Tear off sticker and open cap to add water

- maintenance free
- add water

topkek

Anyone added water before? A friend of mine also asked me to add water to extend the battery life. Is this true? Any experience?

maintenance free don't need to do anything, TS too much money and itchy hand.

why not buy water fill battery ???.. cheaper ,.. last longer,.. easier to open lid,..

Google you scary

Nw battery stil need add water meh. Buy la the dry ones

Actually got earlier thread

Then why not buy the non-maintenance free version then? It's cheaper and usually longer lasting than maintenance free batteries.

My maintenance free batteries usually last about 1 year, almost to the dot actually (but usually after warranty), and cannot be revived. The regular batteries, you just top up battery water once in a while (even if you forget, once the battery cannot crank the car due to water level in the battery too low, a water top up will usually be able to start the car d).

Last much longer, and cheaper to boot. I say bye bye to maintenance free batteries except for cars still under warranty.

LOL. .buy a more expensive battery so that it can work just like the cheaper version..

thanks for the laugh TS..

Hmm

Wow, this is something new, can last 8 years?

My wet bat never needed to add water before ( i still check it monthly) 1 yr je aldy kaput...... The battery look brand new.....

I replace my car NS40 battery with Lithium car battery, maintenance free for 5 years and more I hope.

Try those practices above on the sealed MF battery & see...

not all can do this
some actually don't have holes at all...completely sealed

Buy AGM battery

Can add water for longer life

Yes true.

I did this on my century. Lasted 4 years +.

At 2 years old, expecting battery life to be almost over since people say can Century can last 2 years only, I opened it up to add water. It was half filled.

At 3 years, open again, still full.
At 4 years, still full.

No idea if topping up helped.

Normally maintenence free is black plastic box, how to see water level to fill up. Wet battery usually white transparent easy to see water level

Half dry battery plates have shorter life

See the label is MF but the casing has level markings

From the top, use a small stick to gauge the level.

Century not what they used to be

Not true. Waste RM1.50

Better get a maintenance type battery

It's not hard to do the filling up every month

Because the share the same casing

Better in what way? Price not much different nowadays

Durability, can last longer if you fill up the battery water periodically

Based on my experience, no difference. I got normal one last longer than MF and I also get MF longer than regular one even on same brand. Those batteries just die when they die.

We wont know if we dont try, right?

I used both type of batteries before, Almost all the maintenance type battery last longer than MF battery, lol

Yes. When you got your new car (used or bran new) with your hard earned money, you will not forget to take care of your car need. Wash weekly. Check battery water level after each washing. Topping it even level dropped by 1mm .After some time you get lazier and lazier and ahhh... maybe later ...or next week it since water level will not drop that much

Last time the MF was significant in price difference. Now the price is not much different, so I just get the MF and not bother checking water lever anymore

These was my observation between both battery types over years of owning cars. I would say no advantage or dis advantage if you choose either one. The maintenance full once if end of life, you can pour out all the water and pour new acid to rejuvenate it and still good probably at least another 6 months.

I see...

wow,how much the lithium cost u?

well my observation differ from you
my experience with WET battery always better than the MF battery

my panasonic MF battery is now at 3rd year, still strong

Same battery capacity?

About rm500.
Power of China taobao.

yup
on my protong gen2

damn
the courier fee should cost u a lot since the shipment is heavy

lithium is not as heavy as wet/mf battery, the box itself is big but inside components are small
but it is considered as DG for shipping

Lithium battery is less than half the weight compare to a Lead acid.
Use sea shipping not too expensive haha.

Then you need to modify or change alternator too?

I didn't modify my alternator.

I think Lithium need properly regulated supply. The supply from alternator is crude.

The lithium battery has battery management system in there to manage cell charges.
Its not like connect the power source direct to the cells.

no need just pnp.. i am not using it but i have read Taiwanese company introducing their product. The circuit board is within the battery and there's other important factor like heat exchange (internal and external).

I was talking about charging the battery to alternator. The power needs to be regulated. otherwise no good to lithium battery.

Sounds like the battery has internal circuit to regulate the voltage fluctuations from alternator then.

yes thats correct
