26 Buggered battery
Here we are in the depths of winter and just when you least expect it you turn the key and click, click, click… then nothing. Standard issue batteries are pretty average at the best of times but mid-winter will knock the stuffing out of them if they’ve been under the bonnet for a few years. If you’ve neglected the distilled water top-ups and you can see evidence of “Frosty the Snowman” gathering atop the battery posts, look out, the battery’s likely buggered. No-maintenance or sealed batteries are best, not reliant on your memory for service and built internally to cope with corrugations and heat.
