I believe that all (or most) multichemistry chargers have different contacts for LiIon or NiMH batteries, to preclude any issues. I know Icom BP264 and BP265 have different contact arrangements, so if you put the wrong chemistry battery in the wrong charger, it does nothing. Kind of makes it user proof!

I have no specific knowledge of that exact model battery, but in general LI-Ion batteries must have their own chargers.? While some
multi-chemistry smart chargers might get you by with some, there are safety issues with Li-Ion that require more comprehensive safety
measures. The better systems have an on-board controller in the battery pack that keeps track of individual cell condition and controls
the charge.? It protects the individual cells from overcharge, and separates a faulty cell from the rest of the pack so it won't burn up
violently.? And yes i once had a brand new Li-ion battery go up in flames all by itself.? Fortunately there was a empty metal trash can
to scoop it into and take it outside before the sprinklers went off.

I guess Jaguar is a radio model.?? If you have Nimh chargers, it would be best to stay with those or you will have people dropping
batteries in the wrong chargers.? Otherwise buy the factory authorized Li-ion batteries and chargers for the entire fleet and
get completely rid of all of the Nimh batteries and chargers so there won't be any mixups.? This is almost impossible, because
people often hoard and will always keep old ones in drawers and cabinets and they will keep showing up.?

If you are looking for aftermarket batteries to cut cost, stick with Nimh because they are simpler, and you will be less likely to get
burned with a bad batch.?
