Good evening all,

I did a few searches of the forum and couldn't find anything that matched my situation. I am leaving my 2013 ED for work for six months. While I trust my wife to spin it around town every week or so, in the event she doesn't, what precautions should I take in the event life happens etc? Seeing all the posts about the 12v dying and the HV battery bricking has certainly terrified me. Should I get the 12v charger and keep that plugged in while it's not driven? What about the HV charger?

Thanks!

Fort an extended storage period, I would:

1. Hook a small 12V maintenance charger to the 12V battery. I have rigged wires from the battery terminals to under the service flap (hood) to make this easier.

2. Leave the HV battery at 80 percent. Lithium batteries do not self-discharge to any significant extent.

3. Don't allow it to be exposed to temperatures below -20C (-4F) for more than a day or so.

4. If you have not already done so, get the BMS software update done at a MB dealer that does Smart Service. (Service campaign no. 2016060002). It should be free.

From the test unit my son builds. I think it's basically the same as the Odyssey unit:

I think that might be what you're looking for.

Could be, that update is not doing the trick. I've got a smart with this update who still got damaged by a dead 12V battery.

Thanks, that's good information to know.

Regardless of what I wrote, keeping the car connected to a good reliable 12 volt maintenance charger during storage longer than 2 weeks is highly recommended. Well, more like mandatory. If the charger is new, do a shake-down test by conencting it to a 12V battery for a few days to be sure it works.
