The Yuasa YB7C-A needs replaced in my 2009. I like the idea of using an AGM. Is there an AGM battery that equals or is better than the OEM that will fit the battery box? Thanks,
Replacement Battery

I got a YTZ7S AGM battery on ebay from this guy a couple months ago for the '95 and one a year ago for the '08. I never had any problems with it....but it's only been a year. I really like that there's no more leaking when I tip over. I think a lot of them are made by the Chi-coms in the same place and branded by different companies. It's a little smaller than the original but I cut pieces of foam to fill the space.

The YTZ7S is the one I thought was close. I just wasn't sure about the amp. hrs rating being less than OEM. Sounds like it is working for everybody.
What's your thoughts on Yuasa vs. aftermarket? I don't have the kick starter and do ride into places that would not be good for push starting, so the best battery is essential.
I pulled the OEM battery to see if I could fit the Odyssey (not) and decided to hook it up to the Battery Tender while out of the bike. It charged up (solid green light) and started the cold bike like it was warm. It started up this morning again, but not quite as fast. I found a blown fuse in the Battery Tender plug (SAE) and now I wonder if the battery needs replaced at this time. I'm likely to find out somewhere that will make me wish I had replaced the battery or bought the kick starter kit. On that subject, can you tell me about installation of the kick starter kit? Can I, a halfast wrench, get it done right? Thanks Again,

Why do you say your battery needs to be replaced?
A fully charged battery has 12.6-12.8 V at rest. If you measure the voltage at the terminals and charge it fully, the only way to know if it's any good is to get it load tested. Any garage or battery dealer will do that for you for free because they would like to sell you a new battery,
Be forewarned - if you do buy a new AGM battery, YOU have to charge it up completely before first use otherwise it will prematurely fail and never hold a full charge. Do not rely on the guy in the store telling you it's good to go when you buy it, just hook it up and ride. If it's not fully charged before you try and start the bike with it, it may only last for a few starts and then crap out and you will be replacing it real quick. Like I said, YOU must take the responsibility and fully charge it before you use it and then it will last for many years. This comes from the instructions included with the battery and from Yuasa themselves.

I just replaced the battery in my 2008. I went this route:

I had to put slight bend in the neg cable connector to get it connected to battery terminal. The new battery is a lot smaller than the OE battery so I used pieces of cardboard to fill in the gaps. Works great.

Motocross is a battery that is made by Yuasa also.I'm still trying to save up the cash for the kicker ( Bay Area Yamaha....North Bend, Oregon)....from what I've read,yes you will be able to install the kicker yourself.There is a "sticky" on this site about the kicker install!.

Yea, maybe I jumped to conclusions, but I've had no starting problems, ever, and one day, there wasn't enough battery to turn it over, so I "ASSUMED", because of the age of the battery, that it was time for it to go bad. I have since fully charged it and all seems well. I will see if I can get the battery tested somewhere. I still don't know why the bike wouldn't turn over that one day, but I'm sure I will find out soon enough. I hope to get out tomorrow for a few hours, so I may have an update tomorrow evening. Thanks for the charging info and all the battery advice, also.
I decided to go right to the Shoai lithium Ion battery fro Procycle and have been very happy with it. It would crank the motor over on a very frozen morning just the same as a sunny day.
It was more expencive up front but will pay for itself in the long run. I did purchase the kick starter kit from Bay area Yamaha but I won't install it untill I do the lower cylinder gasket replacement.

I did get to ride Saturday. About 70 miles on a real mix of terrain. The battery did it's job. I even drowned the bike in a creek crossing and the battery held up through the restart ordeal. Maybe I had a bad connection and corrected it without knowing by taking out the battery to measure the battery box. I would like to know more about the installation of the kick starter. I would like to add the kick starter to make the T-Dub even better. Thanks to all for your help.

Glad it's fixed. plus you saved a lot of money.
Clean off your battery terminals and make sure they are tight. Sometimes with all the vibration of riding around, one can get loose and if you have a poor connection, the bike may not start.
Also get yourself a 1.5-2 amp battery charger and they usually come with a pigtail connector to leave attached to the battery hanging down somewhere protected underneath the bike. Then, whenever you need it, you just plug in the charger to that cable instead of having to remove the seat to get to it. You can also use that connection and cable for a GPS, cellphone, or some other low amp gadget.

I bought 2 of these Golden Dragon AGM batteries for my TW's.

I took some picture to show the size difference from stock. I stuffed a rag between the batt and the box to keep it from rattling around.

Back to the Kick starter for a minute;
Is there installation instructions anywhere that I can look at before I buy? I would like to feel confident that I can do the install correctly. Thanks

Has anyone tried a YTZ10S AGM battery?
It looks like a higher amperage version that is still a little smaller than OEM, so there should be no fit issues.
it is what I am running on my SV650 and I would love to commonize so I have options if one suddenly fails.
