The Shimastu Gel series Gel Batteries excel in their manufacturing process by utilizing unique separators and silica gel to immobilize the electrolyte within the battery. They are particularly suitable for demanding environments, making them ideal for frequent cyclic deep discharge or standby applications. Additionally, these batteries boast an impressive longevity, ensuring a prolonged service life.

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
