You do realize this is for switching off the 12v SLA battery usually when it is 
not under load right?


I've used a bunch of these over the years and they are fairly beefy for the job 
they are asked to do.  I even have one on my motorcycle and it easily carries 
my full traction pack voltage and current 48v 400 amps.  I don't expect it to 
switch that off under load, but I put it in the circuit so that I could 
completely disconnect my motor controller during charging.  I have a properly 
rated contactor on the other side of the circuit for any emergency shut offs.


These switches are more than up to the task of disconnecting the 12 volt 
battery for years without fail.  I'm just not sure if Cor is the type to settle 
for an ugly hack like this to a complicated problem.  He seems more like the 
type to grind through and uncover a proper solution, but even if that is the 
case this could be a temporary solution.

A battery cut off switch with only weak mechanical specs.  No maximum number of 
switching operations, etc. Now, that is interesting.

Hi Cor,


I'm not sure how much help you will get on a proper solution as you are kind of 
out there on the bleeding edge with the Leaf battery replacement thing and 
usually the one providing the answers :)


A possible hack might be installing a battery cutoff switch for the 12 volt 
battery.  Harbor Freight sells them for $8.

pack install: cold weather package...

OK, I did something to my Leaf that I need to get fixed, because now the
Leaf is charging the 12V battery whenever the car should be asleep,

as a result it is losing charge from the main pack.

It started two days ago when I removed the new (warranty replacement
battery) from this 2012 Leaf SL with cold weather package.

I do not know why it has a cold weather package, being in California it
never gets below freezing in a car so a cold weather package is quite
odd, but anyhow.

I installed a 2011 battery, apparently without cold weather package
knowledge in the LBC.

Since then, every time the car is supposed to sleep, it starts blinking
the 3rd charging LED and is actually charging the 12V battery to 14.4V
continuously,

resulting in 1 mile range loss every hour.

Anybody have a clue how to get the car to stop being confused about the
cold weather package?

Does the LBC need to be reprogrammed? I can modify the configuration
(serial) memory of the LBC, if I know what to change.

Or should I have the car's computer reprogrammed to tell it to forget
about the cold weather package? I do not need it!

Don't really want to pull the 12V battery contact off every time I want
to park the car more than a day and the energy loss

is quite a waste as well...

Any Leaf experts out there?
Cor.



BTW, the model nrs of the new 2017 battery that I removed and the 2011
battery that I installed:

2017 battery: 295B09RB9D

2011 battery: 295B03NA0A
