EXPEDITION Plus Ultra Deep Cycle GEL 12 V 250 Ah Battery (EXP12‑250C)
For installations requiring the highest capacity in the Expedition range, the 250 Ah lead‑carbon GEL battery provides long‑duration power and the same fast‑charging, long‑cycle performance as smaller models. The battery uses activated carbon and graphene on the negative plate to combine lead‑acid chemistry with super‑capacitor behaviour, giving more than 1 500 cycles at 50 % depth of discharge.
Like the other Expedition Plus GEL batteries, it is completely sealed, maintenance‑free and resilient to partial state‑of‑charge use. It can re‑charge up to ten times faster than a conventional lead‑acid battery.
Features
- 99 % high‑purity lead‑carbon GEL technology.
- Sealed, unspillable and maintenance‑free design.
- Resistant to sulphation and partial state‑of‑charge operation.
- Super‑fast charging and high energy density.
- Over 1 500 cycles at 50 % depth of discharge.
- Terminals at one end; bolt‑through terminals (Type 2).
- 5‑year limited manufacturing defect warranty.
