Jared is 100% correct. Very early automotive batteries were made with a porous rubber case that was allowed the electrolyte to leak some, when placed on concrete the moisture created a short which drained the battery. ALL modern batteries use plastic cases which do not leak and thus no chance for an external discharge except across the terminal posts.

The battery sits in an elevated position on a table that just so happens to be wood. Wasn't trying to perpetuate any myths that I've never even heard of to begin with Jared.

The basement sump has flooded in the past; hence the elevated position. And whether or not it's OK, I don't feel good about a battery sitting on the basement floor plugged into a battery tender which is plugged into an electrical outlet.

I use something on Amazon called Camel...... It's a price watcher that you set what you want to pay for it and when it goes down to that price it notifies you..... Pick a couple chargers on it and set it to camel. I've done it quite a few times and have a multitool setup on it that is $103 and i want to be notified when it goes down to $80
Quite interesting on Amazon

Darral - One of the first mods I did when we got our Scamp was to install the Charge Wizard on the Progressive Dynamics converter. Love it, and that I don't have to hunt for another piece of equipment when I put the trailer to bed!

Our Scamp mod list is available here.

Finally put my battery charger on order today. At the beginning of my original post, some suggested checking into the "Minders" and I did. This one would be an overkill for most I know but it had several features I wanted.

Before that, I had actually considered a Schumaker 10030. It has a 100A jumpstart capability. But just TOO many reviews talking about "cheapness" and undependability of it.

I opted for the 12248 Battery Minder. (link below) The Battery Tender put out the most it could at 1.5 A. This one will pump out 8A if you want it to then 4 and 2A. But one thing I read, it will put out as little as 200mA to to keep a battery charged if necessary! Amazing. And it has the standard "maintain" and "Desulfation" features as well. It also comes with the temp sensor which some feel is useless but can be used as a backup safety feature...especially if you're pumping 8A into a battery trying to bring it up quickly. But another feature I wanted it for that I found wasnt available on some of the other popular maintainer chargers was the capability of charging GEL (SLA) cells.

Old John Sch. from Scampers @ Yahoo!! Good to hear from ya. The Wizard is available from Amazon for about 25$. STILL a good choice for that converter. Question though... do you have to plug in the Scamp and run the converter all the time? Or can you simply run a cord to the Wizard and run it independently? I just kinda hesitated leaving my Scamp plugged in continuously. But I think you can prove it hurts nothing!

Hey just went out and looked at your MODS. People here would do well to go out and view your work...it's superb! The door seal got my attention. That's been brought up here too and my buddy from the Piney Rally "TomK" posted a pic of the new seal Scamp is providing now. Looks very promising.

Take care and thanks for posting.

Darral, that's the charger that I used in our 13' Scamp (I had removed the converter when it boiled the water out of the battery, and hummed something awful), and now, in conjunction with our solar controller, in our Lil Snoozy. NO problems with them at all.

Thanks Dave! That's good news as you think enough of it to make a permanent part of the Scamp! Is there anything you've ran into that I should watch for? I've studied up on it pretty thoroughly. The worst thing I read was about the early manual on it. I downloaded a new one that is very readable and easy to understand. But really, I dont see all that much on the charger to figure out. I'm VERY familiar with "smart chargers" in the Radio Control side of life. These are just on a bigger scale.

Another "smart" feature about this charger I failed to mention earlier was, the desulfation technology. They say the "Schumacher" uses "voltage spikes" to desulfate. This BM 12248 (and I'm sure there are others) uses a "high frequency" which is supposedly easier on the battery itself.

Thanks for the encouraging post AND pics!

Darral, no problems what so ever. The only thing I wished it had was a memory as to the settings. Each time it has been unplugged, I have to set the battery type (AGM) +Amps desired mods.

That was one small complaint I had read about which is a non-issue to me. BUT, they (the complainer) didnt understand why it defaulted back to "Gel". The factory stated that the "Gel" default is the LOWEST of charge rates available on the "Minder" which would be harmless to any battery (within its ratings) it's connected to. Like you though, they could have a built-in flash memory...but must have opted out for safety reasons. I'm good with that.
