Have been told bigger is better and yes also bigger price tag by a supplier
Is this the case or will any battery do the job

please help as need to purchase but want to get it right and not get stung.....

Thanks

The Ampage of a battery is actually measured in Amp-hours, (Ah), and is obviously a measure of the number of hours the battery will produce a certain current.
Amp-hours = Amps x hours.
This means that for example, a 70Ah battery would give 70 Amps for 1 hour, 35 Amps for 2 hours etc b4 going completely flat.
Since modern car batteries don't like to be completely flattened, this is a bit useless, but does give you some idea of the power stored in the battery.
With modern cars, there is a terrific drain on the battery when starting, and this is often not completely recharged when short journies are the order of the day. In winter, the oil is thicker, and the car needs even more energy to start it, the battery is cold, so doesn't work as well, and the alternator is often supplying lights, heater motor, heated rear screen etc as well as trying to recharge the battery, hence the winter problem of flat battery.
The answer is to buy the biggest heaviest-duty battery you can afford that will fit, and try not to let all your travels be short journies in the dark!
Hope this is of help.

Good advice.

Upgraded the battery on my STI7 the day after I had it.

Have got rather a lot of ICE though.

Despite the fact I do 60 mile journeys in the car, I always give it a charge every month or two. Did it yesterday in fact, and the battery certainly was not fully charged.

Go to a good battery specialist, where you will get a decent battery at a good price.
