Yeah, I have already sent them an email. Shorai gave me their details.

If buying to have "in stock" for when your battery fails:

Lead/Acid not filled = forever
AGM never used depends on storage conditions - in a climate-controlled garage the worst I've had was a year and I had one for about three years that was fine when I installed it.
Shorai LFX18A1-BS12 (the only I use) again, I suspect, depends on storage conditions but I've never had one not work after sitting on a climate-controlled shelf unused. I buy 2-3 when I find a good deal and no telling when I will use them.

I'm finally ready to buy a spare. My existing one is going well but is over six years old and I don't want to wait on lead-times when it dies.
The replacement will be LFM21L7-BS12
They seem to have dropped the "X" in bigger sizes - the more modern "M" apparently has over-discharge protection
They have also discontinued the 6 size for the 21Ah - the 7 has the same footprint, is slightly shorter in height, but has the same 315cca

My question of you is, do you charge the ones you have on the shelf and, if so, how often?
Cheers
