I bought myself for my Panasonic NV-GS (x) in the network a stronger second battery, having on the nameplate of a voltage of 7.4 Volt.
However, according to the original battery has printed 7.2 volts.
Can these 0.2 volt harm the Cam or the stronger battery can be safely used?

Antwort von Poldi:
When 0.2 V to harm a camera, then I would have no more words.
Antwort von StefanS:
In the original battery, it should be a Li-Ion Battery, equipped with 2 cells in a 3.6 V, the typical cell voltage of a Li-Ion Batteries.
In the spare battery is likely to be a Li-Ion Polymer Battery w / 2 cells a 3.7 V, the typical cell voltage of a Li-Ion Polymer Batteries.
Not all Li-Ion Polymer Batteries are offered as a Li-Ion Polymer Battery. Sometimes it stays for simplicity in LiIon, which knows the buyer now.
Right?
As I said, the 0.2 V difference do nothing.

Wrong! The spare battery is securely installed no LiPo, which cost about 3 times to 4, more than a LiIon!
7.2 V or 7.4 V is no preference. If only for marketing and only indicates the rated voltage, is with the run up to the Battery.
Small Battery Client: Li-Ion Batteries are used in a cell fitted with a rated voltage of 3.6 V each. 2 of them in series result 7.2 V, plus a few more in parallel increases the mAh. A Li-Ion battery has a Ladeabschlusspannung of 4.2 V, 2 cells have, therefore, 8.4 per Now it is so that a fully charged battery chamber is 8.4 V and then slowly lose s.Spannung. Only should be taken no 8.4 V, but just up the voltage from the battery. LiIon cells can have a rated voltage of 2.9 to 3.7, 3.6 are the ones with the Most Batteries.
Hope that was not too confusing.

Since the development of battery technology is also progressing steadily, is probably a small update installed.
Initially, it was indeed the case that a battery with a cell voltage of 3.6 V (x 2 = 7.2) was usually a Li Ion type, whereas with a cell voltage of 3.7 V (x 2 = 7.4) mostly Li Po guys were. The Li Po is more expensive, in fact, since the expected cost advantages over "conventional" Li Ion Batteries not set as expected. On Comparison of original types to 7.2 V No Name 7.4 V types, this difference is due to the pricing policy of the Manufacturer With its' original batteries lost. "
The difference between 3.6 V and 3.7 V does not result, as I previously thought the difference in Li Po Li Ion, but from the chemicals used for the cathode.
On pure cobalt-based types have a nominal voltage of 3.6 V and have a charging voltage of 4.2 V.
Nickel-cobalt-manganese-based types have a nominal voltage of 3.7 V and one charging voltage of 4.1 V.

The device is operated in the Battery, it is in fact something of no preference, whether as 7.2 or 7.4 V on it and is synonymous comes out. The battery operated charger is the perfect s.nicht, it is anything but no preference. The fact is dying a sure death earlier than necessary.
Resulting measurements under laboratory conditions, achieved that a battery of 3.7 V class if it is properly loaded to 4.1 V for about 800 charge cycles, this battery is charged, however, up to 4.2 V, is initially a slightly higher capacity, although he is dead after 300 charge cycles
So now most of the following happens:
If a device originally shipped with a 7.2 V battery and a Government-matching Charger / charging electronics of this right, of course, this instrument can be operated with one 7.4 V battery, without damage. The charge of the Batteries is, however, with up to 4.2 V (see above) and this brings about the maximum voltage sensitive 7.4 V battery faster than necessary.
Hope that was not too confusing :-)

But this is confusing. Read through it yourself again. I do not understand what you mean by that.
Have only your knowledge of Wikipedia? The "Chemistry for the cathode," suggests.

Do you have a link for this source? A Li-Ion Battery is synonymous to overload a different "effect" have.
If you ever replica of a Li-ion battery with Li-Po cells can find, let me know. When mine were previously only Li-ion cells inside. Buy dignity of such a replica battery once a couple of pieces still needed a few for my plane.

I'll try again.
If a device, no preference of any kind, an original battery included with Cobalt-based, which is compatible according to literature a charging voltage of 4.2 V, it is likely synonymous supply the 4.2 V power supply included, or on using the built-in electronic device, the charging voltage 4.2 V to be set. When I am with this adapter or the battery charging circuitry now has a load that does not tolerate the 4.2 V, such as a battery of nickel-cobalt-manganese-based mag which only 4.1 V, I was detrimental in the long run this Battery, with other words, the number of charge cycles decreases.

No, Wikipedia zero, nada, nothing, niente.
That the differences 3.6 / 3.7 V with the chemical and do not hang together with LiIon or LiPo, I had corrected some time ago in another thread on the same subject. But this time, just came from the synonymous information that had LiIon 3.6 V LiPo and 3.7. Later, in connection with the chemistry, I had to recognize that the distinction between LiIon and LiPo s.dieser body is too simple.
But of course I also researched on the Internet. Is not so easy because to date to stay, because the battery technology developed continuously. The points you sure as model pilots are better than me :-) and synonymous grateful for this My interest s.dem issue yet resulted from the first Game Boy years ago, when there were still 4 AA cells in it and I had to supply two of these things with a mobile power. They would have me, both with Batteries, as synonymous with wrong / badly treated Batteries driven out of business :-)
Incidentally, I have some information from your model synonymous sites that are on the field much better than the clippers or filmmaker who differ on this issue with a few exceptions, almost from the planet's level.
Current (currently always with due caution) the sources you can find here, for example:
The issue is very complex for pure users without knowledge of chemicals and laboratory in the cross indeed. I conclude that problems of understanding is not enough.
But collectively, we can say:
The device is operated sch ... no preference whether the battery has 7.2 or 7.4 V, the battery might not work.

I work at my SonyHC1 synonymous with the original battery 7.2 V and 7.4 V. As a second battery with the original power supply 8.4 V supply, the 7.4 V probably does not hurt.

Your Battery is not loaded with security with the power supply voltage! Before that always sits still a charge controller, the herunterregelt the tension. If you'd invite your battery with 8.4 volts, which would be a nice fireworks! In addition, there is a further tension between power supply and camera control electronics. For the internal electronics today is running with 3.3 V / 1.8 V!
Again, to summarize:
Original Battery 7.2 V - 7.4 V Battery Additional: The additional battery is loaded with too high voltage! => Charge cycles decrease dramatically!
Original Battery 7.4 V - 7.2 V Battery Additional: The additional battery is loaded with too little excitement! => It does not hurt, although the battery, but the capacity decreases by about 8%.
