First time posting - only a Visitor: but have been lurking for QST...
Over the past few months I've noticed a film of liquid forming on the top of the cranking battery in a 2007 Nissan Patrol.
This wet film now covers more than 2/3rds of the top of said battery and I'm asking advice: What causes this?? Is this an indication of a dying/faulty battery?? What should I do??
Kind regards
Jedo

most likely normal evaporation and condensation of acid vapours. A wash with warm water with a dash of baking soda will soon clean it up

As above,
Might pay to check the electrolyte level in the cells too, and top up with distilled water if necessary..

Phew...

Those replies are re-assuring...
While lurking - have been reading about batteries over-charging and boiling over and bursting... and regulators failing...

Nice to know mine is a simple thing with a simple solution.
Thanks

Yep, what the honest Mr Olsen said, dissolve some Bi-Carb in hot water and pour it over the battery.

Do that say every 6 months and the problem will never appear again.
