How to add water to these batteries?
I have the generic black batteries with no markings that came from the factory. How do you check/add water to these? It looks like the cap should come off somehow, but I can't figure it out...I don't want to pry hard enough to do damage....

Picture of top of Bats would help. Should be 2 oval covers about mid point of bat. the pry up if that's what you have. Then fill as needed with distilled water.

These are the batteries...seems like the half opposite the lugs should come off?

Those look like AGM's, no water needed.

Thanks for posting!
My batteries look the same in my 2015 3170ds and I wasn't sure either.

Definately not AGM's...I can hear the water sloshing around inside when I move them...label on top says not to tip them and keep the vent cap level and tight.

" maintenance free"
Non fill able. ( unless you are very persistent. )

You might be able to pry that part up. The hard part will be to seal it back together. Are they bad?
What does the voltage check?

Have had same battery in my Sunseeker. Don't bother with water. Replace the batteries with Interstates or better. Factory batteries are bad news.

I haven't checked the voltage yet, but they won't hold a charge. Drove from NJ to NC and parked it for a week with the battery shutoff switch turned off. End of the week, batteries were dead. I haven't checked for parasitic draw, but with the main switch off, there shouldn't be much there.
Just ordered a pair of Interstate PRO-27M's...at least I'll know what I've got....

These are NO maintenance WET CELL dual-purpose batteries. Under the flat cover..if you pried it away you would see 6 valve mechanisms designed to releive pressure if overcharged or shorted...these are NOT fill holes.
Expected useful life of such batteries if not damaged by bad charging or discharging is perhaps 3 years.
If they are having a problem holding a charge once fully charged...it may be time for replacement. When you do this...consider getting TRUE deep cycle wet batteries in either 12V or 6V configuration.
My own preference is 12V for a pair...6V if you're going to have 4 and are into dry camping.
EDIT: Just saw your last post... you'll be fine with those...a big improvement over what you had. Suggest you get a clamp meter and check out your parasitic loads when you get them since you don't want to kill them if there is a load issue. Suggest storing with negative wire detached until you have a chance to do this.
