Has anyone ever looked at the meter on the OEM Panasonic battery and filled it with distilled water?
The meter has 3 levels:

Blue: Ok
Red: Distilled Water
White: Replace

 

Nobody checks their battery?

 

what's a battery?

 

Aren't these maintenance free? I look at it but never needed to add water until it died.

 

yeah, i added water(distilled) to the battery, it does nothing, I replaced it with a Die Hard.

 

These are supposed to be sealed batteries. I'm not even sure how you would add water. And by the time you would need to, it probably indicates that the battery has developed a non-recoverable issue.

 

Really, well I guess mine will die with-in the next couple of months.

 

The indicator on the battery comes off like a screw, and just pour the water in.

 

Ah! Thanks. I guess I never looked at it hard enough.

 

If you catch the low acid level early, you can properly add water into it and extend the life as the plates arent bare and wont cause a short.

If you ran the life of the battery, or are close to its death then adding water wont do anything to help it.
