In my rare device uses a battery of this size D. Type D as I remember, most large format batteries, bigger is simply no, finger batteries. I have these batteries needed for the newfangled fly swatter, ingenious products in China. Flyswatter works on the principle of electric shock, and I must say works well, but more on that another time.
These batteries I saw in the near hardware store, where they decided to buy them. Although these batteries for my feelings probably the most counterfeited batteries for almost any Chinese market, these Panasonic batteries of all types is just a sea. But like the instance is made in Poland, according to the label 
In comparison with other formats batteries, battery capacity Panasonic D format I think will be the biggest, although it must conduct tests and measurements, since much depends on the technology used in the elements. But this has not gotten ...

My small and slim remote control at the unit eats only thin battery form factor CR2025. By the way, and computers are used almost the same battery. As usual, had to buy a battery once the board has ceased normal switch. On this occasion I am reminded of the type anecdote "And you are also stronger push the button on the remote when the batteries sit in it?" Вобщем without the remote was bored and in the near hozmage find products company Camelion. Products of this brand is already a bit familiar to a modest audience like me, so I bought without having to worry that they will stop working after a couple of days. And as it turned out not in vain, because the products produced under the control of "CAMELION Batterien GmbH", which has roots in Germany, and the quality of German products to tell I think not. I could not measure the initial voltage of 3 volt battery. It amounted to 3.13 volts, which gives hope for a bit longer battery life. Incidentally, the batteries CR2025 virtually interchangeable with the elements CR2032 - but they are just as thick, and naturally have a slightly higher capacity. However, here we must check whether they vlezut in the battery compartment.
Battery CR2025, features:

Battery type: Lithium
Form Factor: CR2025
Interchangeable analogues: DL2025, 5003LC, E-CR2025

You know what it looks like stranded in the multimeter battery? Very interesting. Take any battery and a multimeter measure the voltage. So unless the multimeter battery is stranded, the readings will show that the measured battery voltage is increasing before your eyes! Maybe you can even skip the tricks with this tseshkoy Вобщем, a multimeter battery is 9v, so I had to buy a new one, and unlike the previous incomprehensible manufacturer, this time I decided to buy a proven brand Dyurasel. However, due to the fact that the measure had nothing, I was left in the dark, how many volts primary voltage in a battery. Then, as any check required.
Вобщем, nothing special:
Duracell Battery
Voltage: 9V
Form Factor: 6LR61 MN1604 or
Technology: Alkaline
Batteries of this size nowadays used less and less to the same standards for small batteries AA and AAA are not much cheaper, and sell them more And yet, I'll have one such battery, because there are hours old, and they are calculated on a standard size battery as R14. Since the format of C is not very popular, and choice in the store was not great - one type of battery In principle, the GP brand enough established itself as a good manufacturer, and do not trust him there was no reason, and I bought a set of batteries GP. In contrast to the high-capacity batteries Energizer batteries GP showed a normal nominal starting voltage - 1.51 volts. Вобщем, miracles course of such a cell is not worth waiting, but nonetheless, I think working hours will be long enough.
Taking this opportunity, and bought batteries Duracell TURBO, to check them. As expected, the initial voltage of 1.60 volts. Incidentally, the battery pack dyurasel stated that you should not set both old and new batteries. But do not write why, but from my own experience I know that if you do so, then the new battery will end very quickly They are considering to hold an expanded test, the batteries in a flashlight and see what will allow him to shine for longer and know the real capacity of the batteries dyurasel
