TF Battery drain

[Fraser]

I have to now park my TF on my neighbour's driveway, so cannot now keep my trickle charger connected, (at least not 24x7). So the battery ran down over the last two months so flat my "modern" charger would not even start to charge ! So it was back over to the old charger which eventually got the charge back to normal.

The car was left locked with the alarm set. I assume this takes some current over the days and thus discharges the battery. Is there any alternative ? I am thinking of using an old Krooklock, and just leaving the car unlocked. Yet when I look inside the unlocked car the little red light keeps flashing implying a drain of current from the battery. I have to say I'd love to meet the chap who thought up the system and tick him off for stupidity.

Disconnect the battery and then lock the car manually with the key.

I would do exactly the same. In fact I do this during winter season as a standard solution. no problems with memory in the alarm system 9it is not that clever )

in normal use the battery in my F and TF only survive for about a week, to remain able starting the car. A battery that has been in the car for two months without re-charging will probably be dead at they cannot live without being charged.

Er, well no; the battery charged up perfectly OK and off we went on a New Year Day toddle into Shropshire and Wales. Now I know it is OK to disconnect the battery, that is what I will now do. Thanks everybody.

Ditto all the above.

Because my TF tends to now only be used on high days, holidays and for the occasional track day, I fitted a battery isolator switch. No issues now even though the car is often unused for several weeks at a time - especially this time of year!

That is the convenient way to do it, As having older MG's as well, I installed them after checking they weren't equipped with a bypass for the radio. That wouldn't do no good.
