I don't have any problem using aftermarket batteries. xpatUSA mentioned the Li-ion batteries not being cheap, so it's a question of how much you value the cost of replacing them (easy to do when the camera is current, annoyingly hard a few years after Panasonic discontinues all the models that use a certain battery) versus after many yearsĪmazon lists lots of aftermarket batteries for the first MFT cameras, the G1 and GF1. If it's nearly dead and you let it sit for six months, it's likely toast. If the battery has a decent charge on it and you let it sit for a month or two, you're probably fine. xpatUSA mentioned the Li-ion batteries not being cheap, so it's a question of how much you value the cost of replacing them (easy to do when the camera is current, annoyingly hard a few years after Panasonic discontinues all the models that use a certain battery) versus after many years just needing to set the clock every time you first put a battery in the camera when it hasn't been used for a while.

I think it would be better to leave the battery in and check its charge every six months or so. So I'm not sure I'd follow this manual instruction in any event. And I'd rather have that easily replaced battery go irretrievably dead than have the built-in clock battery die. I probably use all of my MFT cameras, including the older ones, more often than once a year.

Still, I think there is a big difference between 'not using the camera for a long period of time,' which the manual seems to think may mean more than a year, and your advice to 'never leave a battery inside a camera when you're not using it.' I'm definitely not taking my batteries out every time I put my cameras on a shelf. I always keep the battery in my cameras when not using them, and I've never had any ill effects from this. Storing a camera for a long time without a battery in it can kill the built-in battery that keeps the clock/date working, probably requiring partial disassembly of the camera to replace. I just checked my G9's manual and did not find any such statement.
