Cheapo Ebay triggers and Batteries

I bought some of the cheap pt04 ebay triggers a while ago and they worked fine at first (with the supplied alkalines). however I then got some rechargable AAAs and am now having problems triggering with them, they only work at a very close range.

The rechargables are rated at 1.2v and standard AAAs are 1.5v, do you think it is this that makes a difference?

Anyone else had similar issues?

No, because I don't try rechargeables in everything. Give it a shot with alkaline AAs (or AAAs) and see if that corrects things.

Re: Cheapo Ebay triggers and Batteries

It has been a recurring topic.

Fresh batteries OF THE REQUIRED RATINGs for the electronics are a good thing, and not a significant cost for the PT04's.

I (try to) always make sure the receivers are switched "OFF" when not in use.

I also try to keep the Xmtrs and Rcvrs in a hard case, along with spare batts in my bag.

Some triggers "test" buttons are easily accidently depressed, running down the battery when you aren't looking. A friend's AB triggers went flat in the bag, only to be discovered at the start of an event. The assistant ran to the closest store for replacement batts (and a spare set).

Also - if the PT04's operate in the 433MHz frequency range...this frequency is also used for many other consumer devices (garage door openers, older wireless phones, etc.). I found an antenna mod for the Xmtr better matched the antenna to the frequency, and solved the inconsistancy issues I had with Cactus V2s units.

I found fresh batteries always had mine working better. Now they just sit in the drawer at home.

Just one of the reasons why I switched to the Cybersyncs.

The trade-off's result in consistent, reliable firing of the flash.

Gary,

all chinese "cheap" radio must use alkaline battery. If you use NiH rechargeable battery may experience degradation on syncronization of radios. I use them and with fresh recharged battery of 850 may work for a while.

Sorry for my ugly english...

Hi Gary,

Yes, I would say that the transmitter would probably show a significant power output drop in a reduction of 1.5V to 1.2V per battery. You will probably see the same reduction in power output (and range) when the alkalines drop below 1.5V too.

Regards,
