FAQ for Solar Light Batteries
- How do solar-powered streetlights work?
- Solar streetlights work by converting solar energy into electric energy. The solar panels mounted on the pole of a solar street light absorb solar energy in the daytime, which then can be converted into electricity. And built-in rechargeable batteries play the role in storing electric energy. The light will work on electricity if needed.
- Do outdoor solar lights need batteries?
- Generally, Solar lights are built-in with rechargeable batteries. Outdoor solar lights do not actually power on solar energy, but rather on the electric energy stored in rechargeable batteries, which are recharged by miniature solar panels.
- Can I use a higher mAh battery in solar lights?
- Using a higher mAh battery enables the battery to work for a longer time at night. It’s necessary for you to consider the voltage and the size of the battery, which should match exactly the original solar light batteries.
- Why do I have to use rechargeable batteries for solar lights?
- What a solar light needs to power is not just solar power, but also a battery, which is required to be rechargeable and thus can be recharged by solar panels, to store the electric energy converted by solar energy. The electric energy is stored for later use to prevent power blackouts.
- What kind of batteries are used in solar streetlights?
- Li-ion batteries are generally used for all-in-one lighting systems such as solar street lights and solar garden lights. A higher energy density makes lithium-ion batteries lighter and smaller than other batteries such as NiMH batteries and Ni-Cd batteries when in the same battery capacity. Besides, lithium-ion batteries are comparatively low maintenance and don’t require scheduled cycling. Lithium-ion batteries also have a low self-discharge rate and a long service life.
- How often do you need to recharge a solar light battery?
- A solar light battery will self-discharge over time, and stop to work finally if not recharged. Generally speaking, Solar light batteries need to be recharged every 3 months, which will keep the batteries functioning well.
