2011 passat cc 2.0

none of my batteries lasted more than 2 years.. lol..

Battery technology has taken a huge leap recently. Many of you experienced batt life of less than 2 years. Well there are new & better batts in the market now. It all how much you want to pay.

New batts are EFB & AGM

AGM is the best and could cost $2k+. These could last 7years or more!

no, i didnt insulate, everything is kept stock on the car...but its good to have insulation as you mentioned, especially our hot weather here, which kills battery life faster.

From my personal experience battery sold here are just lower in quality and spec, hence in average local battery last only about 2 years.

When i use to live in US, most of the batteries came with 3-5 years warranty, they hardly die

There was a time Century batteries used to last just until the warranty was over, until I found this forum. Sifting through countless posts it's soon apparent that proper care & maintenance is required to maintain the state of health over a longer duration.

Since putting things into practice I've managed to prolong the Century battery to the 4 year mark compared to all previous Century batteries in the past.

The idea of this thread is to collect data to identify batteries that generally last more than 4 years, however having said that I still would want to change battery once it reaches the 4 year mark due to various other reasons.

i guess one of the contributing of my short battery life is the need to switch on the lights when traveling to work and home as well as start-stop traffic.

Hi VeeJay,

The US 3-5 years Warranty, does that apply to states like Hawaii & southern Florida too ?

2.WHAT CAUSES CAR BATTERY TO DIE QUICKLY?
Too Many Short Drives: If you are always taking short drives, this may be the causing your battery life to end too soon. If you keep on starting and stopping your car before your alternator has time to recharge, this would account for the reason why your car battery keeps dying and isn't last as long as it should.

Faulty Charging System: The battery is charged by an alternator(driven by a belt from the engine). If there is something wrong with the system, your car battery could be dying too soon.

Extreme Hot Temperatures: Hot weather can drain the life out of your car's battery. Build-up of lead sulfate crystals can occur when leaving your vehicle in high temperature for too long.The sulfate build-up can shorten the life of your battery and increase the amount of time it needs to be recharged.

Vibration: Vibrations from rough travel or a poorly-secured battery can shake loose or damage the plates.

TQ 'exeon' for Battery FAQ.

Never heard of vibration being an issue before but I reckon it should be with the hazardous chemical inside. A real big problem.

That's a very good question that needs a well thought & laid out answer. Will reply you again once I've straightened out my thoughts.

Warning ⚠️ I am no battery expert but since I've managed to hit the 4 year mark, now I want to try hitting the 7 year mark for battery lifespan. If that possible, I could increase the replacement battery period from 3 years to 5 years before the battery dies out.
