You just have to be picky when you choose cars; my twenty year old Land Cruiser came with twin batteries factory fitted - though rather than one for starting and one for all the thingamajigs, they went with two beefy ones in parallel - 2*105Ah makes sure it starts every time.
I have been contemplating using the second one as an auxiliary battery after installing a fridge in the boot, though. Basically a matter of fitting a voltage monitor and a hefty relay.
- gugagore 7y agoTwo beefy ones in parallel don't really solve the problem. If you leave your 1-Amp (probably a gross underapproximation) headlights on over the course of ~200 hours, you'll deplete the battery.
- lb1lf 7y ago-It doesn't solve the problem (which is why I am considering splitting them now that I have added a ~1A consumer to the mix), but it does postpone the problem for long enough to (in most cases) ensure that you will realise your mistake before it causes you not to be able to start your car. Leaving the headlights on (~10A) as you leave the car in the evening will still let you start it in the morning, for example.
