The Shimastu Gel series of Gel Batteries boasts a unique manufacturing process that uses specially designed separators and silica gel to immobilize the electrolyte within the battery. This makes it an ideal choice for applications that require frequent cyclic deep discharge or standby in challenging environments. Additionally, this battery has an impressive lifespan, ensuring that it will remain reliable for years to come.

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
