PanasonicDMW-BLF19 Lithium-Ion Battery Pack (Black)

I had 3 knockoff brands that I paid like $10-20 each for, but after a few years, the battery life is literally less than 2 minutes of shooting so I just tossed them. However, the original Panasonic battery included with the body still lasts for like 45 minutes of shooting. I needed something reliable a rush and so I got this one, with a full charge, it lasts like an hour of shooting. So yeah, it does seem to be worth dishing out the extra cash. I'll probably get 1-2 more.

I can't testify to its durability yet since I've only had it for a few months, but it has been very much reliable so far. I was a bit concerned when it came packaged somewhat poorly, without even a plastic protective cover which made me a bit suspicious about the scratches I found on the sensors (picture attached), but I decided to keep it and have had no problems with it whatsoever yet.It lasts me half a full day of shooting FHD video (1080p, 23.976 fps) and hasn't caught me off-guard yet in terms of warning about when I'm low on battery.

If you’re going to purchase batteries for your camera always i mean always buy the original manufacturer battery . All tho they cost a little more the performance is better in the long run , especially shooting outside in the winter time 😃

Don't waste your money on aftermarket batteries. These Panasonic batteries are the best for my GH4 and GH5S and last almost 50% longer than other aftermarket batteries.Additionally these batteries hold up extremely well after several dozen charge/recharge cycles where the aftermarket batteries only last half as long as they initially did when new (which was already half as long as the Panasonic batteries!!).I highly recommend these and they are well worth the additional cost.

I love having extra batteries and after trying some of the 3rd party options, I have realized that the original OEM batteries are worth paying for. They last longer than the others by far and also don't give you strange errors that the battery is incompatible. They also seem to hold up a bit bet over time as the others I bought around the same time are already not holding much of a charge compared to these.

...and with these, yes, they cost more than a 3rd party battery, but you don't want to trust those others. The charge time they show is wholly inaccurate when out shooting video, and when the battery dies much sooner than you think, it won't properly write the file header to give you a playable file. Been there, done that. Never again. Buy these, and you're worry free.

These OEM batteries are hands down the best for my Panasonic G9 and my buddy's GH5. My bud has a couple of off-brand batteries that we both hate using; they have extremely poor battery life. These ones provide me with a sense of security and peace of mind when I'm out on a shoot because of their reliability and long battery life.I must say, since migrating to a mirrorless system from DSLR, I am spending twice as much on camera batteries than I have previously. I need 5 batteries for a mirrorless camera system to shoot the same amount that 2 batteries could get me with a DSLR system.If you're a casual shooter, sure, maybe try out the off-brand stuff. But if you're a serious shooter, your money is better spent on these, no question. I suggest buying them up on the rare occasion they go on sale.As for rating these for warmth, I can't say these provided much of that on those dreadful lonely nights ;)

I went through a series of aftermarket batteries for my cameras. Just buy original batteries, others may work well when you first get them but they will soon disappoint you. I produce videos for a living. When using a gimbal you have to balance the camera on the gimbal. When switching batteries from Panasonic to an aftermarket battery I was having to re-balance the gimbal because the aftermarket batteries are lighter than the original. What a pain in the @- -! Additionally the aftermarket batteries quickly fade to become nearly useless.
