I know that Blink recommends Energizer - and the cameras even come with them. I’m assuming there’s a contract with Energizer, so maybe Blink can’t even comment on other brands… have other users tried other brands of lithium AAs? AmazonBasics carries a line of them. I’m not sure if there’s really any cost savings to them.
I’m about to make a purchase of A LOT of batteries. We have a total of 8 Blink XTs now - at our house and at my in-laws. Life would be so much better if we had could use rechargeable batteries or if there was a battery pack of some sort. Oh well.
