Why has my battery gone flat?

[rondeo]

Not a practical question but interesting anyway.

Century batteries reckon modern vehicle charging systems (smart charge?) might be to blame, with CO2 emmissions causing the problem:


Q. Why has my battery gone flat?

Undercharging - This is the most common cause of a flat battery. Modern vehicle charging systems are designed to reduce CO2 emissions and improve fuel economy by increasing battery usage, while at the same time not providing sufficient charge to fully recharge the battery.

I wonder how true it is, and how much CO2 is needed to make a new battery.

This type of charging system does exist, Ranger as an example. But I feel it is not all that common.

Does it make a difference emissions/economy wise? Probably not enough to be noticeable

If the charging system is working properly, this should not be an issue.
Under conditions of high battery charge, the system relies on over-run to charge. Should battery condition drop, the system should charge as per a conventional system.

With approx 3 hours per day driving, and the additional "excitement" of headlights and driving light on, mine seems to keep a reasonable charge.

Go figure.......
