I ran a heavy duty cable from the main battery back to the auxuiliary battery (50A fuse at each end) and used a manual switch (marine grade) instead of solenoid etc. You don't need to get an Optima. A sealed gel unit for about $140 from the battery factory will work too, I did this in my other car when I resisted shelling out $300 for another Optima. My original LR battery failed (internal derangement) so I fitted an Optima Redtop as the cranking battery. From my initial inspection I should be able to transplant the whole lot into the new car without modification.Bob

I use a gel-cel battery as my aux battery under the hood.... I run my engel 40litre and also my compressor for my locker........
Every time i make comment on here about how much fridge life i get from my battery i get bagged because no-one believes it can last that long without being started....

My batt is 120amp/hour @ 12volts and has kept me in cold drinks for a year without a hitch...._____________________________________________
