We all know lithium batteries are the best for trail camera performance. I am about done with alkaline after having a couple leak and ruin cameras. Not only do lithium batteries last longer, but depending on the camera model, you will get faster pictures and better flash. I have started switching all my trail camera batteries over to lithiums. The best price I have found on 8-packs of AA Energizer Ultimate Lithium batteries is at Amazon. Prices can change at any time so click the link to see the current price. For reference, the lowest historical price I have seen anywhere is $10.74. Sometimes you can save an additional 5-15% by using the subscribe and save program. I subscribed to get some every 3 months. The current price is listed below.
I recommend you don’t buy these from the “Other sellers” on Amazon or in bulk packs elsewhere as they are often counterfeit. The batteries above will be in retail packaging.
