Battery drain

[terence]

Does anyone know what the current drain from the battery should be with everything turned off,except the alarm, on a chimaera.

Sorry for my english but i come from the netherlands. I also noticed that there is a far too high level of battery drain. I think it is because of the alarm. I did not find an other reason. But i found a simple solution. I have place a main electricity switch on the battery. So i can leave my car in the garage for 2 months or so without being left with a dead battery. Only cost about 15 euro or so. Wihout the switch battery was empty in about a week or so.

Sorry about the English, but I am from Manchester:

Battery will drain within 2 weeks, no question, it wven says so in the manual. I have a "trickle charger" which slots into the cigarette lighter which I leave on when I go away. When I get back, no problems at all. You can get them from most car accessory places, or if you want to pay full whack, off the TVR website.

It depends on the battery.. my Calcium battery will be ok for about 4 weeks, anything over that and its a non-starter (saying that, in that time something else will have gone wrong to prevent it from starting )

Regarding the drain.. don't forget the lowly dashboard clock, as well as the alarm.

In the winter my battery dies within a week.

In this weather I have no problems for 2 to 3 weeks.

I did get a new battery, but the old one has been fine ever since.

I will go and test the current draw now.


B-hot in that footwell.
My readings are - battery at 12.45 Volts & 24Ahrs
Draw with alarm & immobiliser on 200mA (.2 amp)
Draw with alarm off 200mA


I say "alarm" but all it does is operate doors, immobiliser & hazard lights.

I then could not get back in - drivers door not working, only passanger... Its happened before.

I assume the battery to be 36Ahr? Car was last used Saturday.

And the ICE battery backup, the ECU battery backup, flux capacitor, fridge to keep the delithium crystals cool...

AFAIK immobiliser (alarm) drain is about 300mA. Trickle charger about the same rating should keep it topped up in the winter between runs. This weather mines OK for a week or two.

Arf arf!

Re the battery, the only sound answer is to get a battery conditioner (which is a bit more advanced than a trickle charger) - cost about £45. Mine is an Airflow and plugs in the cig socket. Perfect.
