It will be time for me to replace the battery in my 2009 Honda Shadow Spirit 750 next Spring. I looked for threads on batteries and battery recommendations but didn't find anything. I am looking for a great quality battery and I'm willing to pay for a quality battery as opposed to just getting by. Any recommendations???

Thanks!

Yuasa AGM Japan/USA made would be my choice. They are OEM and I never had one go bad yet after 60,000 mi. on the road and all have been original factory battery. Now I would say cranking 6 cyl. vs a vtwin is by far less stress on the battery especially after long period of not riding and this from own experience. Proper storage also contributes to longevity of the battery. The new lithiums are getting great reviews also but do require a different kind care compared to a normal wet cell battery. Be sure to follow manufactures instructions.

I can't believe you'll do better with lead-acid technology than a Yuasa-brand AGM. I got 8 years out of my last (and only) one with very minimal maintenance -- basically just connecting it to a float charger when I knew the bike would be parked for more than a couple of weeks.

Currently I am using a Shorai lithium-ion battery but it will be at least a couple of years before I'll know if it is good enough to recommend. So far there are a lot of pluses and very few minuses but given the price it needs to demonstrate longevity.

Correct me if I'm wrong (horrors!!) but don't you need a special charger for lithium-ion batteries?

You *could* look at it that way.

In fact, though, you need a charger that is NOT special -- i.e. one that does NOT have a desulfation mode, which is highly desirable on a charger for lead-acid batteries. That mode depletes a l-i rather than charging it. You also don't want a high-amperage charger for a motorcycle battery; the issue is the same as with lead acid: internal heat buildup can damage the battery.

What I found extremely effective was a 700ma trickle charger that I bought from Harbor Freight for $7. As "smart" as it gets is a red light that comes on when the unit is plugged into an outlet.

Wow! I think I am agreeing with most of the post but especially about the trickle charger or a maintainer, but I really agree with the original post, the battery is getting old replace it before end of life and it fails. Younger days I would run a battery until failure and then spend a lot of time jumping off vehicles or getting stuck in places I shouldn't be, yep learned a lot over the years.

Shorai lithium-ion battery:

As soon as one quits working we'll know how long they last. Sport bikers have been using them for years and haven't blown themselves up yet so we know there safe. The two major advantage of a lithium battery is they 1/4 the weight of a lead battery plus we don't have the starting problems from a weak battery we are plagued with because they keep their charge for a very long time. My two sons are also running lithium (HD & Suzuki) so I did buy the charger for the Shorai battery.

One thing against lithium is the up front cost. But if you're running new batteries very two or three years like a lot us are doing then cost will level out.

P.S. If you do go Lithium be sure and read the info on them, they are a different animal to deal with.
