Ok, I've a bike which i suspect is overcharging. I have 2 add water
to cover the plates at least wunce a month If i replace the normal
battery with a sealed does that mean fit N forget ?

No, you really have to fix the problem. You cannot buy a battery to fix your
overcharging problem. Have you checked the voltage?

no, not yet but with modern solid state gear its repair by
replacement isnt it ?

Sure, but the likely replacement part, the regulator, is around the price of
a decent battery. You don't have to replace the whole bike. Measure the
voltage.

Ok, that's not good. As per the other posts, you need to check the voltage.
While the bike is running (idling obviously) go out for a ride for a few
minutes to ensure it's stable, then come back in, and while it's idling, check
the voltage.
If your bike is anything like mine, there is no easy access to the wiring or
battery while it's assembled, so you'll have to makeshift some wires
beforehand to make it easier.

While idling or revving, expect no more than about 14 volts. Any more than
this, you have a regulator problem.
The other posts have pretty much nailed this one, but mine is the long answer.

If the regulator is stuffed, replacing the battery will NOT fix your problems.

In my case, it failed suddenly, so I didn't coin in on the fact till it was
too late. The regulator was outputting too high, blew two bulbs (headlight
and tail light, the two that are on all the time), then proceeded to blow the
ignition unit - so no worky.

Of course, I didn't notice the clues till it was too late, about an hour out
of Leongatha, which is two hours out of Melbourne. Considering I live in
Sydney, it was not a convenient place to fail...
Oh, and a shameless plug for Leongatha Motorcycles who were generous about
the situation, and brought their ute over to tow my bike back within a very
reasonable timeframe.


If you were to replace with a sealed battery, and still have a faulty
regulator, you will kill the battery, with no chance of saving it again. And
as with my case, it's possible the battery is not the only thing you'll end up
killing.

Just to stress again, at the very least, if you don't have the means, have
the regulator checked by someone else who is capable.
At this point, from what you've described, the battery should be the least
of your worries.

Look past the marketing-speak, and consider that a "sealed" or
"maintenance free" battery is really an "unmaintainable battery"...

So no, buying a battery that doesn't allow you to add water when needed
is _not_ going to fix your charging circuit problem for you...

You'll have to split the cases.

their are benefits of them, most maintenance free ones are AGM, do a search
on wiki for it, gives them a good write up. the best thing is they can be
stored at any angle, and be placed in hard to get at area's. which is why
they tend to use them in modern bikes. I found them better with cold
cranking amps which is a must were I live.

fix ya bike though if its broken, band aid fixing it isn't going to fix it.

If you can diagnose the problem and fix it now, it may well save you a
small fortune.

I had a regulator/rectifier go in the Suzi. I didn't know it. It
overcharged the battery to the extent that it dried it out, Battery
shorted out. Stator burnt out.

So - instead of just replacing a R/R ($200), I had that, plus a battery
($100) plus a stator rewind ($300) and that didn't include the cost of
doing the work to take old stuff out and put new stuff in.

Or Suzuki.

Oh I'd say 14.25-14.5 V as an absolute upper limit may be acceptable with
the headlight off (if possiable)

I was wondering when the "split the cases would come in"
The old trustee owner of a multimetere will sort out the cause.
