oddities, under the skin it is almost exactly the same as any other transmitter pack. So
before spending serious cash replacing it, why not just service it?

The battery cartridge is very simple and consists of only 4 components:

1.

The battery cartridge case top (Part No. 1M10E17801 “UPPER CASE NT-8A”)

2.

The battery cartridge case bottom (Part No. 1M10E17901 “BOTTOM CASE NT-8A”)

3.

The battery (a standard transmitter pack)

4.

The mini-PCB (Part no. T56800 “PCB 9V T982 BATT ASSY”, which is very simple
and has 1 x 400mA Schottky diode, 1 x 0.1” receptacle and 1 x standard charge
socket)

There are two common things that happen with 9Z battery packs that require servicing:

1.

The NiCad battery becomes exhausted and needs to be replaced.

2.

Fast charging above 400mA blows the diode and the battery will not charge through
the main charge socket (there will usually be some melting of the case at its end).
Figure 30 shows a blown diode on the battery’s mini-PCB.

Figure 30 Blown Schottky Diode on Mini PCB

To replace the NiCad battery the operation is simple, although I’d recommend you
replace it with a higher capacity Nimh pack and preferably with your own DIY pack made
from Sanyo Eneloop batteries (the only currently available low self discharge batteries
that live up to their promised performance). Do not bother with Lipos, you get very little
increased performance over Eneloops and you will not be able to do a like for like
replacement. To replace the battery follow the procedure below and refer to Section 4.7
for additional recommendations:

1.

Open up the battery case by unscrewing the retaining screws.

2.

Either purchase a standard battery pack or make one up from Eneloops

3.

Slide out the mini-PCB and old battery pack

4.

Desolder the old battery pack
