This product mainly uses lead‐acid batteries. Other types can also be used such as
nickel‐cadmium (Ni‐Cd), Ni‐MH, Lithium‐ion (Li‐ion) and other secondary batteries.
Basically, lead‐acid batteries can be divided into two categories: one is flooded lead‐acid battery;
the other is the sealed lead‐acid battery. Their differences are: the former will continuously
produce gas which will be directly emitted from the battery during charging, so one must replenish
water periodically; the latter is less efficient at its positive electrode during charging, so the oxygen
produced in the earlier stage of charging will be used to suppress the production of hydrogen in
the initial charging stage. In other words, the oxygen produced from the positive electrode during
the charging process is absorbed directly and thus reacts with the surrounding electrolyte naturally
so that the negative electrode is reduced back into lead sulfate, which is the original product during
discharge.
Because the sealed lead acid battery is intrinsically maintenance free, today's electrical vehicles
­ ­
use the latter as the lead acid batteries. Although lead acid batteries are not so ideal in power ­ ­
density and energy density and its lifespan is limited, the lead acid batteries a ­ re the mainstream
batteries currently due to the low cost, better instantaneous discharge capacity, more mature
development and technology, etc. This type of battery requires a higher voltage to charge the
battery completely. While using this type of battery, please remember to set the related charging
parameters through the software so as to maximize the benefits of the battery. Please contact the
battery manufacturer to obtain the recommended setting values.
