When choosing a solar garden street light, how to judge the quality of the battery?

When choosing a solar lamp, judging the quality of the battery is mainly from the following aspects:

Battery type and capacity: Preferably lithium batteries, especially 18650 or 32650 models, pay attention to the actual capacity and business promotion is consistent. Regular products are usually marked with the capacity is actually attainable, to avoid the purchase of exaggerated publicity of the battery.

Battery brand and certification: Choose a brand guaranteed battery, check whether there are CE, RoHS and other international certifications, these certifications can ensure the safety and environmental protection of the battery.

Battery consistency: When multiple batteries are used in series or parallel, battery consistency is critical. The consistent battery pack can ensure the balance in the charging and discharging process of each battery and extend the service life.

Protection circuit: high-quality solar lamps should be equipped with battery protection panels to prevent overcharge and overdischarge, which is directly related to the life and safety of the battery.

Actual use test: If conditions permit, the battery life can be tested through actual use, such as observing whether the lighting time of the solar lamp after continuous cloudy days meets the demand.

Internal resistance: Batteries with low internal resistance can output electrical energy more efficiently and reduce energy loss, which can be detected by professional equipment.

Appearance and process: Check whether there is damage to the appearance of the battery, whether the terminal is firm, and whether the package is tight, which are the intuitive basis for judging the quality of the battery.

After-sales service: Good after-sales service is also an indirect indicator of battery quality, and quality brands usually provide longer warranty periods.

To sum up, when choosing a solar lamp battery, it is necessary to comprehensively consider the battery's specifications, performance, safety certification, brand reputation and practical application performance to ensure that the battery can reliably and permanently power the solar lamp.
