ALL Batteries come in all shapes and sizes and there could be as many types as there are species of we distinguish batteries by chemistry, voltage, size, specific energy (capacity), specific power, (delivery of power) and more. A battery can operate as a single cell to power a cellular phone, or be connected in series to deliver several hundred volts to serve a UPS (uninterruptible power supply system) and the electric powertrain of a vehicle. Some batteries have high capacity but cannot deliver much power, while a starter battery has a relatively low capacity but can crank the engine with 300A.
The largest battery systems are used for grid storage to store and delivery energy derived from renewable power sources such as wind turbines and solar systems. A 30-megawatt (MW) wind farm uses a storage battery of about 15MW. This is the equivalent of 20,000 starter batteries and costs about $10 million. One mega-watt feeds 50 houses or a super Walmart store. Let’s now examine each of the battery characteristics further.The imprinted voltage refers to the nominal battery voltage. Always observe the correct voltage when connecting to a load or a charger. Do not proceed if the voltage differs. The open circuit voltage (OCV) on a fully charged battery can be slightly higher than the nominal; the closed circuit voltage (CCV) represents the battery voltage under load or on charge and the readings,Specific energy or gravimetric energy density defines the battery capacity in weight (Wh/kg); energy density or volumetric energy density is given in size (Wh/l). A battery can have a high specific energy but poor specific power (load capability), as is the case in an alkaline battery. Alternatively, a battery may have a low specific energy but can deliver high specific power, as is possible with the supercapacitor. Specific energy, we carry the finist High Performance Batteries,
