Battery Holder Assembly

Before it damages your valuable MPU, remove that leaky NiCad now and use this improved off-board battery holder and your 3 AA rechargeable or non rechargeable batteries.

This battery holder assembly has a 12" easily removable snap connector and hook & loop strips so you can mount it just about anywhere in the head of your machine. Several improvements have been made to this new battery holder assembly. For instance, the holder itself is a nice flat pack which will mount much easier. The 1N4004 diode was replaced with a 1N5817 diode, which has a much smaller voltage drop. The diode is mounted in the battery pack itself, so it's very neat.

 
Holder #1 has a diode installed so you can use it for regular Non-Chargeable AA-sized batteries. Holder #2 has a straight wire installed so you can use either NiCad or Ni-MH rechargeable batteries. The actual holder is for 4-cells but I used the first battery position to install the diode or wire. All you have to do is solder the red wire where the old battery's positive terminal went, and the black wire where the old battery's negative terminal went. The connector is polarized so once the wires are soldered in the proper place, there's no chance of connecting it wrong. Please be sure to order the proper style depending on the type of batteries you plan on using.

Backup Battery Capacitor

This really is the best solution in my opinion, using a small capacitor instead of a battery. Tests have shown this will keep your settings for over 45 days, and there's NEVER a chance of battery leakage, since this is not a battery! I secure with a dab of silicone.
