This morning I e-mailed the head office of Wildlife Whisperer, and was surprised to get a quick response from someone called Jason.
' Hi Keith,
It then went on about various types of batteries, (it takes 12 AA type), and that they have found a huge variation in quality and performance of various brands.
' We (and Bushnell) recommend the Energizer Lithium range of batteries as we have found that they consistently outperform other brands including Duracell and should offer longer operation when used in your trail cam.'
There was other stuff about them contacting Bushnell's UK distributor, to see if they have anything else to add.
Now, so far so good; perhaps.
At least I got a response.
Now when I came up here, I did bring some spare batteries, (Duracell), just in case the ones I had ran out. Despite the ones in the camera still having some power left, it would seem it's not enough to trigger the video at night.
I can't help thinking that some sort of 'warning' about batteries, and their recommended ones, should come with the camera somewhere.
They do say on the packaging that the battery life is up to a year.
Probably is if you only use the camera a couple of times.
The set of Duracell have been installed, so a test will be made this evening, to see if anything appears around the hen house during the night.
At the moment the weather is so bad, that I can't get out to any shops to get the Energizer batteries that they recommend; hopefully that will be tomorrow, assuming things work this evening.
