When I first received my 130SLT (in Feb this year), I loaded it up with the necessary AA batteries. The following week I bought the AC converter and have used it ever since to power the scope. The batteries are still in place. Is it best to leave them in or take them out, now that I'm using AC power? My concern is battery leakage as they age.

What I would do is about once a month turn on the mount with battery power. Just enough for it to get to where it wants you to start an alignment. Then turn it off. What happens to most things that use batteries and sit, they leak because of none use. If you turn them on and let the electrons flow some, they will last longer and fresher. Also, no battery leaks. I do this with all my flashlights I have stored all over my house.

Once the batteries are fully exhausted they are way more likely to leak.

I have seen dozens of items with battery holders and even the electronics ruined from leakage.

One of the good things about those awkward external battery packs of some scopes is a leaky battery can only ruin the holder,not the "works" inside the scope.

And the cheaper batteries are more likely to leak sooner.Happened here too often not to notice.

Batteries demand regular inspection.

I don't have an SLT--I have a SE. But the SE has 8 internal AA's.

I put in AA's, but always power from an external source. The internal AA's are there in case I need to quickly disconnect the power cord & reconnect (I have cord-wrap turned off).

About every 2 years, I replace all the AA's. (I suppose it really should be every year, but my scope is stored indoors, in air-conditioned space, etc.)

True.. But if you test them on a regular basis, like I do with flashlights, you can see when they become weak. That is when you would replace them.

Once a year on New Year's day is good practice.
