Solar street lamp battery is the application of battery in solar street lamp. The function of solar street lamp battery is to store the electric energy generated by solar cell modules.When the light is insufficient or at night lighting of another new energy street lampCurrently, solar street lamp batteries are:Sealed lead-acid battery, ordinary lead-acid battery, colloid battery, lithium iron battery and alkaline nickel-cadmium battery, the voltage is generally 12V or 24V.But the most commonly used are sealed lead-acid batteries, colloidal batteries, which are widely used because of their maintenance free, and high environmental protection.

For solar street lamp battery should have: cycle charge and discharge times enough, low self-discharge rate, long service life, strong deep discharge ability, high charging efficiency, can be little or no maintenanceThe calculation method of solar street lamp battery configuration is as follows:First, calculate the current:Such as: 12V battery system;Two 30W lamps with a total of 60 watts.Present current = 60 w 12 v = 5 aSecond: calculate the battery capacity demand:For example, the cumulative lighting time of street lamps should be 7 hours (h) with full load per night;(such as 8:00 PM, 11:30 PM, 4:30 am, 5:30 am)It needs to meet the lighting requirements for 5 consecutive cloudy and rainy days.(5 days plus lighting of the night before rainy day, 6 days)Battery =5A×7h×(5+1) days =5A×42h=210AHIn addition, in order to prevent overcharge and overdischarge of the battery, the battery is generally charged to about 90%;Discharge margin of about 20%.So 210AH is only about 70% of the true standard in the application.
