Flat battery?

[neels]

One terminal off is fine.

[shafty]

ok so I've disconnected the negative terminal but these pricks that installed my new battery have tightened the screw on the positive terminal so tight its not budging ! to the point where i've almost burred the head of the screw trying to undo it.

Just wondering. Is it ok to try and charge the battery with the positive terminal still connected?

Same happened on my Wifes Honda Shadow - a tickle with an impact driver worked. ( You'd get new screws with a new battery btw)

Might be old fashioned but a dab of vaseline on the terminals when finished is a good idea. Keep us posted.

Thanks fellas. I finally got it off. with one fatigued forearm and one burst blood vessel later.

You can use a penetrating lubricant, like CRC or WD40 to loosen it.

You can charge it with one terminal disconnected ok.

to anyway gezz i use impact driver for this very reason just tap should budge it
The old jap engine cases used philips bolts what a pain well erly honda singles did
Just wondering. Is it ok to try and charge the battery with the positive terminal still connected?
why whould you want just undo it oh yeah the bolt well take out the main fuse if theres on the main red power cable out
Other wise spray little crc screw cant be that bad how hell can torque a philips screw bolt oh yeah shold be nut
on the other side udo that way holding screw head in the other end

Neels... is a lead acid what you would call the dry cell come jell battarys of today?

well?

You can charge it with one terminal disconnected ok.

even if its the positive terminal conected? I would have thought the current would still flow through the wiring system? just cos the battary is de earthed dosnt mean the bike isnt?

[sleemanj]

well?

A lead-acid battery usually refers to a wet cell battery, as in, liquid acid.

Technically a gell, or dry (eg AGM) is still effectively lead and acid, just not liquid acid any more.

even if its the positive terminal conected? I would have thought the current would still flow through the wiring system? just cos the battary is de earthed dosnt mean the bike isnt?

There is no circuit with one end disconnected. An electrical system requires a circuit, from positive, through stuff, to negative. Since the negative (or positive, or both) of the bike is not connected to the charger, there is no circuit and no flow of current.

Thank-you all for your input. Currently charging along quite nicely. Must nearly be done because its been 6 hours now and the light hasnt come on yet, to indicate that its fully charged. Its says to expect 5 to 10 hours of charging time.

which is what I thought... just that a LCB was mentioned in page 1 and I was thinking havnt seen one of them in a newish bike for yonks... so does the 1-10ah charge thinga me still apply?

[sleemanj]

so does the 1-10ah charge thinga me still apply?

I'm probably not the best person to be asked that question, I'm so lazy that I don't bother disconnecting either terminal for a charge and use whatever charger I can find at the time (currently a red shed one which I've managed to hang onto for a while now without one of the siblings wandering off with it...)

But in an ideal world, yeah probably 10% would get you the best charge - but in the real world more than that is fine as long as you don't go so very overboard that you are cooking your battery.

Lead acid chemistry batteries are pretty tolerant of abuse, which is good for lazy bastards like me.

In an ideal world, every bike would be running a Shorai battery...

hey guys just another question. Will the battery re-charge fully while riding it?

Its been 10 hours now and, although the green light hasnt come on to indicate that the battery is fully charged, the battery is making that bubbling/fizzing noise.
I figure that if the battery is charged up enough to get the bike going again will it recharge fully if I just put it in and ride it for a while?

Update : put it in after 10 hours. lights lit up but wouldnt turn over. Put it back onto charge. Im guessing i have to wait another few hours.

No. The bike's designed to maintain the battery, not charge it.

Every bike's different, some can pull a battery up from lower than others but I'd leave it until the charger tells you it's finished mate.

"Power" only flows where there is a difference in potential.

If only the positive terminal is connected to the bike, then potential difference between the positive battery terminal and the bike is zero - no current will flow.

If you attach a charger to the battery the potential difference between the bike and the battery terminal is still zero.

You can verify the potential difference is zero by measuring the voltage between the only remaining connected battery terminal (positive in this case) and the rest of the bike.

Thanks for that. Yep ive put the battery back on to charge. Was just worried about over charging it. It is a cheap warehouse job recharge kit.
