Battery drain...

[LotuStuart]

Hi all. I find that my battery drains even if I leave the alarm off-actually, does the alarm drain even if it is off? I suppose it must, otherwise I couldn't turn it on!

Apart from the radio (which I know draws a little to keep the clock running), what other current drains should I look for please? I have a battery tender but will trip over the lead if I leave it permanently connected.

The alarm circuitry is always powered regardless of whether the alarm is armed or not. Part of the ecu circuitry is similarly always powered.

Yes, it does drain all the time.   I highly recommend a Lotus Battery Tender.  This has taken away a LOT of frustration when starting up my Esprit.  ??

The factory carries them (I think are included with new Evoras) and I have seen them on EBay and from Lotus Dealers.  This one does have an easy disconnect break in the middle of the cord, so you can disconnect in 1 second (without unplugging from the wall or battery) and not trip on it while not in use.

Cheers

I highly recommend a battery tender also, just recently bought for my Esprit also. These cars really do have a preference on having a well charged battery.

I know the thread  is a bit old, but....I installed a generic battery  tender....hardwired to my battery. It has velcro  on the bottom and I have the plug lead fished thru the boot and the cord is below the bumper. Doing it this way allows me to plug in the tender without opening the boot. I have it always plugged in and has eliminated any battery  drain  issues. Mark
