free stuf

Pete-

If you really want some free stuf, and all you have is lights to run, just watch for junk batteries at public dumps, transfer stations, behind service garages, etc., and take your voltmeter. Lots of batteries get discarded because the owner deemed them not suitable for HIS purposes, but they might have plenty of life for YOUR purposes.

The nice thing about free batteries like this is that you can abuse them without a guilty conscience; you know, like running down a starting batt, replacing fluid with tap water, etc.

Pete

free stuff

Pete,

I like it! I'm going "shopping" this weekend.
I will have to blame you though, when the wife asks why I have brought home all these batteries.......

Jump it installation

The best deal I found on a Jump it was at Costco; $50 (with rebate) for a well built unit with light and 200 psi air compressor. I solved the installation problem by installing a quick disconnect battery terminal ($6.95 at NAPA) on the positive terminal of the house battery. When I want to use the Jump it I just remove the quick disconnect from the battery, put the positive clamp from the Jump it on the quick disconnect, put the negative clamp from the Jump it on the negative terminal of the house battery and it is complete. No switches, no plugs, no extra wires. The advice given here to not hook power supply units in sequence with the house battery was good. Thanks.

Free Batteries

As I was driving around the back of various places looking for old batteries, the wife got suspicious and asked what I was doing.:o
I had to explain.....

She said why not just buy a new one? :omy

She just doesn't understand....:sad


Due to the EPA's dilligence in this area, a used battery is a rare find, all the more reason to continue the hunt.
:laugh

old batteries

Pete:

Not to spoil your fun, but you might find an old battery, take it home, charge it up, and find that it'll put out 12 volts and shout 'whatta deal'. However, if you'll check each cell with a hydrometer, bet you'll find at least one cell thats weak. This means you'll run outta juice real quick. The battery will have something like a 10amp/hr capacity when 'fully charged' instead of 85amp/hrs like it did when it was new (and the voltage will be lower). These are the kind of batteries that might start a car as long as it will fire up on the first crank but if you have to grind a while, it'll give up, won't hold the charge.

Not much to rely on!

When shopping for 'jump-its' check the amp/hrs. They seem to range from 10 to 18 amp/hrs.

P.S. I also love the thrill of a good 'curbside' find....bicycles, wheel barrow, vacuum cleaner, even a pedistal type dining table, etc, etc.

Jump-Its and jump-its

Many recognizable brands, many generic or house brands, many capacities.

It appears from posts that you all are having satisfactory results both from generic brands and more-expensive name brands. When I look at these devices in catalogs, such as JC Whitney, in X-Mart, Sams, AutoZone, etc. the main difference seems to be capacity (amp hours) and the resulting weight of the higher-capacity ones. I presume that bigger is better, not so? Personally, I'd prefer lighter and smaller, 'cause we try to minimize what we carry along with us. (Our dogs require all the space that's available.)

Also, these seem to be sealed lead-acid devices. Does that mean that the life expectancy of a jump-it would be 3-5 years?

(B.t.w., Charles, I had a catalog the other day that had 3 of them for $99--sounds like a deal made for you. And, C.W., yes we do have a gen, but prefer to leave it and the gas can at home unless we are boonie camping.)

This is the only battery we need for lighting. We camp in a pickup. True, we will need more power once we have a trailer, but this works fine for now, and is a good adjunct in a trailer as well.

It is a 7 Ah AGM, available at any battery store for about $25. The three-stage charger will set you back another $50, but they last a lot longer than the battery. If you already have jumpits, use the jumpit charger.

The light bulb is a 15 watt DC compact fluorescent, purchased from Real Goods for $12. The drop light is a pretty standard item, of course. For plugs, I use 125V twist-locks, because I had a good free source of these at one time, otherwise I would suggest SAE plugs. I use a 10 A type ATC fuse.

This setup is used mainly for cooking dinner on the tailgate, setting up camp, and for finding stuff roadside. It is too bright for a "bedroom" light, especially when compared to starlight (our favorite situation). It will easily last three nights of normal use, and usually we are able to plug in sometime before that.

We used this light a few weeks ago to assist another motorist who had hit a deer. Having a completely portable 900-lumen light source not only makes unbending bumpers and changing tires much easier, it also makes it much safer if you have no choice but to be 20 inches from 70 mph traffic.<img src=http://www.fiberglassrv.com/board/uploads/3df40781bec6612vlite.JPG/>

Also I have this cool solar lantern. I don't like to shell out big bucks for D batteries to run lanterns. This one is very lightweight. I leave the solar panel on the dashboard. The only problem is that when road atlases and things are shuffled around the cab, it sometimes comes unplugged.

It is very durable, and there is a low-voltage cutoff built in, to save the ballast and tube.

Aux Battery Power

I've been looking into jump-its and just about decided that it wouldn't hurt to have one on trips. I started looking into the different ones available but since I don't really need one with an air pump (I already have a 12v pump) then I guess there's not much difference. I love a bargain. However, I have also discovered that although more isn't always better, less can be disappointing at best and more costly in the long run.

I ran across this thing at Camping World. I know I could buy three for the price of this one, and I know that it is probably heavy, but my question is: Is it good? How does it rate compared to the less expensive ones? If I don't own an inverter, wouldn't it be better to buy this one and not have to buy an inverter (I know, I could use an inverter on any of them).

Are there any advantages to something like this other than making my wallet lighter to carry?

Rechargeable XPower Portable Powerpack

Thanks.

Another advantage?

If I am understanding what I am reading, then I could have a less expensive unit as a secondary power source to this one. That way, I could still use it as an inverter, right?
