Re: battery

First, the battery is a Lenmar PBA50 found on ebay.
Second, place the amplifer onyour lap with the battery cover off and tap it on your leg, the battery should slide out the back.
Third. I have 2 of these amplifiers and both would not charge or play on battery. The problem is the metal spring contacts the make contact on the battery, they get out of shape and fail. I bent them around until I was able to make the work, but do not like that solution. Beside the left in of the battery is a small "pocket" if you will. I opened up the amplifier (BECAREFUL the handle come loose and there are nylon washers on each side total of 4 that will do what ever they can to escape.) With the amp opened I located the 2 wires going to the metal battery contacts and cut them off and removed the contacts. I then drilled a hole into the small "pocket" and routed the wires down thru the hole. I remove the battery and carefully soldered a wire on each battery contact. I then put a et of connectors on the wire end making sure I kept the polarities correct and plugged the into each other. I now have very good battry connection and all works well.

Gel cell batteries usually are good for 3 to 5 years and from your description, it sounds like the battery is not recharging properly. They will indicate a full charge but in reality, do not have the stored power to operate the device. Check for replacement batteries at your local burgular alarm shop or buy online BUT make sure to match the voltage and AH (amp hours) ratings.

Microphone drains batteries even when off.

If you are using Nickel-Metal Hydride, rechargeable batteries, they are not designed to hold a charge for a week---just a couple of days if that. They are meant to be continuously charged or when charged, used immediately; best use for cameras/flash.

The microphone is no power

This mic does require a longer power button "press" cycle...used during on and off in hopes you don't turn mic off or on accidentally. Check the battery, battery polarity and battery luck, then it's probably been dropped one time too many.

I am having a similar problem to what others have. Regarding the battery. I cannot seem to get the battery in tight enough and the mic keeps cutting out. I have taped it, even put some wadded up paper...

If the battery snap on connector no longer holds the battery, then that snap on connector needs to be replaced. You can order the part from Shure or send the mic to Shure to get repaired.

I have a Liberty MPB 4500, and every time i increase the sound it get disconnected Why?

I would suspect that the internal battery may need replacing as it cannot produce enough output to sustain the system at high power.
There is a lot of support available on this website (including video of how to replace the battery)
download the manual here

I have a Beta 87A wireless that will not power on... i have obviously replaced the batteries any thoughts

Your power switch may be damaged.
If the power button was pressed too forcefully, the switch on the circuit board in the handle of the 87A may have sustained damage. If the button no longer "clicks" when you depress it, that may well be the problem.

Battery charging

you need to replace the battery, don't leave your laptop plugged in when not in use, it will reduce the batteries life and eventually it will fail.

hope this helps
