Knowing the technical features of batteries
The voltage level of one cell is 1.5V. However, you can increase the voltage with the connection of various other cells. Thus, you have to add those voltages together to get the higher output. Ampere-hours indicate the rate of discharge of the batteries. Ampere is the current supply level of the batteries. By knowing these technicalities of your battery, you will be able to buy the right product for your device. However, remember that the discharge rates of various batteries may be different. When you are buying 1.5 Volt L91 AA Lithium Battery of Energizer, you have to find out the details of its discharge rate.
Capacities of various batteries
1.5V batteries are also available in various other sizes- C, D and AAA. However, the ampere-hours or capacity of all these batteries is different. For instance, in case of 1.5V AA batteries, it is 2.850ampere-hours. For 1.5V AAA batteries, it is almost 1.150 ampere-hours. Thus, you can find the difference in the performance level of all the batteries.
However, 1.5 Volt L91 AA Lithium Battery of Energizer offers you superb performance. This battery lasts seven times longer than that of other batteries.
