Sealed solar  batteries are divided into many categories, sealed lead-acid batteries, sealed solar liquid batteries, etc. Compared with them, lithium-ion batteries are becoming more and more popular because they are the power source of choice for electric vehicle manufacturers. The potential of lithium ions as an energy storage medium has not been fully explored, but it is promising.

  There are two types of lithium-ion batteries on the market. The first, and most popular with EV manufacturers, is the NMC (nickel manganese cobalt) chemistry type. The other is a LiFePO 4 (Lithium Iron Phosphate) type battery. NMC type batteries have high cycle life and are ideal for use in off-grid installations. LiFePO cells, on the other hand, perform exceptionally well at extreme temperatures and are suitable for use in extreme temperature regions.

  Lithium-ion batteries require little maintenance. They have a higher battery energy density. Because they have a longer life cycle, they have a longer life and a higher depth of discharge. Lithium-ion batteries can deliver 4,000 to 6,000 cycles at 80% depth of discharge and still last up to 15 years. But such batteries are expensive. They cost twice as much as lead-acid batteries with similar energy storage capabilities. At the same time, compared to the safety performance of lead-acid batteries, these batteries are also very fragile and require stable circuits to ensure safe operation.

Changshu Wanlong Power Technology R&D Co., Ltd. is a lead-acid battery manufacturer and storage battery manufacturer from China. The company sells 12v solar Gel batteries and sealed maintenance-free batteries all year round. The quality reaches the international standard and the performance is outstanding.
