Need a replacment battery for the MX 3000 dynamic entertainment

Get rid of it, and buy a new one. It will be the best.

If you haven't replaced it yet then it's normal - the rechargeable battery has aged and must be replaced. Here is one

Amazon.com sells them. MX-3000 replacement battery @ Amazon Should be a pretty simple replacement, possibly a few screws on the back, use care when removing the old battery, as sometimes these connectors can cause damage from bending the pcboard it is attached to, same with installing the new battery. Don't be afraid of it, just treat it like a lady and it'll make you breakfast. Well, probably not. Good luck!
Thanks for using FixYa!

My company carries a replacement battery for the MX3000.  The p/n for our replacement is PC036067-(V1 or V3 suffix)  You can reach me via email at [email protected] and I will be happy to help you.
There are three important considerations concerning this battery.
1) Please note that the original version, supplied by Universal Remote p/n PC046067-H for the MX-3000, was discontinued by the battery manufacturer.  The PC046067-H had a typical capacity of 1800 mah.  My company has worked with the manufacturer to provide a replacement that has a typical capacity of 1400 mah but is identical in size to the original although slightly thinner.
2) Universal Remote used two different connectors on the PC046067-H with no deviation of p/n.  We carry our replacement with both connectors (our p/ns use suffix V1 and V3 to differentiate).  V1 is a simple white plug and V3 is different in that it has pressure tab built in.

I had several batteries that I ordered and they have been all purchased. Since I make no money on the batteries and can only order in bulk I will only order them if I can round up over 50 customers who need MX-3000 batteries. If you need one, please go to www.totalcontrolremotes.com and get in touch with us by putting "MX-3000 battery needed" and we will add you to the list. Either way wil let you know by mid-March 09 if and when the order will be placed for additional batteries.
