E46 318i Touring: Back on the road with new battery!

Despite paying road-tax and insurance on the E46 Touring it's been laid up for 6 months and with an improvement in the weather it's high time I put it back on the road. All it really needed was some air in the tyres and the brakes beating up. The battery was totally dead, however. The previous owner had put an AGM [automated glass-mat] battery design for vehicles with Start/Stop technology on it, which was great but clearly the 19 year old alternator and charging setup on the E46 was not up to the job of charging it properly. Ah well, it has lasted for over twelve months... 

I've always sworn by Bosch batteries, but the £100+ price tag these days, yes even with a Euro Car Parts discount code, is a bit too expensive for this car. ECP, as well as the parts dept. at work can offer a budget Lion battery for a little over £50, but I have been warned by everyone willing to give their fifty pence that these don't last five minutes and I should avoid like the plague. Ultra-budget batteries can be found on eBay for as little as £27, but who knows anything about their quality.

At this point I have to hand it to the parts dept. at work here, who loaded me up a Yuasa 3110 series battery [760Ah] for just £60 all in! Yuasa get a good write up, in fact I am told they beat Bosch in tests and are currently one of the best on the market. ECP could offer me a Yuasa for £67, but it was a tiny little square battery and this just goes to show how useful working or knowing someone in the motor-trade can be...
