A decent electronic tester ain't cheap - it will cost more than several new batteries.

Older types merely measure the voltage while a heavy current is being drawn. You can do this yourself using an ordinary DVM and the starter motor. Disable the ignition or fuel pump and turn it over. The battery voltage shouldn't drop below 10 volts with a decent charged battery.

'Proper' ones these days are electronic and about the same size as a DVM. They use a short term pulse high current discharge, and can provide more information on the battery parameters than the old type.

With a bit of luck, they'll come down in price.

First saw one about a couple of years ago at my local independant high street spares place - Speedy Spares. Neat.

I wouldn't worry excessively about getting a flat battery, but carrying jump leads is well worthwhile in any case. It's usually not difficult to find a freindly type who will give you a jump. If you do get some, get some proper copper ones. Thicker is better - the current rating they quote on the packet is fairly meaningless.
