What are the backup batteries of Lishi? Is it the largest battery manufacturer in China?

Landlord, your question is too broad.

The spare batteries of Lishi are generally divided into pure lead batteries, AGM valve-regulated sealed lead-acid batteries, valve-regulated sealed colloidal lead-acid batteries and tubular colloidal batteries (OPzV series).

Pure lead battery has high energy density, combined with the most advanced thin plate, pure lead technology and compact assembly structure, which ensures the service life of the battery. The design of pure lead thin plate strengthens the cycle durability and floating corrosion resistance, and has strong fast charging ability.

AGM series valve-regulated sealed lead-acid batteries are widely used in communication systems, power systems, emergency lighting systems, automatic control systems, fire and safety alarm systems, solar and wind energy systems, computer standby power supplies, portable instruments, meters, medical system equipment, electric vehicles, power tools and so on.

Based on the long-term unremitting research and development of VRLA battery (AGM diaphragm), LEOCH colloidal battery was successfully developed by relying entirely on its own technology and strength. The simulation acceleration test shows that the effect is good, the quality index of Leoch colloidal battery has reached the advanced level abroad, and serial production has been realized.

Tubular colloidal battery: Self-discharge is extremely low, made of high-quality materials, with monthly self-discharge rate ≤ 65,438 0.5%, colloidal electrolyte, large heat capacity, good heat resistance, suitable for harsh environment (40~60℃), excellent cycle performance and deep discharge recovery ability, no need to replenish water for maintenance, gas recombination efficiency higher than 95%, long service life and floating charge design life of 20 years. Excellent sealing performance, no gas leakage, no pollution to the environment, excellent safety performance of environmental protection products, special separator, copper electrode with high porosity, low resistance and low internal resistance, ensuring safe discharge of large current, without heating, uniform distribution of solid gel electrolyte concentration, no delamination, high product reliability, fire-proof and flame-retardant safety valve, effectively preventing external open flames or sparks. I won't say anything more specific, so please refer to it.
