Sorry to hear about your loss, I can just imagine what that feels like /ubbthreads/images/graemlins/ooo.gif
The original Classic 9N (probably my favorite of all my SureFire collection) used the C800 charger which allowed the whole light to slot in and be recharged without having to take the battery out. It also had the capability of recharging the bare B92/B90 battery on its own thanks to a little spring loaded bit that pops up inside when the whole light isn`t there. I believe later Classic 9Ns only came with the cheaper C600 charger which offered the charge-in-light option only, or at least mine does. The modern day 9ANs do not have the charge-in-light capability any more, so if you only have a C600 charger, you`d need to get a new one (CN400, does the cell only) to charge a 9AN battery, or buy the whole light-batteries-charger-powersupply package which could work out slightly cheaper than buying them by themselves.
If you have the original C800 unit, it`ll charge the B90 battery that comes with the 9AN just fine. But although I don`t yet have the 9AN, I hear it isn`t as good as the original. The lack of charge-in-light capability is a major factor for me. And the KT3 is nowhere near as good as the T3 Turbohead for long throwing light. Luckilly for you, 9Ns aren`t *that* hard to find. They turn up on Ebay quite often, and I recall recently seeing a guy in this forum possibly thinking about selling his never-used one - that would be worth a look.
