RE: It finally happened - GoldOxide_imp - 06-16-2019
I have been fortunate to always get over five years out of a battery, bikes and cages and without interruption of service. The longest was around seven and it didn't really need it until the next deep cold winter. I do not leave the battery on a tendering charge continuously.

Neither do I.
For winter storage, I remove the batteries from all the bikes except the 1100. It's buried down deep and has a pigtail on it so I leave it.
Once a month I pull them out and hook each one up to my Optimate charger for 24 hours and then put them back where it's cool and dry.

When I bought my six-year-old bike a few months ago, the original owner told me that the bike had its original battery, so he couldn't promise how much longer it would last. He kept it on a Harbor Freight tender, which he gave me with the bike.
I was dubious, but still rode on that OEM battery for a few months before a couple of slow cranks gave me enough of a reason to buy a new one. That was a pleasant change from my BMW, which would go through a Yuasa about every three years.
Clock is ticking on my Bonneville. It's battery is on year five...

Bought new April 23rd 2013... never needed anything but a start midwinter to prove things were ok.

Voltage of new battery right out of the box.

Voltage of the old battery after being on a 10A charge for 6 hours and then left to sit overnight.

All done.

Congrats Randy. I assume you mean a 1 amp charger and not a 10 amp charger. Motorcycle batteries are low amperage units. That would be a lot of voltage going into that battery if you used a 10 amp charger.

Voltage is constant, a lot of Amps you meant...for sure not 10A for this battery
RE: It finally happened - the Ferret - 06-19-2019
yes amps, typo. Thanks for catching that PB

The battery will draw the current it needs to charge the cells to their full voltage potential and then drop to a trickle.
Using the 10A charger means a partially discharged battery will draw too much current and "bake" itself. Using a 1A charger will limit the "bake" to a maximum of 1A. Best to use the so called "smart chargers" that regulate and cycle the charging for you so the cells to not prematurely fail.
