Alpine offers a wide variety of battery water level indicators. Watering level monitors dramatically improve battery maintenance by intelligently alerting personnel when a battery needs water — and when it does not. These level indicators allow watering on a labor-saving “as-needed” basis instead of a hit-or-miss schedule. Watering too frequently can cause electrolyte boil overs, which reduce battery capacity by three percent for each occurrence. Lack of water in batteries creates a low electrolyte level, eventually causing permanent damage to the cells.
