hi i have 2 batterys one is 12v 12ah/ 20HR. THE OTHER IS 12V 12AH /2hr. witch is the best lasting batt please ? regards crimsonsnake0
I was always under the impression that all batteries were rated using the 20 hour discharge rating. So how is it that you have a battery rated at 2 hours? This is a new one on me......

hi have rechecked and it definatly says 12v 12ah/2hr anyone know if this is better or worse than 20hr rate ? CHEERS
Well the first one is .05 C the second one is .5C. I'm assuming these are SLA batteries? For ebike use the 12ah 2hr (or .5C) battery is much better.
