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.

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.

The batteries will only give about an hour or 2 or charge before being dead. I don't think its an issue with crappy batteries though as the Sony battery does the same thing and I do have the camera configured for Max quality. Might just be the way it is. I will say it was nice to see all the batteries came with a plastic case. The instructions for the charger are great. Don't forget to unplug when done charging batteries. Charging time, I can't say as I just plug it in and go to bed. But everything appears good and high quality.

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

Fit like a charm in my Sony camera. As a fire inspector I can burn through batteries and this was a economical choice over buying more from Sony. I think they might actually last longer between charges although I haven’t down a side by side comparison with a timer. Buy them, you won’t be disappointed.

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

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.
