GNB front of the figure represents the number of single cells

Nickel-cadmium (Ni-Cd), nickel metal hydride (Ni-MH) rechargeable button batteries are usually combined into a battery pack, single battery usage is relatively small. General common nickel metal hydride nickel-cadmium button cell model that almost all types (except for military products). Combination of style more, we can refer to Guangdong Panyu Huali detailed description of the company to know about. China's domestic standard coin cell code called the GNB is the "nickel-cadmium flat" Pinyin first letter combinations; GNB front of the figure represents the number of single cells, GNB behind the figures represent capacity.

 Give you an example, 10GNB03 (one kind of special forces artillery laser rangefinder battery), is a button battery from the 10 GNB0.3Ah combined into appearance and D (One) battery exactly the same battery. After citing several examples of practical application of common,  mostly single cells 280K / H; handheld mini riot flashlight (that can be used in high-voltage discharge self-defense kind), which are mostly battery 4.8V button battery, most of them are 280K / H combinations; IPC above the reserve memory (also known as mixed CMOS) 3.6V button battery used, the most of 60K / H combination.

Button battery pack out of the factory using a special circular flange lug to spot welding, is to use a coin cell battery the same size and circular flange lug, to weld, so that the child does not appear to open the battery after welding welding, or the combined appearance of failure situation. More importantly, in the welding process, I know it is the battery voltage is higher than a one-time high, nominal 3.6V, fully charged can live 4V, self-discharge monthly average of about 10% less, no memory effect, but the capacity is small, probably for the same type of disposable lithium manganese button battery capacity of about 1/7.
