12 volt battery connections

[Brett Cummins]

Hey!
I'm 14 and I'm trying to power a small neon light that requires a
12 volts of electricity (usually for a car)with a 12 volt battery . I
have an old rechargable battery from a toy car that I had when I was
little. I removed the battery, and I realized that there is a four pin
connecter with four wires leading from it. There are only two wires
going to the neon tube, so how do I do this? Do I only need to use two
of the wires, or do I need to connect the two positive wires together
and the two negative wires to form the two necessary connections?
Thank you!

Hi,
Get your hands on a Voltmeter, or ask your dad for one. Then find out if
your battery gives out still 12 V or more. You do this by connecting one of
de negative leads with the com of the meter and the positive with the
positive from the meter do this for all 4 combinations (naturaly) ... By
this time you will have found out if you need to use all four leads from the
battry or not..... and if the battery is any good .

ps sorry for any typo's I normaly speak Dutch

Hey!
Thank's for the response! I actually have a voltmeter, because
I'm into model railroading. I wired it like you said and set the
meter's dial to 20 DC volts. I get a reading of about 2.80. For a 12
volt battery, I'm assuming that it should read 12. Is the battery
almost dead, or am I reading this wrong? Thanks again!

You could have potentially up to 6 readings. Label the leads, say,
A, B, C, and D. You can put the meter across AB, AC, AD, BC, BD, or CD,
and will have to observe polarity while doing it.

ixTell us those se readings, and it will tell us a lot more about
the battery.

Cheers!

I expect that a rechargeable battery 8 - 10 years old will be useless
after all these years. It will certainly be almost fully discharged
by now, and probably won't hold a charge if you try to recharge it.
