TD5 Auto Battery?

I think it's time for my TD5 auto to be treated to a new battery (hesitant starting and a few other associated niggles etc).
However, I'm a little confused with what I need to be looking at, according to what is already fitted and the owners manual I need a 110ah battery but when I look at suppliers online, they specify a 72ah battery.... can anyone tell me what I should get?

Thanks, Stoford.

Just go to a main Land Rover dealer the have 110ah

Hi there, the 072 is for Disco I cars - for a TD5 you need a 110 amp hour battery.

When it comes to a starting battery AMP/H is a useless figure and no one should buy a battery based on that.

The current needed to start an engine is very high and the figure you need to look at is called the CCA or Cold Cranking Amps. This is a measure of a batteries ability to start an engine. Regardless of the batteries size the CCA is the important figure, and really the only figure that matters.​

Cold cranking amps (CCA) is a measurement of the number of amps a battery can deliver at 0 degrees F for 30 seconds and not drop below 7.2 volts. So a high CCA battery rating is good especially in cold weather.​

That's so true for the engine starting function that the battery provides, but it does more than that doesn't it?

It also is the "buffer zone" between demand and supply (the alternator). In the winter on a high spec TD5 you might have front and rear screens working, heated seats, full lights etc etc. A battery that has a good reserve power such as 110amp/hr will cope better than one with only 50amp/hr reserve capacity, I would have thought?
