Aquaspray Pro 20L 45L water spray backpack battery replacement.
Compatible replacement battery for a Aquaspray Pro 20L 45L sealed lead acid battery from a UK warehouse at low costs.
Designed as a direct-fit replacement for the Aquaspray Pro 20L and 45L battery-operated water spray backpack, the 12V 10Ah battery is maintenance-free performance with a bit more stamina than the standard 8Ah model. Built using sealed AGM (Absorbent Glass Mat) technology, it provides reliable deep-cycle output with a focus on safety, stability, and long-term use in mobile water-fed pole systems.

Using AGM construction, the 6‑DFM‑8 resists sulphation, handles partial discharges better than flooded cells, and charges faster when paired with a suitable smart charger. The sealed design eliminates maintenance—no water top-ups, no acid spills, no mess. It’s a true plug-and-play upgrade.
To maximise lifespan, always charge after use, avoid leaving the battery flat for extended periods, and store it fully charged if unused for long stretches. For those working day-in, day-out with water-fed systems, the 6‑DFM‑8 offers both performance and peace of mind.
Battery Voltage: 12v
Battery Capacity: 10Ah-tall.
