Rolls Battery has been manufacturing deep cycle lead-acid batteries since 1935. Experience gained has helped us achieve an unmatched reputation along with specific measures to obtain the maximum performance and life from our product. [. . . ] Please contact your retailer or Rolls Battery Company Limited to determine if the battery needs replacement.
Installation
Rolls offers batteries for a wide variety of applications. No matter the application, always be certain that the battery is properly secured, free of contaminants and that all connections are in good contact with the terminals. Contact your retailer or Rolls Battery Company Limited for additional information. Battery Orientation: Flooded lead acid batteries must be kept in an upright position at all times. Cable Sizing: The size of the cables used should be proportionate to the amount of amperage in your system. See Table 1 for maximum current carrying capacity based on cable gauge.

Top up or remove electrolyte as necessary for proper level. If necessary, clean with bicarbonate of soda and water (100 grams of soda to one liter of water). *Do not place on charge until electrolyte temperature is below 35°C.
Battery Charging
Table 2 – Charge parameters
Initial Charge
A battery may not be fully charged when received. Before this charging process, the cell electrolyte level should be checked. If this isn’t the case, add distilled water until all the plates are just submerged. [. . . ] The fluid should be 1/4 - 1/2 inch below the vent tube on each cell as shown in Figure 1. Carefully add distilled water to adjust the level if needed.
