Product Details:

Solar street lamp battery is the application of the battery in solar street lamp, solar street lamp battery role is to store the solar cell components of electricity generated,
When the light is insufficient or at night, another new energy street lamp is illuminated.
Currently used solar street lamp battery:
Sealed lead-acid batteries, ordinary lead-acid batteries, gel batteries, lithium iron battery and alkaline nickel cadmium battery, the voltage is generally for 12V or 24V.
But the most commonly used is the sealed lead-acid batteries, colloidal batteries, which are due to their maintenance free, and high environmental protection is widely used.
For solar street lamp battery should be equipped with: the number of circulating charge and discharge is enough, self discharge rate is low, long service life, deep discharge ability, high charging efficiency, can be less maintenance or maintenance free

The calculation method of the solar street lamp battery configuration is as follows:
One: first calculate the current:
Such as: 12V battery system;
30W lamp 2, a total of 60 watts.
The current =60W / 12V=5A
Two: calculate the battery capacity needs:
Such as: street lamps per night, the total lighting time required for full load 7 hours (H);
(such as 8:00 open at night, the night 11:30 to close the road, 1 am 4:30 open 2 Road, the morning 5:30 closed)
Need to meet the lighting needs of 5 days in a row. (5 days before another night of rain, 6 days)
Battery =5A * 7h * (5+1) days =5A x 42h=210AH
In order to prevent the battery from overcharge and overdischarge of battery charging, generally to about 90%; the remaining 20% or so discharge.
So 210AH is only about 70% of the real standard in the application.
