Adding the lithium cartridges to my Reveal cameras allows me to run a camera all season with the Solar Panel. Great when the weather is overcast and the panel can't maintain a charge. The cartridges carry the load until the sun comes back out.
Wish I’d had purchased them long ago. Also purchased solar panels. If you can afford to buy this set up you are way money ahead because the cost of AA batteries …. .
Well I recently bought 4 and one of them didn’t stay charged in one of the cameras. But I went back to Florida and can’t switch it out. So I lost a month and 1/2 of pictures. I have a work order it to reopen when I get back up there in October.
