Hi Folks
Can someone advise me how often I should replace my battery?............regardless of what I "think" about it's condition, is there a "smart" replacement schedule for one. BTW, I am into my third summer coming up now and the battery has been inside through winter months on a regular monthly slow charge and topped up regularly with distilled water.
Thanks

Sounds like your doing everything right battery wise, but those stock lead acid types only last 3 to 5 years, max. in my experence.

There are some folks that have gotten more life from them, but not much more.

There really isn't a hard and fast rule on battery life or replacement schedule. You may get 5 years out of this one, and only 2 on the next.

I switched to a sealed maintance free AGM, (absorbed glass matt) type, have been told that and a battery tender to keep the charge topped off and I should never have to replace it.

So far so good, 3rd year and it's just like a new one, but we all know how that goes.

I've replaced the battery in my Nighthawk once, and a few of my friends end up replacing theirs every few years. We've never been stranded by a dead battery (as long as the engine is maintained and started well) and when the bike starts to crank slowly, or the lights seem a little dimmer than usual (instrument lights) then it's about time to replace it. 5 years is the most we've ever gotten out of a standard battery. Some auto shops can load test it for you, but you have to take it out of the bike to do that.

Take it to the local battery shop and have it load tested. If bad, replace it. If not bad, ride with it. They will flunk a load test about six months before they go belly up and leave you.

My original battery lasted 7 years and could've gone longer. I replaced it before we headed down to Colorado just to be safe. I figure they're cheap enough to replace every 5 years or so. Your best bet is to keep it on a float charger when not riding and you'll keep it fresh for a long time.

I still have the original Yuasa in my 01. Like some other folks, I did replace it at about the 4 year point, thinking it'd be good preventative maintenance. I replaced it with a Koyo from some online vendor. 8 months later the "new" Koyo went bad, so I put the original Yuasa back in, and it's still going strong. When it does need replacing, it will be with another Yuasa. Cheap batteries aren't worth it. (YMMV)
