Basic rule of thumb on using LR with Ego type batts.
They will work, but you will get less battery life out of them (drain faster) and you could damage your battery to where it dies. There is a little circuit inside all of our factory batteries that help to keep them healthy, but the LR gear can, and has for some people, burned out this circuit rendering the battery useless.
Unless you are able to disassemble the battery and replace this little circuit board you will not be able to use the battery anymore.
Look up member Drodz and see his posts in the various threads about this subject to more in depth info. I had it happen to a battery and am now very cautious about using LR.
