After a few years, I thought it was time to retire some of my old Sony NPF-970 batteries. You start to notice that they won't hold a charge as long, and taking them out in the field was always questionable. After shopping around, I stumbled on to the SWIT S-8972 Batteries. The only Sony NPF style battery I know with a built in meter! I can't tell you how something so simple could really make life a whole lot easier.

Ok, so the battery meter is huge in my book, but there's more to the SWIT S-8972. It also offers a DC output allowing you to simultaneously power another device. Do you even know how many video devices there are that could benefit from this? Maybe you've got a monitor that runs on Canon LP-E6, but now you can optionally power it with the SWIT. An LED light? Audio recorder? Or how about taking a Sony Dummy battery and using the SWIT as your power source to power your Sony A7sII A7RII (or compatible sony camera).

In any case, you could buy cheaper batteries and i'm sure they will last a good while. But for a few more bucks, I find the built in Battery Meter and 7.4V DC Output is worth the extra cost. You can find the SWIT S-8972 product page (here).

I'm pretty happy Canon continued to support the LP-E6 battery with many of their camera models. It helps to be able to keep things uniform. I've had about 6 aftermarket LP-E6 batteries that i've been using for my Canon 5D Mark II & 7D shown in this video here: https://cheesycam.com/canon-5d-mark-ii-7d-cheap-china-batteries/. I'm a big fan of these batteries and have used them for quite a while without a hiccup. The problem was that when these were first released, they didn't have the option to show battery life on the camera due to a special information chip. It's about time I grabbed some additional batteries and if i'm not mistaken the new Canon 60D on order will also be using the LP-E6 battery type. Now that i'm in the market for some extra batteries, these newer LP-E6 aftermarket batteries are already chipped properly to show battery life with the Canon DSLR's. Here's the link to the proper LP-E6 aftermarket batteries that should read proper battery life with your Canon DSLR's. Canon 5D Mark II & 7D batteries chipped to show Battery Life.

Opteka has been a fairly reliable name in the DSLR community providing cheap alternatives, so if you're an Amazon shopper here's a chipped Opteka LP-E6 2400mAh Ultra High Capacity Li-ion Battery Pack for the Canon EOS 7D & 5D Mark II Digital SLR Camera (Fully Compatible)
