A much better battery, twice the power that the 30's. Great price compared to Sony.

First battery sent didn’t work so well, a replacement battery sent and It works perfect. Customer service was spot on. I would purchase this battery again. I will be referring people here to purchase in the future.

Got 2 batteries fully charged the camera reads 291 minutes initially but ends up stopping at 2 hours 30 minutes just turned on which is 150 minutes

The D-Tap port it's just too big, the D-Tap won't be hold in place tried multiple ports.

UPDATE:Bought a 2nd one after very good performance from the initial one reviewed below.Discussion.It's been difficult to compare various aftermarket versions of the Sony BP-U60, because of the known tradeoff between capacity and the number of recharge cycles deemed to represent the total service life before replacement. Higher capacity batteries will deliver fewer instances of service from a full charge to depletion. The Sony batteries have relatively low capacity, but I still see acceptable service after 5 and 10 years. And when you factor-in the initial purchase price, a user must decide which aspect is the most important: Capacity, total service life, and cost.The Tanaka are among the highest capacity iterations of the BP-U60. I've got about ten charges on the first one, and the camera still shows a more than 300 minute run time on initial power-up. After ten charges on the rival Wasabi, the brand-new run time of around 250 minutes began to fall off, yet remains longer than the Sony. The Watson brand apparently has a quality control problem. When they work, they work. But they are the only brand in my experience to suffer a complete, unpredictable failure to hold a charge. It happened with two of four examples I have had. The Kastar are reliable, high capacity examples, but I've had two failures of the battery test LEDs. That does not kill the battery, but I have not seen that with other brands.These Tanaka are the first in my stock with the auxiliary output connections, as they and other brands start to include this feature. I have not tested either the USB or the D-Tap, but having the USB means no longer having to carry an external battery pack to recharge my smartphone in the field.Previous review continues.If your camera rig includes anything that is mounted in such a way that it comes close to the back of the stock Sony battery, you might have a clearance problem using this Tanaka. Camera brackets, light arms, custom-length cables would need an extra inch (apx) to accommodate the extended length of the Tanaka housing that has the D-Tap mount (and the USB power port). Just gave the first charge from new; will update with field use. Bright blue LEDs for power remaining, much easier to see than the LEDs on the stock Sony. Camera and battery exchange data properly. Seeing 300 minutes estimated run time at the start of Full Charge No. 1. Build quality and manufacturing tolerance seem good, with a tight snap onto the camera mount (good fit). Appearance shows nicely-finished seams on plastic housing, no burrs or deformities or discoloration on the contacts, and a back display panel that looks durable. Even the product label that shows the battery type mAH capacity is aligned well.If there is any warranty claim, it appears that your Amazon order, with the vendor information, is the only way to request satisfaction. Curiously, there are no "Tanaka" branding symbols or other commercial markings anywhere on the battery, nor is there any customer service information. The retail box is generic, using the old "MiniDV" reference to "Digtal Video," without any country of origin, customer service number, website URL, or anything to distinguish this Tanaka battery from very similar offerings with different brandings. A multi-language leaflet inside the box gives a standard warning against shorting the terminals, but does not contain anything to identify a retail company or vendor, or manufacturer. The retail box, with a flap to hang from a display hook in a store, comes packed in an outer cardboard box that also tells nothing about the source of the battery. I found this a bit concerning, but it may reflect a lack of sophistication about such details U.S. consumers have long expected.Hopefully, a user would never need to pursue a warranty claim during a reasonable life of the battery. But, safety advocates would have no way of tracking problems with this anonymous battery, especially given the history in the category of Lithium Ion meltdowns (thermal runway) and manufacturing errors (computer batteries).UPDATE: Capacity & running time prove goodI've now gone through about five use-cycles with this battery, and am finding the capacity good, the re-charge rate normal, and the running time about right for the rated mAh of this battery. My initial charge provided a 300 minute camera measurement "remaining time," and after the third cycle, that has risen to 310 minutes. This suggests there's some merit to the practice of conditioning a new battery with extended use and re-charging, rather than a partial use & re-charge that you might do later in the battery's life span.
