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 needed one such battery, because there are hours old, and they are calculated on a standard size battery as the 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.
