Poor Panda hasn't been driven for about two months, so I thought I should put the battery on charge first. Before connecting it up I tried starting the car - engine turning over well, but not firing. Probably a low battery effect, I thought, but I measured the battery voltage before putting it on charge: 11.99V according to my Fluke, so not too bad.
Charged the battery for about 8 hours and tried the starter again. Still not firing, but I persevered a bit longer and the engine started as soon as it started firing. I wonder if it took time for the fuel to get through after so long, or might the fuel be a bit stale from the last refill in January ?
Still, I'm impressed with how well the battery has lasted: 7.5 years and counting, and its first six months were stationary because I bought the car as a 6 month old pre-reg.
