In cold weather the truck battery is using two times more power to start the engine because the oil gets thicker in the low temperatures so it needs more time to start the engine.

During the winter, you can use some protective cloth around the truck battery to protect it from the direct influence. This is also a good way to close the direct cold and warmth waves from the inside and outside of the truck and make some kind of protective bubble with a unique temperature around the truck battery.
Check the power level in volts to see how battery performs
The voltage of the truck battery is very important and it is an indication of your battery performance. To check the battery you should use a voltmeter. How should I do that?
- Shut the engine off
- Turn the truck lights off
- Connect the red cable to the positive terminal with plus mark (+)
- Connect the black cable to the negative terminal with plus mark (-)
- Check the voltage on an empty truck
- Check the voltage on a full load to see the performing strength of the truck battery

You can use a digital or analog voltmeter to check the voltage. Digital would give you more accurate numbers. Checking the power level of the truck battery should not be an option it should be a regular practice.
