It is entirely possible to own your Rover SD1 for a complete lifetime without ever bothering to learn anything about looking after a Car Battery.

If it’s flat, call the emergency service! If it fails, buy a new one! Always look out for the best bargain! Don't pay more than you have to! Yes! We all know about batteries don’t we? And the worst bit of all - they cost so much money!

On the other hand, an appreciation of the technicalities may save a lot of money in the long term.

But who really knows what a car battery is about? Do we perform regular preventative maintenance? Keep it charged but avoid overcharging? Do we know that temperature matters? That Heat kills car batteries and Cold reduces their capacity?

This essay assumes a 12-volt, negative earth, lead acid battery used to start petrol engines in cars like the Rover SD1 and explains why it is false economy to buy a cheap battery.
