The Shimastu Gel series Gel Batteries have been designed with specialized separators and silica gel that immobilizes the electrolyte within the battery. These features make the batteries ideal for applications that require frequent cyclic deep discharge or standby in harsh environments. Additionally, the Shimastu Gel series Gel Batteries have an extended lifespan, ensuring that they can be used for an extended period. Overall, these batteries are an excellent choice for those looking for reliable, long-lasting batteries for their equipment and devices.

Features:

1.Special polar plate design,which ensures a designed floating charge life of 15 years at 25℃ (77 ⁰F )

2.Equalized current distribution, the active material is not easy to fall off

3.High gas recombination efficiency

4.Good deep discharge resilience performance

5.No delamination phenomena in the electrolyte

6.Manufactured with high-porosity
