Knowing voltage and current readings would go a long way to find the cause and a successful repair. What is charging voltage with no fans or brake lights on at idle and 1800RPM ? What is voltage reading of battery when parked and after sitting two days before trying to start? Can the battery pass a load test after charging? And what is the mA current draw of electrical system on battery?

Why did you have to charge the battery after returning from Florida?
Had the bike been ridden lately?
Was the battery dead?
What is the age of the battery?
Have you had to charge it to start the bike in the past?

If the bike had been parked for two weeks and the battery voltage was down below 10 volts before you started to charge it, I'd say replace the battery. It will save you a lot of trouble.

I suggest you first take your fully charged battery to an auto parts store and have it load tested. It sounds like you may have a battery problem. Then check how much the charging system charges.

Those who say it cannot be done should try not to interrupt those who are doing it.

I usually charge both my my and lawn mower.
Battery is 18 months old. It’s a Duralast Agm from auto zone.
I want to ride it but won’t stay charged up. Yes, I have had to change it before I rode. It’s on an overnight charger. I unhooked all of the petty accessories and will see if that helps. It’s a ‘97 with under 59k on it.
Thanks for the replies. I’ll keep all of you posted.
Ride safe!

Well, with any vehicle or piece of equipment, if you have a good battery, properly working charging system and no unusual power drain, you should not have to charge it all the time. I never charge my lawn mower or bike and they always start right up.

Do you have a warranty on that battery from Auto Zone? If you do, I'd take it back and get a new one and while there, pick up a Battery Tender.

I have two motorcycles, a lawnmower and a GMC truck.

The lawnmower and GMC truck see little use most of the year. I keep the lawnmower battery in the garage and on a Battery Tender.
I keep a Battery Tender on the GMC truck because I don't drive it but maybe every other month and when I want to drive it, I like having the battery fully charged.
I keep the a Battery Tender on each of the motorcycles because I can only ride one at a time and I may go a week or two and ride only one of them.

It only take a few milliamps over a period of time to drain a battery down to nothing. I found out the hard way with a Yamaha Virago I had years ago. I had an aftermarket radio with a clock installed in the Windjammer fairing. That little clock in the radio turned that battery into a sulfated brick in a mater of months since I was not smart enough to even own a Battery Tender. Luckily, that battery had a 12 month warranty and I was able to get a new one at no charge.

Think abut it, a 20 amp battery with a 24 hour a day 50 milliamp drain will only last 400 hours. That's about 17 days.

What charging device do you have, and what at what amp does it charge?

It is a Schumaker (?). I had an led clock and a cigarette lighter wired in to a fused panel.
I unhooked them. Ill see how everything goes in the next few days. Fingers crossed.

It is important to know the charging output amperage of the charger and the amph capacity of the battery. For example, if you charge a 20ampHour battery with a 1amp charger you will need 20 hours to have a fully charged battery, if there is nothing wrong of course.
Also, sometimes it can be difficult to recover an AGM battery if it is discharged below a certain voltage (10volts if I remember correctly).

What you are saying is completely out of my league. Maybe I could reseach all of your info to determine what equipment etc I need.
I have completely stripped all battery attachments from the battery. When running I get 14 plus volts.
Im looking at maybe buying a newer bike (trike). We will just have to wait and see.
Thx for your reply.

You should not be running it with the battery disconnected, are you?
