I have a JR 3810 ADT Radio Set. I currently remove the battery to fast
charge. If I make up a lead to fit the transmitter, can I fast charge
through this without removing the battery? How much current can you push
through the transmitter?

Many thanks
Steve

You aren't pushing anything thro' the transmitter as the cells are wired
straight to the dc jack. At best / worst they#ll go thro a fuse.

You can fast charge quite happily at up to 2 to 2.5 amps if the fuse will
take it. I charge my trannies at c1.5amps all the time with a cycle every
now and then. I had to change the fuse in the MPX tx though.

Thanks for that. It will be much easier than constantly removing the
battery. I only want to charge at 1.2A so that should not be a problem.

Thanks again
Steve

Is it not the case that some trannies have a diode in series with the
external charger socket? As many fast chargers apply a pulse of discharge to
test what is going on during the charge process they may not work correctly.

There again I may be wrong!!
