1. Do solar lights have batteries?

The answer is yes. Solar lights are usually equipped with solar batteries, solar batteries, including lead-acid batteries, nickel-metal hydride batteries and lithium batteries, lithium-ion batteries are more widely used in the solar lighting industry because of their high energy density and more stable working condition.

2. Why do solar lights need batteries?

First of all, solar lights work with less power consumption, if there is no solar battery, the excess power generated by the solar panel will have no place to store and be wasted, and the solar battery can be very good at this job.

Secondly, at night and no sun weather solar panels can not work properly, this time it is necessary to solar cells for solar lights power supply to ensure that the solar lights in the face of these circumstances can still work properly, which is very important for the stability of the solar lights lighting. In a word, solar battery is one of the important equipments to realize the self-sustainable power supply and night lighting of solar lamp.

3. Can solar lights use ordinary batteries?

Although it is true that solar lights can use ordinary batteries with matching voltage and current, it is not a long-term solution. First of all, ordinary batteries (such as daily alkaline batteries) need to be replaced regularly, although the price of solar cells is higher, but in the long run, the use of solar cells is much more cost-effective than the use of ordinary batteries, we should know that the life of solar cells is about 15 years, lithium iron phosphate battery life is up to about 25 years.

There is, ordinary batteries are not only far below the capacity of solar batteries, and ordinary batteries generally do not have charging capabilities, which makes the use of ordinary batteries to be much more trouble than solar batteries, so the use of ordinary batteries for solar lights for a long time is not favorable.

Finally, from the perspective of environmental protection, ordinary batteries need to be replaced frequently, which will produce a lot of harmful waste, for the environment is very unfavourable, so the use of solar batteries is a more environmentally friendly choice, can reduce the burden on the environment, and promote the development of human environmental protection.

4. How to replace the battery of solar lights?

4.1 Preparation

First of all, you should choose a sunny weather if you want to replace the solar light, because bad weather like rainy day will make it more difficult to replace the battery, and even cause safety accidents.

Secondly, you need to prepare tools such as wrench, screwdriver and insulating tape, which will be used when you replace the solar battery. Lastly, you need to equip insulated gloves and goggles, which will maximize your safety.

4.2 Turning off the solar light and opening the solar battery compartment

To make sure that you don’t get electrocuted during the replacement of your solar light you need to turn off the solar light and then use a screwdriver to open the solar cell compartment, taking care to keep the screws in place so that you can remove the old solar cells.

4.3 Purchase the same type of battery as in the solar light

Each solar battery has a fixed model, for example, the old solar battery working voltage and current is divided into 12V and 200mA, then you also need to buy the same model of solar battery to ensure that the solar light can work properly.

4.4 Replace the solar battery

Put the new solar battery into the solar battery compartment of the solar light, make sure the solar battery is in the right position, then close the solar cell compartment and use a screwdriver to tightly fix the cell compartment.

4.5 Startup Inspection

Turn on the solar light, if the brightness of the solar light is suitable and no abnormalities occur after running for a period of time, then the solar battery in your solar light has been replaced successfully.
