Non-Maintenance Free Battery

[ER-3682]

I think TS is not looking for maintenance-free battery.

 

He is looking for non-maintenance-free battery.

This kind :

This is Motocycle battery,,,

Can turn by hand. If too tight, use plier to turn.

 

 

 

the filler cap is flushed against top surface of the battery. something like this (+). a large Phillips head screwdriver is needed.

[Spinelli_ck]

 

Yeah, this is like the kind that I used to service.

 

Thanks ! I will keep a look out.

 

The filler cap easy to open ?

 

Thanks !

 

yes, easy. you need a large Phillips head screwdriver. do note that you need to top up with distilled water.

Use a coin.

Flood battery need to be top up from time to time with distilled water to compensate the loss due to evaporation. Here is how it is done with a hydrometer - filling and testing the battery electrolyte (it's a mixture of 35% sulfuric acid and 65% water solution) specific gravity reading.

I have this and the CCA tester (hopefully it is still workin).

I think so far I have service a few hundred of such batteries. :)

Ok lah, the same type.

I prefer the filler cap protruding out kind.

hi bro, where to buy such hydrometer?

This is new design with unbreakable tube and floating discs

hi bro, thanks! is it accurate and easy to use?

Hydrometer test is used since the day flood lead acid batteries were invented. Battery works on chemical reaction and if the acid S.G. is low the chemical reactions will be slow and no or low voltage will the produced.

I've a few hydrometer, imo the best one is this.

Are you guys going to charge the battery if the hydrometer testing finds it less than ideal ?

Battery should be fully-charged first, then you use hydrometer to check every cell.

If the reading is weak, it means the battery is badly sulphated.

You can't do much for a badly sulphated battery, other than replaced it.

That's what I thought.

find battery power international. They are big battery disti. bought a yuasa wet cell ns60l for 75 bucks in April.... gave up on MF battery when it die without much warning
