I have a Snapshot Sniper LCD board that is in a build with a p41 and works well. I really like the features and adjustability of the board. The problem I am having is very poor battery life out of the 9v board power supply. After putting a fresh 9v battery in and taking about 200 pics...the 9v battery is down to about 6.5 v.(this happened to every battery I used so far). Is there something draining this battery or is this just a trait of the LCD board?

Don't have definite answers but question or maybe something to check.
What is the lowest voltage the sslcd board works at? I know I've used 9v on the aio down to 3.something volts...too cheap to buy batteries all the time.
Second is what the settings are, refresh time, etc. Maybe change those so the camera isn't refreshing so often??

Something is going on there Joe, I have always gotten several months service with the LCD board and 9 volt batteries.

Yes, something isn't right.  The battery should last 6 months to a year.  Does the board have any corrosion or has it been wet?

I kind of figured something was wrong....no visible corrosion and I got the board used so I'm not sure if it was ever wet.....anything else I should look for?

What are the settings, refresh, etc.? Is it set for the right type camera (assuming it would have to be)?

Jon....I have the refresh set to 2hrs....the shutter at 1.5 sec...cam type 1....day delay 5sec....night delay..10sec.....the set-up works great,it's just tearing up the 9v batteries. I had the walk-test turned on,and I turned it off but haven't tried it yet with it off.

The walk test wouldn't cause the issue.  How are your soldering skills?  I can send you a new voltage regulator and see if that fixes it.  Send me your address and I'll send one.  Here is where it is, where it shows 5 Volts.

Thanks Gary......I did check the voltage at the regulator with the board turned on and had exactly 5v.....does that mean its okay?

Not always.  I have had some that the voltage was good but they were drawing way to much current.  Measure the current draw of the board before and after changing the regulator.  When you measure it, turn the motion switch off and measure it for about a minute so that it has exited walk test.  The board should go to sleep and the current will drop at that point.  It should be 60uA or so.

Gary...got the regulators..Thanks. I decided to check the current at the voltage regulator and did have about 60uA after a minute or so....but happen to notice that the 9v battery was unusually warm.   Any ideas?  Maybe a bad battery holder?

There's a pretty serious short if the battery is getting warm.  Look it over real good for some stray solder that could have been dropped on the board when soldering the wires on, or a strand of wire touching something it shouldn't.

I switched out the voltage regulator and have the cam out in the woods for testing. After previous testing in the basement...the battery never got warm again...I checked for stray solder and couldn't find any shorts....I'm wondering if the battery got warm when I was testing current at the voltage regulator?

Testing the current wouldn't cause that, but hopefully it was the regulator.  Were you able to measure it after replacing the regulator?

I checked the voltage (5v) but not the current!

The voltage regulator did the trick...the battery voltage has been stable since replacing it. Thanks again Gary!
