This battery is designed to work with our twin-panel solar pond pumps and fountains, excluding the single-panel SP25 model. Before purchasing, please thoroughly review the product details provided as there may be important restrictions to consider. For any queries, feel to reach us either via email or phone call.

Our solar pumps typically operate at an 18V capacity. However, with this battery in use, they operate at 12V. Consequently, this reduces the maximum head from approximately 10 feet to 6 feet, and the Gallons Per Hour (GPH) by approximately one third. The term "maximum head" refers to the distance from the water surface to the peak location where you aim to position the waterfall.
With optimal sun exposure, the battery may require 1-2 hours for a full charge. Once fully charged, it can power the pump for an estimated 6-8 hours after sunset. If there is a lack of sufficient sunlight, the pump will not operate, and the battery will not charge. These results may vary depending on your geographical location and the season. If you require further information or assistance, please contact us at 855-723-3564. We are here to ensure this battery fulfills your requirements.
The built-in lead-acid battery should offer between 300-500 days of usage before needing replacement, which typically costs around $125, inclusive of fees. Alternatively, the lithium version, while lighter, is expected to last for at least three years before replacement is necessary, costing approximately $165.
