there are 2 types of battery.
1) wet battery
2) dry battery
1) wet battery got 2 types
a) serviceable wet battery of commonly told as wet battery
b) maintenance free wet battery or maintenance free battery ( most people misleading MF battery as dry battery)
2) dry battery
how to differentiate
wet battery - the cap is noticable, and the body is transparent
MF - cap is hidden by stickers.
dry battery - no cap at all.
wet battery - need frequent refill battery water
MF - actually no need refill. wait until water dried up, battery kong, then change new.
that's why people thought it is dry battery.
the thing we top-up water is we are cheapjing enough like myself want to prolong battery life.

wet battery

maintenance free battery

tankiu for detailed explanation
so what ppl tell me is correct.
ramcar = MF
me cheapjing also, add water to prolong life

Batt3 shop guy said if only 9V, then got prob & need 2change liao!
Yup, best 2run engine @least once a day if not use car 4>1 day...juz 2bring its charge back up...
Me do dat under such circumstances...run engine till rad fan starts & stops...
