Lithium battery 198tV should mean 19.8V, because t roughly means negative minus 10V, so 198÷10=19.8V, this group of lithium battery voltage is 19.8V. The 198tv of 20v battery is not the capacity mark of the battery, the voltage and capacity are not marked, there is no comparison, if it is the supplier's goods, as long as you look at the price, the capacity of the high price must be large.

Battery refers to the part of a cup, tank, or other container or composite container containing an electrolyte solution and a metal electrode to generate an electric current, and a device that converts chemical energy into electrical energy.
Lithium battery 168tV means that the lithium battery is 16.8V, 198tV means that the lithium battery is 19.8V, because t roughly means that it is negative minus 10V.

Lithium battery is a class of lithium metal or lithium alloy as a negative electrode material, the use of non-aqueous electrolyte solution of the battery. Lithium battery model specifications with a T battery, PCM in the battery is connected with a temperature-sensitive resistor, mainly used to monitor the temperature of the battery and PCM, and the temperature signal is transmitted to the load controller for processing, such as the battery and PCM temperature is too high, it is prohibited to charge and discharge.
