Hi, I'm on the waiting list for a Wisper Wayfarer. I've chosen the smaller of the 2 batteries as it is a 60th birthday present from my wife and kept the cost down, I'll buy a spare battery myself. Is it better to buy a spare battery now and store it? (I'm guessing unused batteries don't store well?) Would batteries be stocked for a few years even when the models change? Thanks.

if your not going to use it then no point just letting it sit while the warranty runs out these things dont like not being used.

Thanks, yes, that's what I thought. I would presume batteries would still be available for a particular model 2 or 3 years down the line.

All the best, David

I have two batteries, I just alternate them, so both get used.

If one of the batteries fails, and that does seem to happen, I dont need to worry short term about fixing a battery to keep my bike going.

That is the right way to do it and will promote the longest battery life (of them both together) as well.
And only charge when at the controllers at the point of cutting off power to the motor, or just before - assuming some SOC indication is available. Remember, batteries have a set number of "good" charges, before decline sets in, but the number is only (possibly!) really known (if you kept count), the day the decline sets in!!
I take the 2nd battery with me when I can guess that the first one may run out of power before I am back home, or for long journeys, then I simply charge both beforehand and take them both, even if one is not fully discharged.
But this is really only practical, if the OP has a bike that allows Batteries to be easily and quickly swapped - some bikes simply don't make that easy......and then I wonder just how often the batteries will get swapped, and as someone else already correctly pointed out, that is simply not good for a battery to be not in regular usage. They are way too expensive to leave lying around.....
I hope this helps the OP.
regards
Andy

Hi Andy
Thanks for that. Yes I imagined alternating like that, but for now I think I'll wait to get a second battery and see how my usage goes. Cheers.
