Its Great When You Can Take the Battery OUT of your Bike and Take it around... and Then Leave it for a few days on a Trickler ... THEN you have to Put it on a Tender... and STILL Hope it Works the Next WEEKEND you Ride... BUT, if You Have to Ride your bike Everyday and are Expected to Be Where you NEED to be, Then Just Buy a New Battery... $80.00 Bucks and You aren't Messing around with all this Drama.

I left my ignition on a couple of years ago and thought I'd ruined my battery too. The battery tender wouldn't touch it, no way. I went to NAPA and bought an actual battery charger for marine and motorcycle use. 24 hours of slow charging brought it back to life and it's still in use today.

 

See post # 15. He's past asking for charging suggestions. He had it charged & it wont hold.

He want's to buy a NEW battery.

 

There wasa debate on here recently and most people have agreed that the BEST battery is made by Kodiak/Odyssey. I found this to be the best price which is not all that much more than an HD battery.

Well I got the new Ultra in July, left the 2006 Dyna sitting in the garage until 2 weeks ago, I tried to crank it and nothing. Checked voltage it was 6.5v. I hooked up 1.5amp charger for a week, then onto tender for the weekend, got it back up to 12.5 volts. I started up the bike , but it was a slow crank, like the battery didn't have enough capacity to get the motor spinning good. So , I used one of the on-line HD stores for a 20% discount + free shipping and now have a brand new HD AGM battery for $84. Not worth worrying about being stuck on the side of the road with a EFI bike and electric fuel pump not having enough battery to get it going.

 

Wise move and great price for a replacement battery but my standing line is you get what you pay for and I am too poor to buy cheap stuff. Not criticizing at all but here are the specs for the Odyssey.

PC 925LMJ Specs:

• 925 cranking amps for 5 seconds
• 870 cranking amps for 10 seconds
• 765 cranking amps for 20 seconds
• Short circuit current over 2400A
• 28 amp hours
• 50 minute reserve capacity with 25amp load
• Female brass terminal w/M6 SS bolt
• Measurements (for Harley mounts):
• Length 6 5/8"
• Width 4 15/16"
• Height 7"
• Weighs 25.5 lbs

Odyssey design:

• Rugged Drycell sealed design
• Military grade
• Vibration resistant
• 60% more starting power
• Deep discharge reserve power

I have mine hooked up to the new optimate 4 and it really is the business. I have killed two scooter batteries through allowing them to discharge over winter and at about €60 a pop, my Optimate was a bargain at €65. (My Ultra is permanently hooked up to this)

The new 4 has a bunch of lights / charge rates and a diagnostic mode for your battery and it brought one of the previously "dead" scooter batteries back to life. Failed on the oldest one though, but this one had been idle for about 3 years so no real surprise there.

Hope this helps.

Two excellent articles relating to battery charging and the merits / de-merits of different types of battery here:

Have a read and you'll see the reason why I toasted the two batteries.
