Battery life span

[dr. d]

Yan din napansin mo on our montero. More than 3 yrs. Natengga lang ng 1 whole week na hindi nagamit kaya humina battery. Pero kung di siguro natengga ng 1 tuloy tuloy pa rin. De-tubig din. Unfortunately wala ako mahanap na de-tubig. Kahit sa gs mismo. Gs kasi stock battery ng montero

actually, even the maintenance-frees are still de-tubig.
it is just that, the manufacturer designed a long cover at the top, to hide the filler holes. if you snap off that cover (it is designed to be snapped on and off), the filler holes become evident. an ordinary philips screwdriver opens them easy.

also, batteries degrade faster, if kept in un-charged condition for longer periods of time. it seems, the chemical compound necessary to hold the charge, degrades if kept in its uncharged condition and falls off the holder grid. keeping the battery fully charged minimizes this scenario. hence the logic of trickle charging.
