    Car bettry lifespan - truth or myth?

    had an interesting and loud debate of sort last nite. Inbetween techno blasting, sweet nothing hotties cooing, and downing of beers, talk skewed to the lifespan a car battery.

    Hardcore supporter of century swore that the maintenance free battery can last 2 years...others countered we will be lucky to have it last 18motnths..heck even 12months for some brands.
    Then some said, century provides a 2 yr warrnaty against failure...truth or myth?

    Which battery do you used? Price for price, I rank AAM battery (1yr warranty) at about the lowest rung...and wont buy them anymore.

    12 months lifespan is too soon for any battery of decent repute. At least 2 years lah under normal load and operation. If that happen, obviously your car electrics is likely a suspect or culprit for undetected current leakage somewhere. Car electrics are not bulletproof nor last forever. They deteriorate and current leakages can occur, often not realized by owner. I've had friends telling me how come my battery don't last..and point the finger at the quality of that battery. I told them go see a qualified car electrician and get it checked thoroughly.
    OK, I'm still using a run of the mill Yokohama NS40 battery lead acid in my small banger since Sept 2010..and its still ok. Its biggest current draw is only when starting the engine, nothing much else, no car stereo no radio no nothing innit!
    Farnie thing is every few years I buy a new battery, there's some price increase.

    The longest span I had a battery running was 4 years. Brand RoadMaster...
    For my current battery, it's moved to the rear trunk. Attempted a DIY when I had the interior stripped for some derusting job.
    It's 2 years 10 months and counting. Brand Century...

    Longevity of the battery depends on factors like:

    - Electrical demand from the engine and management system (and other add-on like audio system)
    - Engine heat
    - Efficiency of the alternator
    - Correct capacity as per manufacturer recommendation

    Is brand important? Let me share an experience with you....

    I used to own a BMW motorcycle - the K1100RS - which was supposedly ahead of its time back in 1994 because it has ABS II, shaft-driven (not chain), single-arm front absorber (paralever) etc... it also uses a dry cell maintenance free battery, special BMW branded and costs a migraine-causing RM700 and cannot find anywhere except in BMW shop....

    Then one fine day, a buddy of mine who was a sales director in a medical equipment company came by the house in USJ4 to take a look-see at what the big hoo-ha was about BMW bike technology... I lifted up the bike seat to show him the electronics etc and then he saw the battery... and said "wow! that's the same battery I bring in from Japan for the medical equipments I sell to specialist hospitals lah.... wah BMW-branded lah...."

    The batteries in medical equipments like incubators, lights in operating theatres etc were used as stand-by in case electricity from TNB fails or trip...

    When I told him I paid RM700, he said BMW - Banyak Makan Wang! - because he said he can sell me one for RM100. It was YUASA branded and brought in from japan. From then onwards, all BMW bikes were using YUASA battery as I bought them from my friend for them....

    That's cheap.... Batteries are taxable items... But there's a chance if he brought in declared as medical products, it's tax free...

    It's not the brand. From personal experience it is the car. I've use so many brands including AAM which is probably made by Century. All lasted two years or more until sometimes I have to replace the battery voluntarily because I don't want to push my luck.

    My worse experience was with the Peugeot 308 THP. When I sold the car after 26 months the car was on its third battery.

    my experience is 2-3 years.

    You can call your familiar car service shop to come to your house to replace the battery..

    Nowadays, most of them have a desktop in their shop. Just give them your plate number, they will know the battery and tyre spec of your car (from the previous service record).

    yup...me too SM...I use Yuasa for all except the shaky iron-horse, it carries its very own house brand too Yes, it looks good with its own logo. I paid me an arm & a leg for this yanky battery so it is always on a low charge...

    I use century too for my 2 cager tincans....one is already 1yr 10mth, the other just 10months. Had AAM before and gave up cos AAm battery lasted gam gam 13month! After 12months guarantee! ^%$#!@@!

    Wonder if Bosch is better? Yes, everything is on OFF mode when starting the car...and seldonm was it run on idle too. Nope all the alternators are functioning A-Perfect.

    I still have my doubt on the MF battery...maybe I will change to the wet ones...fill it with water every other week. A regular task for a beachbum..

    I use AAM battery because I can get them to change it for me at any time of the day or anywhere in Klang Valley. Anyways, I bought one last year and it died after 6 months. AAM technician came and replaced it for free and the warranty starts anew !!! Haha....

    What's the conclusion ?

    Which brand is the best in terms of long life and low cost ?

    I don't think there's any benchmark or measure which is best. Rest is all hearsay and your luck.
    I bought a local GP brand (that GP Batteries) lead acid type, now 7 months and seems ok..if it last 2 years or slightly beyond, I can't ask for more..
    One thing though, a bad regulating alternator may over or undercharge the battery during running and reduce the lifespan. Unfortunately most people won't realize anything as the car doesn't have any alternator diagnostics to indicate malfunction, only the idiot lamp indicator which automatically goes off after engine start up. Long ago, I used to install an additional volt and amp meter to the car electrics for basic monitoring. It should read a steady 13-14 volts when running.
    Vintage British cars especially GT models had these as standard. Those Smiths/Lucas meters..how nostalgic!
