Some batteries, especially powerframe designs (a subset of AGM) will retain charge for 18 months at room temperature. If it gets too cold, the battery will cease holding charge at all. If you''re leaving the truck standing, I recommend taking the battery out and putting it somewhere the temperature won''t drop below zero.

Once the terminal is removed, tuck it in a place where it can''t accidentally come in contact with the negative post of the battery (you can tuck it behind the battery). Also, before you unplug the battery, make sure you have your emergency key (it''s usually clipped into the smart key) and ensure all the doors are locked.
Learn MoreAlong with this protocol, disconnecting the negative terminal first before the positive terminal is a must. The negative battery terminal, also known as the ground strap or cable, is directly connected to the vehicle's engine, body, and chassis. The positive terminal is connected to the starter, the alternator, and the fuse boxes.
If you remove the positive terminal before the negative terminal, the battery will continue to discharge. Removing the positive terminal first will cause it to touch the chassis through a spanner or wrench or some other metal tool, creating the same effect as putting both battery terminals together.
The negative terminal is typically connected to the vehicle's chassis, which is grounded. Disconnecting it first means you can work safely without the risk of electrical shock. This is particularly crucial for individuals without extensive electrical expertise. Simplifying the process of reconnecting the battery later is another practical point.
Disconnecting the negative terminal first reduces the risk of short circuits. If a tool accidentally contacts the positive terminal while working on the negative terminal, it can spark or cause an explosion. The National Safety Council advises this sequence of disconnection to enhance safety during battery maintenance.
The negative battery terminal, also known as the ground strap or cable, is directly connected to the vehicle's engine, body, and chassis. The positive terminal is connected to the starter, the alternator, and the fuse boxes. Disconnecting the negative terminal first before the positive terminal is a must.
Always disconnect the car battery in this order: first remove the negative terminal, which has a black cable and a minus (-) sign. Next, remove the positive terminal, marked with a red cable and a plus (+) sign. Following this order prevents electrical shorts and ensures safety during maintenance.
