    I was going to add battery's to my house for emergency power, I was told that battery's will creat a gas and you should not charge them in the house?

    Depends on the batteries. If you go with a dry cell type no gases. But yes most lead acid batteries will bet gas.

    And isn't hydrogen gas generation the reason you connect the ground AFTER the positive when giving a car a jump, so as not to generate a spark at the battery that could make it explode (including with very strong acid all over you)? 'course!

    What kind of batteries, and what kind of system? Large batteries are way expensive, and won't last very long. How about a generator?

    YES! Had one blow up on me yrs back while doing a gud deed for a lady who didn't even thank me or offer to buy me a new shirt 'n shades :mad:

    1. Charging a traditional lead-acid battery DOES give off hydrogen gas. You want to have adequate ventilation for that. If you have ever been in a golf car barn, where 25-50 carts are charging at one time, you might notice the BIG gable vents! Keep them away from sources of ignition (cool and dry is good)

    2. Jump starting a car- hook positive to positive. Hook negative of GOOD battery to some solid metal part of the car with dead battery- but NOT to the battery. When you make the last connection, you WILL get a spark. You want that spark to be away from the battery.

    3. Emergency power- depends on what you want to power, for how long. I have 4 ea 115 amp hr deep cycle batteries, and a 2500 watt inverter. I can run smaller items for quite a while before I need to recharge batteries.

    C-3 gives good advice. There are ways to put them in your house safety (Vent hoods) that is usually as part of a larger system supplied by an alternative source like Solar, Wind or Hydro. If you move the Batteries outside in a shed (that has AC Power), put it as close to where your going to need it as you can, Distributed DC is high loss even on large conductors and their is still a large enough loss on longer runs using an AC inverter.

    Anything of any size (2000 Watts) is not cheap and the chargers/ inverters alone can go many hundreds of dollars if not thousands. Battery backup is tricky if you want it to work, it has to be maintained and used regularly. Our University goes through very expensive batteries in our huge UPS's like crazy because the batteries are not worked or maintained properly. Even well maintained batteries have a certain life-cycle then they are recycle material.

    Never seen a spark this way myself (only on positive posts) but, yeah, the negative on "chargee" should be to the frame of the car where everything else is also grounded by the way...

    Hoss, glad u were wearing shades!

    Yes they do pop.Back when I first started turning wrenches one blew on me putting a volt metter on it.Spent a few hours in the er washing out one eye.

    You may want to try a company out of Florida for some of the least expensive solar panels out there.
    The also have information on all sorts of alternative power.

    I dunno, I went with a company that got hundreds of millions in one-time stimulus money by this Administration (which they then built in to their annual budget they never actually submit to Congress). Solyndra. What could be safer? But I haven't gotten my order and they aren't returning my calls...

    What I need the batteries for is my wife's oxigen condenser. A generator could work the problem is she could not work it if I am not home. With havering a battery system she could have power till I get home. Will need to run 600 wots.

    600 watts is 50 amps on the 12 volt side. Maybe 1 to 1-1/2 hours run time per fair sized deep cycle battery.

    Your concentrator runs on AC, right? You will need an inverter to change DC in the batteries to AC- and 600 watts is a pretty stiff continuous draw. Since there are losses from the inverter, as the man said- about 1 to 1.5 hrs off a typical Marine deep cycle battery that is FULLY charged (don't even think about a car battery). You may be better off with a decent sized oxygen tank for emergency use.
