The charge has Output: DC 8.4 V, but the battery is 7.2 V. Is it Ok?

Yes, this is correct. When fully charged the batteries measure 8.4 V. When the batteries discharge halfway their voltage also gradually drops to 7.2 V. At empty, these batteries are about 6 V. To charge them back to full, you need to bring their voltage back to 8.4 V, hence the 8.4 V charger.

hmm- good question. I did not pay attention to that. I have been using the battery for a few weeks now and its working fine-holds a longer charge than the default camera battery that comes with camera from Sony.

I did not notice that either... my best educated guess would be that it can charge up to 8.4v, but will also be able to handle the 7.2v by automatically charging at a lower voltage... i could be completely wrong though... i bought this kit a few months ago for a sony handycam that i bought to record my engagement. the charge on the batteries lasts a long time! even if the charge hasn't been topped off recently. i charged both batteries when i first bought this and really only used and recharged 1 so far. i decided to pull the 2nd one out of my bag pocket and it still had full charge. it had only been like 2 months since it was charged last, but it was still fully charged... hope this helps.

I also have DC9700 charger and the battery charged without any difficulty. Also no idea what the difference would be with an A model charger.

7.2V - should last 90 minutes on a charge (one of the reasons why I purchased this)

I am looking at the unit CA-2421 and it says It DC 5V 2.1A. I also can it charges really fast.

I am pretty sure it is a 8v, when I received it it charged my HP tablet really well.

The charger can charge the 8.4v 1500mah battery. You may need to replace the chrger end with a matching large male end. The charger cable has enough leg the to cut and solder or crimp on a new connector.

My charger is labeled DW9107 7,2v - 14.4 v one hour charger. Output 2,8 amps DC

If memory serves, it was adjustable from ~11.8V to ~14.8V? I cannot remember exactly though (I have mine set for 13.8V to float charge)

I agree with Kevin. If you are concerned, check with the vendor. At this price, if it works out of the box an d charges to full capacity according to specifications, why would you worry?

Sure! It's a 12V battery, just not a big one. One caution, though. If you are using these in series (like, in a Razor scooter), you must disconnect at least one of the connecting leads between batteries. Otherwise, it's a 24V system, and your 12V charger won't work.

Hi Janie, I really can't say for sure. Output is important, this charger is 19.5v @ 6.7 A. Then plug obviously needs to be the same. If you send an e-mail address I'll send Picts of backplate and plug.

I had the same problem. So, I tested the battery with a multi meter and it tested at 4 volts dc. That was the condition it arrived to me in. I tossed it in the trash and bought an equivalent from RADIO SHACK. It tested at 12.3 dc volts. I hope this helps.

While I could certainly be mistaken, as an Electrical Engineer, I am fairly certain that there is some kind of DC-DC converter inside that is built out of solid-state components, and is thus fairly permanent. Without completely gutting and redesigning part of it, I would say that it is what it is. However, depending on the application, voltage outputs can change. Charging a drained battery may occur at 13.5 V for example while topping off a full battery may be somewhat higher. Why is it that you need it to be higher?

The part number on the battery is PA38a7U-1brs. DC 10.8V = 48Wh. As I said earlier, the sides have a grove to silde the battery into. Attahed R photos.

Im not sure. I received an 8 cell battery for a toshiba laptop and had to return it.

My charger, a ThruNite MCCC-4, outputs a charging level of 4.2v. When the battery reaches this level, shown onLCD panel, it shuts off, fully charged. The battery "likes" to hold an operating voltage of 3.5, so using a charging voltage of 3.8 would be conservative, and certainly safe. These batteries are very robust, and will not take more than they're designed for.

It is 7.4v with 2000mAh. It made too much power available. That's why it was redesigned to 7.2v with 1080. It won't hurt the electronics of the camera. The camera was designed for that kind of power.
