battery in the drink

**oldbones** · 10th April 2007, 10:10 PM

slight oversight on the maintainance front caused me to forget to torque down a sea-ish level access hatch in the tub.
i call it old age, the wife thinks its salinity....(sorry)

oops i thought when i spotted the tub at the mooring staring its accellerating journey to davy jones. 30mins of frantic bailing by the team saw us all buoyant again.
no real damage save a residual whiff and bruised ego/pride etc and we enjoyed an excellent afternoon sail later with yours truley copping a decent sledging.

the newish (read expensive) deep discharge battery was well immersed, dead flat and smells of chlorine. the cells were not flooded but cant be certain whether any brine went into the battery.

any knowledge out there on suitable lead acid battery refurbishment process for these instances?

my only layman guess would be to drain, flush and refill with battery acid.
i've not attempted a recharge yet in case and (brine) contamination would ruin the lead plates during the charge cycle. but what do i know?

advice appreciated as ever.

Definately drain the battery and dispose of the contents as per the greenies instructions

Mate one of the most dangerous things you can do is put sea water into a battery cause when it charges clorine gas ( as used in WW1 ) is released , if in any doubt at all dump the battery contents and flush with pure/distilled water then refill with appropriate battery acid and you should be OK

When I was teaching marine safety the standard for batteries was if you had no distilled/fresh water then it was far safer to urinate in the battery than ever use salt water and it was in fact a failing question

sound advice thanks ashore.

i confess to not having the battery in a "battery box" (yet) but having looked at these in the past, i'm not certain that this would keep the top of the cells/terminals dry in case of possible future immersion.
better than nothing though.

hmmmm....
tried buying battery acid recently?
the good old sulphuric seems to be as rare as rocking horse doo-dee's

one fella stated they had to withdraw it as it is pretty useful to mr terry wrist!

anyone aware of a source (preferably around the frankston area) ?
