         Mostly,we use lead-acid battery and lithium battery in outdoor solar street lights,So what is the difference between lead-acid battery and lithium battery in outdoor solar street lights? solar panel led lighting system

      1.The durability for automatic solar street light battery: lead-acid batteries generally deep charge deep discharge within 800 times, there is memory, life expectancy is about five years. And there is liquid in the lead-acid battery. After a period of consumption, if the battery is found to be hot or the charging time is short, the liquid needs to be replenished; the lithium battery has strong durability, slow consumption, up to 2000 times of charging and discharging, and no memory. The general life expectancy is about 8 years;    

   

      2.The volume and quality for automatic solar street light: the general lead-acid battery weight is 16-30 kg, the volume is larger; lithium battery is generally 2.5-3 kg, the volume is relatively small, so transport is light, easy to carry; 3.The price and warranty period for automatic solar street light: the current mainstream battery on the market is 12V and 24V, if replaced, lead-acid battery 450 yuan, the warranty period is 2 years; lithium battery price is relatively expensive, need about 1,000 yuan, but the warranty period For 3 years;

       4.The usage time for automatic solar street light: The discharge depth of the lead-acid battery is 50%-70%, and the discharge depth of the lithium battery is 100%. This means that 30%-50% of the electricity generated by the solar panels must be present in the lead-acid battery and cannot be used. The same 24V battery, in the case of full charge, the lead-acid battery solar street light works 24 hours, the lithium battery solar street light can work 36 hours or 48 hours.

      5.The battery capacity for solar panel led lighting system: lead-acid battery capacity is about 20 amp; lithium battery capacity is 8-10 amp;

     6.Environmental protection for solar panel led lighting system: Lead-acid batteries are polluted during the production process. If they are not properly recycled, they may cause pollution; lithium batteries are relatively green.
