I have a 65Ah battery in my D, this will mean that fully charged it'll deliver 65A for one hour or 1A for 65 hours. 160mA is 0.16 of an amp. Therefore it'll take 65/0.16 = 406 and a quarter hours to drain a battery, all other things being equal, and in a 100% efficient system :-) That's 16 days, 22 hours and 15 minutes. Do I get a gold star? If you want to keep your battery healthy and not disconnect it, then buy a cheap trickle charger that'll plug into the cigarette lighter socket. They are certainly popular with "proper" Lotus owners :-) Martin Ryan Wright wrote: >Short question: How long until the average relay, energized, drains my >battery?
