The valve regulated, spill-proof construction of this battery allows trouble-free, safe operation in any position. There is no need to add electrolyte, as gases generated during charging are recombined in a unique “oxygen cycle”.
Dependable service life can be expected under normal operating conditions. Low self-discharge rate allows for storage of fully charged batteries for longer periods of time before charging is required.
Lower storage temperatures will further extend shelf life. Maybe discharged over a temperature range of -40°C to +60°C (-40°F to +140°F), and charged at temperatures ranging from -20°C to +50°C (4°F to +122°F). The high-impact resistant battery case is made either of non-conductive ABS plastic or styrene. Large capacity batteries frequently have polypropylene cases, all of these materials impart great resistance to shock, vibration, chemicals, and heat.
