Prolonged Cycle Life Gel Cell Deep Cycle Battery, 12V38AH Solar Power Deep Cycle Battery
12V38AH Deep Cycle Battery for Solar Power Gel Deep Cycle Battery Maintenance Free Gel Battery
Product Features
This series is designed for frequent cyclic charge and discharge applications under extreme environments. By combining the newly developed Nano Gel electrolyte with high density paste, the Solar range offers high recharge efficiency at very low charge current. The acid stratification is highly reduced by adding Nano Gel.
Product Structure and Working Principle
- Positive plate: Thick high Sn low Ca grid with high density paste
- Negative plate: Over designed capacity to overcome sulphation in low SOC
- Separator: Advanced AGM separator
- Electrolyte: Dilute high purity sulphuric acid with nano gel
- Battery container and cover: ABS
- Pillar seal: 100% factory tested, proven two layers epoxy resin seal
- Relief valve: Complete with integrated flame arrestor
