Help with understanding my batteries.

[patrickemb]

Finally stopped raining the last couple of days and it's feeling more like fall. Decided to go check my batteries lubricate the rails on the trays the batteries are sitting in. Was going to check the water levels in the batteries but the cap says do not remove. All they would do is spin and not latch onto anything to open. Must be a reason that I don't know about. I have attached pictures. Can I get some info on these batteries? Do I need to check the water level? Will it hurt anything if I wash them down with a water hose to get some of the dirt and dust off them? 2 of them are interstate batteries and I would guess these are the motor batteries. Thanks

You have agm batteries. They are not like normal acid batteries. Here is some info on them. Cheers

patrickemb - Consider yourself fortunate. AGM batteries are great! You will never have to add water or attend to them much at all. They're about twice the price of lead acid batteries. I don't think you would do any damage by lightly rinsing the dust off.

Thanks. Only had this one since last February. Still on a fast learning curve. Lol. I think the batteries for the motor are regular acid type. They are the ones in the photo that says interstate. Shouldn't have to worry about the water level on these as much.

If you look them up they appear to be FLA but are in fact maintenance free...
