Hi, I have a 2015 Chrysler 200c v6 with just over 40,000 miles. I love it, came with ventilated seats, an engine that burns rubber, HID headlights, dual LED fog lights, panoramic sun roof, able to play videos off the head unit. What I cannot understand, I am on my 5th battery! I’ve had it for 10 years, keep up with all the maintenance but this car eats batteries. Just when the battery warranty runs out, bam, there goes the battery. What am I missing? Why does this car eat batteries? Could it be the passive entry?

 

your issues is in you not driving it. 10 years divided by 40000 miles is 4k a year and if your getting the 2 year batteries which would make since to 5 in 10 years .
Get a mid grade battery 36 or 48 mo battery and drive it more then 300 miles a month. or you can get a battery kill switch when your not driving it for long times have it disconnected from the battery then reconnect it back up you will not have any draw on the system. I have had to do this with a few customers that dont driver there car much.

 

A “Battery Tender” is highly recommended for cars that are not driven regularly.
After sitting 2-3 weeks unused batteries are often weak or maybe even to weak to start the engine.
Computer memory and other acceptable drains do this. A few cycles will damage the battery and shorten its life.
