Each time you jump start the car from a dead battery, your actions after that (driving somewhere, or rather car in READY mode (green car w/arrows icon), charging via L1 or L2 EVSE may not be sufficient to charge up the 12 volt completely. After all, we already know the 12 volt charging algorithm on the Leaf is crap.
And, unfortunately, running a lead acid battery flat can be bad for it.
I'd suggest getting a 12 volt charger to separately charge up the 12 volt. I have one of the Tecmate Optimate 4's (https://tecmate.com/?post_type=products ... y-chargers
). I have no idea what would happen if you charged on L1 and L2 while using this, so I'd recommend not doing that. I charge connected to the + post and have black connected to the black wire connection attached to the PDM stack, instead of the battery's negative post.
