@MiddingIs there any reason to hook up the 12v to a battery tender? Seems not.
From the manual;@Midding
When you park your 4xe for weeks at a time.... for say more then even a couple of weeks (unused) is when you would especially want to use a charger/maintainer on it...
Your owner's manual must address what to do in regard to extended storage of your 4xe. Suggest you carefully read your owner's manual...
I don’t have a time frame in mind I’ve always hooked up a battery tender to my vehicles. In this case I don’t want to cause harm or interrupt what should be happening between batteries. Will have to research/seek help before I hook one up.The Level 1 charger is pretty much a trickle charger. How long are you planning on it sitting in the garage between drives?
@MiddingFrom the manual;
The hybrid has a feature of periodic wake-up that occurs every three weeks. This feature charges the 12 Volt battery from the HV battery. This will happen as long as the HV battery remains above the minimum state of charge.
So if I leave the HV battery plugged in for longer term storage, theoretically it will take care of the 12v. For shorter durations, 1-2wks, use a 12v battery tender?@Midding
It all comes down to how long the 4xe sits unused.. You asked is there any reason to hook up the 12v to a battery tender......
For sure there is.... I know there is no harm, no foul and only lots to be gained so to speak, placing a 12v battery that is going to sit for many days / weeks on a battery tender/maintainer... At the least the battery health will be better thanks to maintaining it over those long dormant periods.
You will do no harm... or lets say mess with / disrupt the 4xe if you were to use a 12v maintainer/tender on the 12v battery during storage times.
@MiddingSo if I leave the HV battery plugged in for longer term storage, theoretically it will take care of the 12v. For shorter durations, 1-2wks, use a 12v battery tender?
No set plans for storage, just trying to increase my knowledge base about the 4xe and the battery interplay.
