I don't think it's possible for everyone to use their batteries for such a long time until battery companies kena gulung tikar because of market imperfections as not everyone listens, not everyone has full detailed knowledge about how batteries work, and not everyone is able to keep their charging system efficient. Example my client new vehicle less than 6 years old and the Charging System already nyawa nyawa ikan even with replaced alternator from the SC. Summore berani to ask me, how long the new battery can last compared to the previous 42 months especially when the Charging System already nyawa nyawa ikan. Battery warranty now void, dare to ask how long pulak ? Tu la tak mau dengar awal awal, now nasi dah jadi bubur. Kesian this owner. One word my boss will say, degil.

Don't Mess with Melaka sial. Just replaced my regular clients battery in a Honda City. There is a strange noise thats coming from the area where the alternator is but it's a sound that I have never heard before from failing alternators. The owner asked me if her alternator was in trouble but Charging Test is OK status with voltage of 14.45V, which is very good. She had checked with Honda SC and there is a long list of items which needs to be change but there was no alternator on that list. It's the outside shops that asking her to change her alternator !!! So I informed the client if she decides to change her good original Honda alternator out, she better get back that original Honda alternator at all costs. I doubt whatever they are planning to put in is going to be as good as the original stuff.

While talking to the owner, her Honda suddenly turned on its Hazard Lights by itself. I was like WTF ??? Nobody was in the vehicle. The owner and I were standing in front of the vehicle. The vehicle was in an OFF position. Keys not even in the ignition. Weird man. Wish I had taken a video of this shit. I have the alternator sound in video but dunno how to post it here.

can pm location??

^^^ this!!!

I'm using CTEK trickle charger for both my car and motorbike and their batteries last 3 years.

Yea my car back in 2013 batt lasted 1 year oni, then I buy the CTek Start Stop, charge every 2-3 months, the replacement battery lasted 5 years+, up till covid hits and I was hospitalized for close to a month and then the lockdown etc no one maintain my car etc.. then when lockdown lifted, it died..

True bro.
Really superb charging system.

But almost nobody charges their car battery la. Especially now cars got all kinds of gadgets, batt last less than 2 years. Combined with short trips etc etc.. sometimes less time died ald

Just go and buy an inverter DC welder and try it yourself

always use a bigger battery to charge the dead battery. You cant expect a Myvi battery to jump start a Merc battery....and pls...use THICK cables!

Mechanic love to use portable jump packs to jumpstart customer's car, and these jump pack has battery which are half the size of myvi NS40, jump pack may have something like 18-22 AH battery while a NS40 can have 35-40 AH. And yet those thing are perfectly capable of jump starting car with bigger battery like DIN70 and up. Thus a NS40 is more than capable of doing that.

True bro. Modern cars have lots of sensors that are "awake" so there's some parasitic drain on the car batteries.
Motorcycles nowadays are also fitted with lots of electronics (although lesser than a car) and will face these same problems.
Also driving short distances doesn't really fully charge a battery.
So to be safe, just plug in the smart trickle charger (like CTEK) a few months once is good enough.
