I was told to ck the water level in my battery on my trailer. It is a Centennial Deep cycle and there is a little clear window you can look down in. Seems like it has a green tinge to it but not sure... How do you ck the water in these things? THanks!

 

im not 100% positive but i believe if it has the sight window you are speaking of it is a sealed (maintenance free) battery, no way to check water.

 

Yeah, the little window is found on some AGM (Absorbed Glass Matt) that do not require water to be added.

It's still a good idea to wash up the battery and clean the posts and cables.

 

Thanks so I will leave it alone!

 

If you have a meter check dc volts if it reads under 12volts no need to check water get new battery

 

If its sealed like our stock truck batteries its really difficult to get the lids off. Having always put water in batteries (even maint free) I just had to try opening one of mine. Its the one that looks like a monkey with an axe attacked it.
