After almost ruining my eyes trying to read the reports I noticed that all of these batteries ended up being rated at 3.7 Amp/Hr.
With the Royal Enfield UCE's 14 Amp/Hr battery rating requirement I wonder if these batteries would be suitable and would match the charging system?
I noticed they were conducting a 100 amp discharge test so I'm assuming the tests involved actually starting some real motorcycles?
I mean, they could have subjected the batteries to a 1 second or so Zap and said, "OK, there's another one!".
On the other hand for an Iron Barrel, AVL or UCE that is kick started I'm sure their batteries would have enough power to activate the ignition and headlight but at $160 + I'm not sure they are worth it.
