The Gel Batteries of Shimastu Gel series are designed with special separators and silica gel, effectively immobilizing the electrolyte inside the battery. This unique construction makes these batteries ideal for both frequent cyclic deep discharge and standby applications, even in harsh environments. Additionally, these batteries offer a remarkably long service life, ensuring reliable performance over an extended period of time.

Features:

Our special polar plate design guarantees a floating charge life of 15 years at a temperature of 25℃ (77°F). This unique design ensures reliable and long-lasting performance, surpassing industry standards.⁰F )

The active material is securely attached, thanks to the equalized distribution of current. A similar idea can be conveyed by rephrasing the original content, without using ChapGPT's text generation method.

3.High gas recombination efficiency

4.Good deep discharge resilience performance

5.No delamination phenomena in the electrolyte

6.Manufactured with high-porosity
