What is the longest life you have gotten out of a battery?

 

I had to replace the original after 4 years. The replacement lasted 4 years and now going on 4 years on the 3rd one. It is still going strong so maybe I will get more than 4 years out of the last one. I have never used a tender on any battery because I ride year around and the longest it will sit un-attended is 4-5 days.

 

I had 12 years out of one once but they usually last 1-3 years.

 

Just replaced the two original batteries in my '01 Dodge Ram.
I know,this is for bikes.

Still had the original bat in my '06 Road Glide before I sold it,it was 4 1/2 yrs. old

 

Seven years from the original in my Fatboy. Stored in an unheated garage and hooked up to a battery tender. It was still working well when I replaced it but, I did change it as I didn't want to get stranded somewhere.

 

Just had to replace my battery in my 06 Ultra. Got it in Feb of 06.

 

Just changed out the battery on my 06 SG. Picked the bike up in Dec of 05. Still held a good charge but didn't want to take an chances since I work nights and it's a long walk home.

 

There is no Normal when it comes to battery life.
Does your bike spend half the year (winter) parked and on a tender? The rest of the year do you ride a couple of times a month on the weekends? That may get you 10+ years form the battery.

Live in a hot climate? Ride pretty much every day with multiple engine restarts running around town? Don't be surprised if you need to replace the battery in 18 months or even less.

 

9 years on a Interstate megatron battery and it was still going good but figured 9 years I got my money worth out of it. And oh ya put another Interstate megatron. Bike 2011 RKC 1year 4 months still going strong. Hooked it up to a tender for winter but spring is early so it riding time. If Interstate makes a battery for my RKC that's whats going into my bike.

 

07 Ultra 6 YRS. no tender, EVER. I was amazed....This bike for some reason needs a tender bump once a month or so.
