Since solar electronic products design concept is store small, unstable electricity generated by solar photovoltaic panels in to battery. Then supply stable power to Electrical equipment. Therefore, part of the energy storage is very important.Currently the storage medium is rechargeable batteries, there is also large-capacity capacitor to store electricity. The rechargeable battery is divided into nickel-cadmium rechargeable batteries, nickel hydrogen and lithium-ion batteries.

Nickel-cadmium batteries due to heavy metal contamination gradually be eliminated. Lithium from Sub-cell due to small size, high capacity have been widely used in solar charger. Since solar charger is different with the normal electronic products, the high quality  built-in battery  should be used.But this is easy to overlook the place where consumers, which is also some low-priced products key profits. In the market, a similar-capacity battery prices may differ by several times. Therefore, some manufacturers on the aim of the profits, lot of very low-cost solar chargers are used in secondary batteries refurbished battery.
Solar battery charger built-in lithium polymer battery should be better, compared to usual The most common lithium batteries (liquid lithium-ion), lithium-ion polymer batteries fitted into the gel, the level of activity is much smaller than liquid lithium-ion battery And therefore will not produce an explosion. And to apply to the use of solar energy charger environment through the heat-treated polymer battery is best to upgrade the battery temperature limits.
Finally, note that the product design, packaging and accessories.
