There is an alternative battery to the standard lead acid battery and I have fitted one to my 4/4. I fitted an Odyssey performance battery about 3 years ago, which has the advantage of being (supposedly) much longer lived than lead acid. It also has the advantage of weighing less than half a standard battery, whilst delivering more current for starting. Together with the cut off switch, the combination has been trouble free so far and I can recommend the Odyssey to all.
