Yes, I've bought it ( 1930mAh) and works well.

Is there any 3rd party battery user that can record 2 hours non-stop with it? Is there a particular brand or seller with batteries capable of doing that, even without charge level indication? I mean standard size in-camera batteries, not external solutions.

I have a bunch of cheap ebay batteries, i just swap and recharge every half hour or so, they are so cheap it doesn't matter if i shorten the life cycle of them.. 2 for $14.. as long as they work for 50 charges .. ive not had a issue with any of mine yet. Heck its 2 for $17 with a charger.. really compared to alkaline batteries they are a bargain.

just cheap ebay deals.. like these http://www.ebay.com/itm/2x-New-Battery-for-Panasonic-DMW-BLC12-dmc-gh2-Blc12-Digital-Camera-/221015474850?pt=Batteries_Chargers&hash=item33758c82a2 mine i got with a charger and have held up well.. no battery indicator as expected on Pani cameras but just keep swapping them and charging them.

@manuelrm about the 1930 mAh Ecell battery: on ebay they state it is 7.2V, so I expect it to have a proper decoder to prevent the camera from shutting down within two seconds. Could you let me know if it shows battery status and does a gentle shutdown when the battery is empty?

edit: i found this comment by oneday stating that these batteries discharge within two days when you don't use them. Is that also your experience?

I've tested this battery a bit more.

At first I thought it would be > 8.4 V. But when I started measuring it it looks like it really is a 7.2 V battery:

• real battery: full = 8,35 V / Empty = 6,5 V / battery status indicator = yes
• fake battery: full = 8,35 V / Empty = 0 V / battery status indicator = no

So it seems like there is a third camera mode between original battery (decoder) and DC power (> 8,4 V): under 8,4 V but no status indicator. Any thoughts?

Recently, my main GH2 developed an issue where it says "this battery cannot be used" when I use a first party battery but works when I plug it into the wall.

While I plan to send it back, does anybody know whether it might work with a third party battery or one of the other aftermarket power alternatives?

I've used Wasabi batteries for years in all my cameras. They do not indicate battery status but have always proven safe and reliable and I charge them in the OEM chargers. They charge fine in the Panny chargers and Canon.

@thepalalias: Ah, then it sure sounds like a defect in the body.

I have one of the Ecell batteries and although it is rated at over 1900mAH it only lasts for about half an hour - useful for getting you out of a hole but not reliable to use as a main battery. May try one of the lower capacity batts as they might be more accurately rated. Again this is just a "get-out-of-jail" batt as I wouldn't want to trust them as a main power source.

I'm doing a test now, but basically there are no guaranties. Should have some numbers soon.

One thing i do know about 3rd party batteries is that your camera will have a slight burning smell when the battery voltage drops low some time before the camera shuts down. I guess as voltage drops current increases and some of the components heat up. My GH2 hasn't been damaged by this but it can't be doing it any good long term.

Solution is the use the fully charged batteries for only a short period (half hour max then swap)
