That last battery says "No Charging". Am I understanding this?
Lithium have a different charge profile from SLA, Nicad, and NiMH. From what I understand they don't do bulk charging?

Couple of our guys came to check some thing at the shop today, the OSP crew ready room was full of smoke.Our horizontal directional drills use sondes in the drill head for tracking purposes. We recharge the batts every time they come back to the shop.The batts we use are smaller than normal sonde bats so they fit into an adapter, sabot type of thing.The industry standard is double C cells, but the vibrations are such that normal C cells will give you intermittant service. So most use a special 3 volt battery that is probably just 2 c cells welded with heat shrink.Our new locators and sondes use a voltage a bit higher than most 3.3 volt lithium. They like 3.6 volts I believe. So the smaller batteries are adapted to fit the sonde, but the charger for them requires the adapter.They really should make the charger such that the larger batts cannot be put in it.Just glad we didn’t have a fire. It did blow the corner of a piece of shelving.
