R123\'s??

Hi
this is my first post on the forum. i've tried looking through the threads for info on R123's but still have some unanswered questions. Can anyone help.
Firstly - I've read about protected Li ion cells - what exactly does this mean?
Secondly - it seems that the Inova XO and T1 can't take R123's. Can anyone tell me why?
Thirdly - does anyone know if the Gladius works with them??
Thanks
Aidan

Re: R123\'s??

There are three things that you should not do to a Li-ion: overcharge above 4.25v or so, let the voltage go under 2.5v or get the current over certain limits. If you do, nasty things happen, from battery destruction or degradation to fire and blasts.

Protected R123 have cut-off mechanisms to avoid tresspasing some or all those thresholds.

An R123 just charged can have 4.2v versus 3.2v on a new CR123. Some devices designed for 3.2v can't take 4.2v, while others have wider margins of operation.

I don't know if the Inova and Gladius can take it or not.

Some rechargeables don't physically fit into the light's body (they're too fat). Sometimes rechargeables are a tad shorter than primary cells and you need a little spacer to make proper contact.
