The testing items of the new energy LED lamp battery after installation include installation quality, capacity test, internal resistance test and related technical information. These aspects will directly affect the operation and maintenance of the battery in the future.

When testing, first of all, you need to be fully familiar with the technical specifications of the parameters, structure, characteristics and other parameters of the battery under test. In order to safely and accurately complete the inspection after installation of the LED lamp battery, the most suitable battery test instrument can be selected for inspection, testing and comparison according to its existing equipment and technical conditions. The main test items are:

(1) Capacity test. Because this is based on the formal theory of the test, that is to say the current of the battery under test is discharged to the load for a specified time (Ah), determine its capacity to determine the position of the battery in the life cycle, this is The most ideal method. Newly installed battery packs must have capacity testing as part of the acceptance test.

(2) Power failure test. The battery is tested with the actual online load. Through the test results, an objective and accurate battery capacity and large current discharge characteristics can be calculated. When testing, as close as possible or meet the discharge current and time requirements.

(3) Measure the internal ohmic resistance. The internal resistance is the best indicator of the battery state. Although the internal resistance test method is not as absolute as the load test, it can detect at least 80%~90% of the problematic battery by measuring the internal resistance.

After the battery is tested normally, lift the cover and place it on the battery compartment. When placing the cover, avoid the sediment around the foundation falling into the battery compartment. Use a mixture of asphalt and fine sand (asphalt: fine sand = 1:3) to cover the cover and the cover around 40mm. When filling clay or triple soil, tamper once every 10cm, until it is 10cm above the ground.
