Many thanks for your reply; much appreciated!

Hi J.Barry,
You can use the SLA batteries in any position but if they are laid on their side the weight is not evenly distributed. Most of the weight is in the lower section of the battery (when vertical), so if you lay one sideways in your boat you need to move it so that the weight is even, especially if you put one on the centreline of the boat (say over the keel). You can test this outside of the boat.

Hi Colin,

Get well soon!
So that you may be able to go sailing.
This coming Summer!

Cheers, Ed

New knee is healing slowly, but getting better each time I use it, staples coming out Friday. As soon as I can kneel again I will be back sailing again. Great news about the motor Doug.
Cheers Colin.

Exactamente Ed & Colin (How's the k-nee!?)👍👍
BTW; got the brush-gear sorted on your motor, it's running sweetly now 😉

Hi J Barry, most of my larger boats use 12v 7ah sla's I have even used them laying flat and as ballast. Never had a problem with them at any angle. Hope this helps you.
Cheers Colin.

Hi J.Barry,

I run SLA's in my tugboats!
Yes, you can put them in any position!
They are sealed and there's no liquid in them.
The batteries are sealed electrolyte-tight, immune against installation attitude they are solid!

Cheers, Ed
