Re: Battery Life when Unused
I think the main advantage of AGM is that if the bike goes down there is less likelihood of a corrosive leak than with a standard lead acid battery.

Re: Battery Life when Unused
I bought a brand new AGM Yuasa battery (one of the best) online from Battery Source and including shipping I think was about $50-60, no more than a lead acid battery from anyone else. Most motorcycle batteries nowadays are AGM or VRLA (sealed lead acid battery) and you might even have a hard time finding a straight lead acid nonsealed battery in the correct size for this bike.

Re: Battery Life when Unused
The advantages of AGM batteries are no maintenance, sealed against fumes, hydrogen, leakage, or non-spilling even if they are broken, and can survive most freezes. AGM batteries are "recombinant" – which means the Oxygen and Hydrogen recombine inside the battery. These use gas phase transfer of oxygen to the negative plates to recombine them back into water while charging and preventing the loss of water through electrolysis. The recombining is typically 99+% efficient, so almost no water is lost.
Charging voltages for most AGM batteries are the same as for a standard type battery so there is no need for special charging adjustments or problems with incompatible chargers or charge controls. Since the internal resistance is extremely low, there is almost no heating of the battery even under heavy charge and discharge currents. AGM batteries have a very low self-discharge rate (from 1% to 3% per month) so they can sit in storage for much longer periods without charging. The plates in AGM's are tightly packed and rigidly mounted, and will withstand shock and vibration better than any standard battery. Because of their design integrity, AGM batteries can be recharged up to 5 times faster than a regular wet cell battery. :2tup:

Re: Battery Life when Unused
That sort of covers all the bases doesn't it. :2tup:

Re: Battery Life when Unused
All I can say is that for the size for our bikes, the cost of the two are comparable and the AGM is a better deal and should last longer too.
