yokohama marathoner

Based on my 1 time experience with Century Marathoner, disappointing and not recommended.

Not strong enough juice to start my car if I left it for more than 4 days. The lifetime also cannot reach 3 yrs.

food for thought
-if u cabut, (which is technically best for the battery) your alarm system is als disabled, and you lose whatever non-volatile memory your car has in store
-if you leave it as is, well a good condition battery will drain slowly i guess...

so, end of the day, pick your poison.... I would rather replace a battery earlier than needed than lose my car or end up with stolen bits and repairs, but that's just me  (not saying alarms are foolproof, but they certainly are helpful in being  a deterrent)

p.s. iirc, lead acid batteries like to be fully charged unlike lithium batteries.

then yeah, remove one terminal (just pluck the -ve side) then make sure nmothing ic able to touch it (if you can cover the terminal with some sort of cover

if you are asking why that first? one at a time will do, i mean why create more sparks than necessary, and for obvious reasons, its safer to pull the -ve than the +ve (same reason why tou might notice, some ppl dont even bother to cover the -ve terminal but mati mati +ve kene tutup)

if you are asking why just one, well you only need to pull one to break the circuit, and unless you want to remove the battery, no point wasting your time having to disconnect and reconnect 2 poles when 1 is enough
