Portable Battery Charger

All - After realizing that the house batteries were down below useable when went to get MH from shop, I got to thinking that maybe I should be carrying a portable battery charger.

Since there are a variety of battery types in use, and I have the Lifeline AGM's, I was wondering if anyone carry's a portable unit for those times when you need to boost up the coach starting batteries, or your toad battery.

I am leaning toward the Schumacher PSC-12500A model. It has a 125A boost starting, and 40/15 amp 12VDC charging, and is 3 stage type. It has an AGM setting as well.

Any thoughts would be appreciated.

What I carry is a 1000 peak battery amp/500 starting amp battery power pack, it also has a small compressor.......great little backup for when you or someone else needs a jump without you having to drag out the jumper cables.
If you are staying in one place for a period of time, or like I do when I store, is I have a 10 watt solar panel that I have wired directly to my batteries.....I just lay the panel on the roof with suction cups and they stay good and tight.

We carry a Schumacher charger - don't know the model number - it is a small portable with capability for charging different kinds of batteries. I used it when our convertor/charger was out for about a month to keep batteries charged and use it to charge chassis batteries when we are parked for a couple months somewhere. I have also used it when some dummy left the towd in ACC overnight (guess who?) to recharge the batteries. IMO, too cheap and small not to carry at least one.

I am thinking I should start carrying my battery charger with me as well. Never had the coach batteries go down but have had problems with the car battery after towing for several days. ( I am looking at the Toad-Charge to fix that problem). Your AGM's are just sealed wet cells (SLA) so you can use any charger you like. Being deep cycle they can accept a high initial charge so 100A (like your coach's inverter/charger) would be fine if you need to recharge quickly. I also use a solar panel to keep the batteries topped up in storage, but you have to be parked outside to do that.

Ok the Schumache it is. I can get the one I want from amazon at 112.00 so that is where I will get it. All the other places wanted more. Nice it's made here, instead of china.
