    Battery Refill

    Ok, so my brother tells me that I can refill my battery with rainwater and put it on a charger and it will work like new...is this true?

    He said while it's on the charger the water turns into the acid etc.. and it basically is like a new battery.

    You have to use dog urine because the acids and electrolyte levels need to be higher than just rain water.

    Maybe. With a non-sealed battery, it's normal for some water to evaporate. The remaining electrolyte becomes more concentrated because the acid itself is not evaporating. You can then top it up with de-ionized water or rain water and restore it.

    This is assuming there is nothing else wrong with the battery, other than low electrolyte level.

    There isn't anything to lose in trying, though, so go ahead.

    I concure with the distilled water for non sealed batteries.

    Dog urine is only good in radiator because it disipates heat very well.....
    A bad day of riding is, still better than a good day of work.

    The water does not turn into acid. The acid is in the battery already but the water electolisises away during charging. The really bad thing about this is that the plates are then exposed to the air. That's why it needs to be topped up now and then if your battery is not a sealed one.

    If it's old and tired and sulphated out then adding water will NOT rejuvinate it. If it's only low but otherwise in fine shape then adding water will let the upper exposed portions of the plates work and that will make your battery seem like new. This is because the water and acid combination is an essential part of both the chemistry of the battery and the electrical path.
    A backyard mechanic without a service manual is just like a hooker without a lamp pole.... they are both in the dark.

    Not only does it work but the battery will last a lot longer. Way longer. Give it a shot.
