A+ For Lectrosonics Mics
I tried these recently in Lectrosonics wireless mics and got excellent run time compared to Duracell & Procell batteries. Amazed that the mics worked great down to 5.2 volts.

Lasted longer than Procells
Rayovac batteries seem to last longer than least that's what I've found using their 9volt batteries in Lectrosonics LM Transmitters. Definitely surprised by that!

Do I need capped batteries?
Capped batteries are for applications where the 9 volt battery will be traveling extensively. The cap is a replaceable, detachable terminal protector that safeguards + and - leads from shorting out during travel against conducting metal objects such as wires, other batteries, loose change in your pocket (ouch!), etc. Most applications do not need them but they are convenient for identifying batteries that have been used.
