Battery. I am beginning to think charging is bad?

[mrbyber]

I posted in a thread in the early winter saying I would post this in the spring.
Well,
I took my battery out in November and put it on the laundry room shelf and there it sat until last Monday. Took it to the dealer and they tested it. It was fully charged and in perfect shape. I have started the bike a lot this last week with no problems.
As I said last fall, My boat mechanic swears that any type of charging will kill your battery in a short time. He described it to me as an "un natural charge"? What ever the hell that means?
I have never charged my boat batteries in the winter and have had no problems. Going on 4 years now with those. Every single person I know with trickle chargers need new batteries all the time. Just like some of you.
Just something to think about.

Now I don't know shit about batteries but I do know mine never die and I don't charge them in any way!
I will probably buy new boat batteries this year and a new bike battery next year.
Don't want to push it.

You may be right, I don’t know. This is the first bike I have ever had a problem with. I have always left my battery in the bike over the winter. Usually could get 3-4 years out of em.

Byber take this for what its worth. I was having hot start issues at the end of the riding season last year. Over the winter i would let it idle until the fan kicked on or about 20 minutes once a week. Im too cheap to buy a trickle charger. It would barely start and would reset the trip odometer and clock every time. About 5 days ago it finally didn't have enough juice to start. I borrowed the neighbors deep cycle charger that he bought for his boat motor and charged it for about 10 minutes. It now starts just as lively as when it was new.

Im no battery expert but maybe these trickle chargers just aren't cutting it? I'll get the specs of the charger in a couple of days if interested.

Hay JATO, with the charging system on the Fury, running it at idle does not charge the battery at all, just riding at speed or at highway speeds. What you are doing is just running down the battery every time you start and just run at idle. Finally, there is just not enough to start.

if you're odo resets then you're just prolonging the obvious:
you have dead cells.
recharging gets you going for a while but your electrical system is now subject to short circuits as the cells degrade.

get a new battery.

It was my understanding that the charging system kicks in at above 2K RPMs, at least on VTX bikes. I could be wrong, but this number really sticks out. Running idle wouldn't charge the battery though.

Running at idle will provide the slightest charge, mostly to sustain running. Higher RPMs=better charge. Your best bet for a battery is to let a low power system charge it, High amp chargers= bad, low amp= better. but with charging off the stator you have probably the lowest load going into the battery allowing a more true/safer charge.

when charging, your battery will heatup causing a breakdown of the materials inside keeping temp as low as possible will get the best and safest charge. I read somewhere our bikes take like 2 hrs at highway RPM's to produce a full charge from dead

I hooked up a volt meter to my battery at idle and it shows 14 volts. I don't know much about batteries or charging systems, but it seems to me that it does charge at idle. The problem is that your bike will overheat before it is fully charged again. I worked at a motorcycle shop for about 3 years and the mechanics and owners swear buy them. The right trickle charger senses when the battery is charged and stops. I do not recommend just letting the batteries sit, hooked up to the bike or not. Yuasa Batteries :: Battery Maintenance

2 winter and on a tender the whole time. not 1 problem

my 2 bits, crumbles, whatever

it may show 14 volts but amps charge the batt.
