My original starter was pretty lively but gradually got slower until it gave up the ghost. It behaved just like a flat battery. The reconditioned replacement is not as rapid as the original ever was but the engine starts just as easily.
The JMT lithium has just 4 amp hours but is more than up to the task. Lead acid will only deliver 30% of its charge with any oomph so 4AH lithium is the same as 14AH lead acid.
Lithiums appear slow in cold weather. The trick is to turn the engine for a few seconds. Then switch off and try again, waiting for the preset routine. It will then spin and start the engine as many times as you like. You will overheat the starter before you flatten the battery.
The slow engine turning warms the battery and circulates the oil so it’s all good.
The Odyssey at £110 shows a very high burst current but it’s academic value - the starter will never pull that much. The full 14AH capacity is only available over 20 hours so for 14AH = 0.7 Amp. Not much use for anything. The quoted reserve capacity is just 20 minutes. Basically if the alternator stops, that’s all you have before the bike stops.
Based on that, I thought the £65 JMT lithium was at least as useful for 1/2 the cost and 1/5 of the weight. It’s big bonus for me is no damage if left unused for months. My garage does not have mains power.
