Battery amp 21 vs 20?

[RobNAz]

I need to replace the battery in my 84 standard and I'm looking at a gel battery. The gel batteries I'm finding are 21amp, rather than the 20amp original that all the lead acid AGMs have. Of course that's when I can find the amp rating - many cycle stores don't bother to list the battery specs... I've looked through the forum and can't find a clear answer - is there any problem with using the 21amp battery on an older wing? Thanks in advance

It should not be a problem at all. Amp hour is the rating used to tell consumers how much amperage a battery can provide for exactly one hour.

not an issue.
Just curious, why a gel over AGM?

AGM is a better battery for a motorcycle by most standards (lighter, easier to charge, better for fast, high amp discharge (ie starting the bike), wider operating temp).

Gel batteries tend to be best for deep cycle/secondary batteries, not a starting battery.

Thanks for the info.
As for choosing gel, I live in a hot area and I can get a gel battery with longer warranty for less than AGM, and my trickle charger is gel compatible. Is there a reason I should go with the AGM battery instead?
