Quality assurance community street lamp with lithium battery solar lamp agreement is 5 years

What do you mean warranty five years? Is on a contract to play word games, lithium battery is not obsolete within five years. Just capacity is becoming more and more low demand cannot be satisfied lighting time, just like our electric bicycle, can ride a 50 km at the beginning, only a year later

5 year warranty is what mean? Lithium ion batteries will not fail within five years, even though they are playing on the contract of word games. Just because the capacity is more and more low, we can't meet the requirements of illumination time. Just like our electric bikes, we can ride a 50 km at the beginning, after a year of only 20 km riding. Do you think what's the problem with the battery? This is beyond the scope of the warranty. 20 kilometers travel may not be able to meet your demand, so you need to replace the battery. The reason is the same. Guarantee the lithium battery life shall prevail, it is more practical. Lithium more strictly speaking, solar street lamps should be cycles. How much is the cycle count? For example, when a full charge, it is 12 v10ah, and load power consumption in a day is 12 v10ah, battery capacity will be consumed, and then fill is a cycle. Ordinary pure ternary lithium batteries ( The 12 v solar street light system the most commonly used in energy storage battery) There are about 300 - 400 cycle ( The theoretical service life of more than 500 individual cell cycle, because the battery voltage resistance is different, the cycle of the battery pack fewer) 。 If configured with the solar street light system, street lamp will need to replace the battery after 300 days. The length of battery life should be based on the quality of the battery core, huge huge capacity of the load and battery. For the same load, the service life of 12 v30ah and 12 v10ah is certainly different. Therefore, our solar street lamp manufacturers generally advocates customers appropriately increase battery capacity and realize shallow charging and light discharge. Although the cost may be higher in the early stage, but considering the entire life cycle of the solar street light system, it is more cost effective.
