reached, the product will be charged at the highest voltage point unl the
current is reduced to below 3A or the me exceeds 3 hours.
5.5 Float charging: Float charging is started aer constant voltage charging, but
charging voltage and current are smaller; it is maintenance charging and
allows a longer me of safe charging. By float charging, the baery can be
charged to nearly 100%. Too small current is not enough to make up for
self-discharging of the baery, while excessive current will lead to
overcharging and dehydraon; small current
charging for a long me can
eliminate sulfuraon of negave plate.
5.6 USB output: This product has two USB output interfaces, the output voltage is
5V, and the maximum current is 3.4A; smart idenficaon of the terminal
device is available.
