Hi Lew,

Thanks. I also forgot to mention that there was shipping on top of the above prices.

OW.

I replaced my battery this year with a grp 27 lifeline AGM from batteries plus. It was a little over $200. I went with the grp 27 because the battery compartment on my 75 TW.

Sometimes it even dribbles out the front of the battery compartment causing a little corrosion. Am I over-filling? Batteries are not “boiling.” I still have original uni-volt.
· If I am not running the fridge (plug it in a few days before a trip) I unplug the shore power and run off the batteries (just a few lights if we happen to go inside). I do this as I understand the uni-volt is not the best charger and don’t want to boil the batteries. Is this good practice?
· Is it worth switching over to AGM’s if I still have the uni-volt? Or is that a waste of expensive batteries?

Thanx, Bill
Any ideas about my persperation issue?
Lew?
Is this typical with uni-volt?

Thanx, Bill

Bill, the Univolt is a relatively unsophisticated charging device, and my Univolt used to cause considerable fluid loss from over-charging. This caused the perspiration on the top of the battery. I replaced mine with a multi-stage intelligent charger (Intellipower), and this perspiration no longer occurs. The change to an Intellipower was well worth the cost, as it was much quieter, more efficient, and the batteries required much less topping-up.

Thanx Nick, that is what I suspected.

Am I right to unplug when at home?
This should minimize any damage due to the uni-volt over-charging?

Just curious...about how much to switch to Intellipower and does it fit in the same space?

Bill

Hi Bill,

Nickcrowhurst has it right. The old Uni's were good in their day, as it was all they had. A new converter with 3-stage charging (WFCO) or with added compensation for battery temperature (Parallax Temp-Assure) will not eat your batteries as they will be properly charged with the last stage being a float or 'trickle' charge that will simply keep them topped up.

That said, I would NOT leave the trailer plugged in as the old Uni WILL overcgarge the batteries every time. If you want to keep the batteries full, get a quality 3-stage charger ($50-60) and charge the batteries directly.

This discussion and folks experiences with the Univolt now makes me wonder.

I have a 71 and the trailer was worked on in early 1990's by Airstream - new furnace etc. The converter was changed so it is not the original Univolt but I presume it is still a Univolt. The battery has been in the trailer for 15 months. I leave it plugged in and have never yet had to add water to the battery.

Was the Univolt still being used by Airstream in the early 90's - were they improved by then?

Thanx Lew and Nick, I bought new batteries last year and they seem to be holding up well with my current method; when I return from a trip I plug in for a day or two. Then the camper sits for a week or two with just battery power, but very little use ( a few lights when we start to prepare for our next adventure) and then I plug in again for a day or two before we leave to cool down the fridge. For the time being (untill we can get a better charging system) is this a good method of living with a uni-volt? It seems to be working...am I kidding myself?

Should a better charging system go hand-in-hand with AGM batteries? Or does that negate having to buy more expensive batteries?

Just trying to plan the budget for next year...

Bill

Bill, the Intellipower (incorporating the Charge Wizard) fits in the same space as the Univolt. They are available for under $200, from Camping World, and was it Overlander63 who had a good deal on them? Someone will let us know.

Hi Nick & Bill. It's 68 Overlander -- his business link is at this personal profile page. Do more research here on the WFCO units -- they're a step above Intellipowers from what I read.
