A battery may have a long-life span and be able to handle large loads, but it will have large and heavy or cost too much. A battery may be able to supply lots of power and be relatively small in size, but it will not have a long lifespan. A battery must therefore be chosen based upon the particular application. One type of battery will be appropriate for a portable radio and another type will be appropriate for storage in a PV system. Small-scale PV systems with batteries typically rely upon lead acid batteries as they are a good compromise between all of these different factors.
