How to tell when it is time to replace your battery

Apparently waiting nine years to change out the second Yuasa in my '06 GoldWing was not the right way.

Don't compare a battery dying in a Goldwing (at least pre-2018) with one dying in a Spyder. As the battery loses its oomph in a Goldwing you get plenty of warning with slow cranking, dimming headlights, etc. In the Spyder you don't get such a good warning as it is voltage sensitive. As soon as the voltage drops to below 10.5 when you hit the starter, you're done for. And that can happen without the usual signs of the battery dying, like slow cranking. And since the headlights don't turn on until the engine starts you don't have them for a warning factor. I got five years, or was it six, out of my Yuasa in my 2005 Goldwing. I got 5 years out of the one in my current Spyder, but I sure kept a close eye on it during the last year.

So far has worked pretty well for me and my herd.

Batteries are the one item you rely on the most on your vehicles but yet they are the most unpredictable items. I don't remember any cars or motorcycles I have had for more than two years and not having to replace the battery. Yes, the AGM batteries seems to last longer than the old style flooded ones, but they still die a certain dead sometimes. If a battery is more than 4 years old then I would replace it just to be safe (I did on my RT-L) because you know it will give you problem at the most inconvenient time. I agree with few posts here that nowadays you should have a portable battery jumper with your Spyder, I have one and don't have to use it just yet (knock on wood.)
Cheers!

Well yesterday I went to the "Battery Warehouse" I regularly deal with to purchase a Deka ETX18L AGM battery...Owner says NONE available...Called his supplier and said they don't know when...Now we have a powersport battery shortage???

I like Deka's battery cable attaching system better than any of the others...Plus they never corrode...

I have one coming from another source but it will take a couple of days...And they only had one...
