Thanks Guy. Any recommendations for a battery? The wall-wart charger I have for it states 12v-400ma over a 24hr max charge.

I know next to nothing about battery technology. I was happy enough with the battery (when it worked!) for lighting clusters and copperheads - I think that I would still like something that can put some fire behind some clusters.

Frank has already responded with the link to my go to recommendation for a battery. Taken care of, it should last many years and is at least twice the battery that you were using.
A good rule of thumb for battery charging is to take the stated capacity and divide by 5 to 10 for the charge rate. So for example, the newly recommended battery is a 5 Ah battery, so a charger that can charge at a 500 ma to 1000 ma rate would be about right. The faster you charge, the more heat generated in the battery as it charges. Heat is an enemy for a battery's longevity.
BTW, I just checked the battery on the charger. Even though the analog meter for the charger says about 2 amps, the battery is not getting warm at all, and I suspect it is not really getting much if any of a charge. Also, analog meters on dumb car battery chargers are not all that accurate.

Guy,

Thanks a lot Guy!
That plug was a cheap one that I probably got at Walmart. Thanks for replacing it. I knew the screw was stripped, but didn't even consider that that was the he problem with the beeper, again ,thanks.

I just took my charger out of the box and actually read the directions.
I ended up getting the NOCO Genius 1 charger from Amazon.
It is a 1 amp hour charger which is what I used to use for my motorcycle batteries. We used to call it a trickle charger.

The battery is 12 volt AGM, whatever AGM means.
What I like about the charger is that it has several LED indicators.
Right now the charge LED is pulsing green which means "Battery charge complete, optimizing battery for extended life"

Here is the URL for the charger on Amazon.

Google is your friend:

An AGM (absorbed glass mat) battery contains a special glass mat separator that wicks the electrolyte solution between the battery plates. This material's design enables the fiberglass to be saturated with electrolyte – and to store the electrolyte in a “dry” or suspended state rather than in free liquid form.
