Size
Size is one of the basic factors to purchase a battery. The size of Lead acid battery is bigger in compared to C-cell battery. AA, AAA and 9V are standard sizes, available for battery users.
Power density and weight of batteries
These factors can cause a difference to the performance of batteries. You can find higher level of power density with the high quality batteries. However, while you focus more on weight, it is better to choose the lightweight batteries. Energizer AAA lithium batteriesare lightweight products, useful for a variety of devices. Their weight is 1/3 less than regular alkaline batteries
Re-usability of batteries
For the non-rechargeable batteries, you have to dispose of the cells after using the energy fully. However, while it is a rechargeable Energizer AAA battery, you can recharge it more than 100 times.
Voltage of your battery
The chemistry is the most important factor to affect the battery voltage. For instance, lithium batteries are mostly 3V cells, while the lead acid ones are available as 2V batteries.
You can check out other additional features of a battery. You need to know whether the batteries keep up their performance under any temperature.Energizer batteries have also leak-proof construction, causing no problem due to the leakage of chemicals to the devices. Thus, these innovative technologies make the batteries more reliable.
