How long the Solar garden lamp post lights can be used is closely related to many factors. Among them, the battery is the main factor. The quality of the battery directly affects the length of time the garden light can be used.
At present, there are two main types of solar cell packaging, laminated and glued.
The lamination process can guarantee the working life of solar cells for more than 25 years. Although Epoxy is beautiful at the time, the working life of solar cells is only 1 to 2 years.
Therefore, low-power Solar garden lamp post lights below 1W can be used in epoxy packaging without excessive life requirements.
For solar lamps with a specified service life, it is recommended to use a laminated package. In addition, there is a kind of silicon gel used to encapsulate solar cells with glue. It is said that the working life can reach 10 years.

Because the input energy of solar photovoltaic power generation system is extremely unstable, it generally needs to be equipped with a battery system to work, and solar lamps are no exception, and batteries must be configured to work.
Generally, there are lead-acid batteries, Ni-Cd batteries, and Ni-H batteries. Their capacity selection directly affects the reliability of the system and their price. The selection of battery capacity generally follows the following principles: First, under the premise of meeting the night lighting, During the day, the energy of the solar cell modules is stored as much as possible, and at the same time, it must be able to store the electrical energy that can meet the lighting needs of continuous rainy days at night. The battery capacity is too small to meet the needs of night lighting. The battery capacity is too large. On the one hand, the battery is always in a state of power loss, which affects the battery life and causes waste.
How to choose the battery for solar lights
1. The battery should be a sealed lead-acid battery. The battery should be maintenance-free and recyclable. It can be recycled for at least 1500 times. It can work normally in the temperature range of -20℃–50℃ and guarantee a 5-year service life.
2. The battery should be able to work continuously for 3 rainy days, at least 5-8 hours of electric light capacity every day, and only use solar energy with an average of 10% of the power
3. The battery is placed at the bottom of the light pole to avoid sun exposure and separate from the solar panel to avoid heat exchange with the solar panel. At the same time, the battery should be airtight and ventilated to prevent rainwater from spreading over the two electrodes and causing permanent damage to the battery.
It can be seen that, as far as possible to choose the solar cell closed form, and the battery capacity is also ideal battery, and also need to use the solar garden light in a scientific and reasonable way, you can extend its use time.
