I see lots of talk about jumping from another car to start a discharged 12 volt battery. Looks like the use of a 1 or 2 amp charger with intelligence would work as well. I see this battery is a very slow charge and discharge type AGM (absorbed glass mat) battery.
Don't beleive everything you read or hear, I was overseas for close to two months and battery was fine.
