Excellent quality. Batteries work as they should. Great pricing. Allows me to not have any anxiety in regards to shooting my Sony M6 on locations.

I've been using these for a year now, pretty heavily, with no problem. I don't notice any difference in battery life from the original Sony battery, nor have I seen any fall-off in battery life with repeated use. The charger works fine, even with the Sony battery, and being able to charge two at once from any USB power supply, especially in the car, is very convenient.

Works great, as advertised. Battery power is great all beit a half hour.

I’ve depleted three of the four batteries so far, and I am pleased with the results for the price. Each took about three hours to fully charge using a 1V charging outlet. I chose the slower method as not to overtax the batteries on their initial charge. I’m sure I could use the higher voltage outlet next time. Below are the discharge results using the Sony MV1 camera: Battery 1 - 2hr. 20min. - Video, internal mics. Battery 2 - 2hr. 13min. - Video, external mic. Battery 3 - 2hr 40min. - Video, internal mics. Battery 4 - 3hr. + - Audio only...battery still has charge after 3hr. While not as good as a genuine Sony, the fact that you have four batteries for about the same cost as one original is fantastic. There is also a wide margin for how long the batteries seem to last under what conditions. I can’t account for longevity, obviously, but so far I have gotten a LOT of use. My next step is to get a capture card to use this camera for streaming and video podcasting. For the price, I can’t complain. I could have spent more and gotten a genuine replacement and only added 3.5hr to my runtime, so this, so far, has been a pretty good deal. Haha

Live these, they last long and the charger is a pleasure to use

Already had a charger, but the batteries were more powerful than the ones I had and did what they were supposed to do. My other charger works fine with them also since it seems a little better than the one supplied with these.

I mean, at this price, you can be in the field on a shoot and know that you have more than you ever need. I timed these and the run my small CX 405 for 1.5 hrs. So this Batmax 4-pack will give you 6 hrs of power. Add that to the batt(s) you already have and you can rest easy and focus on the footage rather than the batt level indicator. You know you want 'em! And the charger will charge 2 at a time. Unbelievable price.

This package fits the bill and the price is right. I compared the battery life with the original Sony battery in my RX100 M7 and the run time was very similar. The ability to charge two batteries at the same time is very important to me when I travel. I use a USB power bank to charge batteries in the field if they run low. Love the plastic cases that are included.
