  • Getting more out of the dead battery

    Hey Members,

    I've been using a cheap battery in my Pulsar 150 DTS-i for past 3-4yrs. The battery is long gone now, it barely blows the horn properly, electric start is out of question.

    So, I was thinking about doing some experiments to get the last bit of juice out of this battery before I think about replacement. Here is what I'm considering and I want to know about your opinion.

    > I'm planning to drain the battery completely i.e. remove the sulphuric acid and water mixture from the battery, then refill the battery with acid and water, and charge the battery once again.

    or

    > I would remove half the mixture and add only sulphuric acid till max and then charge the battery.

    or

    > I'll drain the battery completely and add only distilled water considering some acid from the plates would work with the water and further charge the battery.


    I'm strongly considering the first option, however, I ain't sure whether it will work or not.


    UPS Battery
    Also my UPS battery went dead yesterday. I tried to use the battery in Pulsar and voila the electric start was working efficiently. However, I did a fool's job by inverting the battery while trying to push it in the compartment and the battery went dead beyond recovery. Now its useless, else I might have saved some money.

    Do any of you guys have used UPS battery in their bikes, I don't think it has any threats whatsoever. I was thinking about buying two 12v 7.2Ah UPS battery one for my UPS other for my bike.

    Thnx

      well see if the ups and the bike's battery have the same specifications for Ah..else the battery wud not charge properly in ur bike and will drain completely..as for the old battery, drain it out completely and fill it with the mixture taken out of any healthy inverter battery..life wud be infused again in the old battery..i did the same on my bike...works like new..

        When batteries begin to wear out, often it is one or two cells that fail, leading to the battery needing replacement. The electrodes wear out and no amount of replacing the electrolyte will help.

        In any event, this can be dangerous in untrained hands. What volume of H2SO4 will you use? How will you recharge the battery?

        I suggest you go to a battery-wala and talk him into replacing the electrolyte for you and recharge the battery as well. No point in wasting your time and effort on this sort of thing, especially given the dangers involved.

          ya even i would surely suggest u to go to a battery wala coz they have proper tools to open the battery
          and u would hav to work with h2so4 thts a really risky think so i will not suggust u to do so

          or the last option buy a new one
