2 week trip, storage

Mon Jul 17, 2017 6:11 am

Does anyone have advice on leaving the iMiev for a few weeks? (not charged or driven) - I'm thinking of charging to 80% - not sure if putting the 12v on a "battery tender" would be a good idea - thanks

Julian46, we have many posts on this topic.

Simply put, leave your main pack at around six bars (around 40%) and, if possible, attach a small smart 'float' charger (e.g. Battery Tender) to your 12v battery.

The reason for keeping the 12v battery on a charger is because there is a continuous low power draw (e.g., from the i-MiEV alarm system) which will easily run down our now older 12v batteries.

Hi, I'm leaving my 2102 iMiEV for 2 months. Last time I did this the 12 v battery died and I had to recharge it to get the car going. My plan this time was to disconnect the battery but when I tried to do that just now the alarm went off & practically deafened me.

It is under cover but no power socket nearby, so I can't use a trickle charger even if I had one.

Does anyone know:
a) if disconnecting the 12v battery would cause any damage
b) how to disable the alarm to allow me to disconnect the battery quietly
