I need support to use 3rd party battery on G1.

Thanks for helping!

I don't think you can go back in firmware.
If your 3rd party battery is encoded, it should work.
If not, it probably won't.
Encoded batteries are cheap on the bay. I have a few and they do work.

Danke!!

How do you find they compare to OEM batteries in terms of holding a charge? That's always been my experience with knock-offs; rated at or better than the OEM, but real world performance is far from OEM. Thankfully I've never had the worse experience of cooking electronics by using a knock-off battery (though my knock-off MacBook Pro battery has many a quirk of its own, like only being able to charge if low when the battery is cool, so I can't really charge it while I'm using the laptop extensively...)

Thanks you for supporting. I've bought 2, the result is:

I actually prefer the after market to the OEM.
Even for my Pens, they last longer.
That's my story and I'm sticken' with it...

Does anyone have a specific battery from a specific seller on eBay or elsewhere that works with the G1 and the 1.5 update? I have not found one that I have contacted that will confirm they work.

There is another solution.

You can load the G13 hack, which is also available for the G1 (I have done this myself).

You can load it, and set the firmware version to 0.0 !!!!!! Along with that, you can also set it to use 3rd party batteries.

Then if you don't wish to have the hack, you can then update to the Panasonic firmware ver 1.4

It's not an illusion. The aftermarket batteries are 1300 mAh (milli Ampere-hours -> it's a measure for how long the battery is supposed to be providing charge), whereas the OEM batteries are only 1250 mAh, which means the aftermarket ones would last a bit longer. I'm about to order one as well since my adventures using on-camera flash are making me run out of battery fast.
