Do you know of a quick release battery terminal or battery isolator switch I can use? As I don't use my Copen much these days, I always have the problem of the battery draining. My Copen draws about 0.1 amps when it is doing nothing (I think this is about normal). I normally give the battery a charge every 2 weeks, but over the festive period I must have forgot and have now have had to replace the battery! Looking on ebay / amazon there are plenty of battery isolation terminals, but I can't find any to fit our Jap JIS battery terminals with 13mm diameter posts. Any ideas? P.S. If you leave the boot open, the battery current shoots up to 0.2A
Try this one: JIS Japanese Battery Posts - Battery Isolator Switch Universal | eBay I have one fitted to my Copen and it works a treat! (I made the mistake of ordering the wrong sized larger post one before I found this one.)
A copen should have about 0.030 amp - 30 milliamps of stand by drain. Thus the battery will just over a month and still just about start the car. At 100mA - 0.1amp, you will burn away all the juice in the battery quite quickly. I think they have a tiny 40A/H battery on them, so at 0.1 amp drain you'll only be a week in before the battery is a non starter. Even modern complex cars with highly active and well populated CAN networks tend to have less than 0.05 amp stand by drain. So if your little copen really is doing 0.1 amp, I suggest there is something going on with it - e.g. radio, cluster, alarm, roof/window controllers.
