RECHARGEABLE BATTERY 12V 1.2AHMulti cell design for economy of installation and maintenanceLow self-discharge rateUse in any positionThe valve regulated, spill-proof construction of the Polmar battery allows trouble-free, safe operation in any position. There is no need to add electrolyte, as gases generated during over-charge are recombined in a unique "oxygen cycle". Polmar batteries use state of the art design, high grade materials, and a carefully controlled plate-making process to provide excellent output per cell. The high energy density results in superior power/ volume and power/weight ratios.Low internal resistance allows discharge currents of up to ten times the rated capacity of the battery. Relatively small batteries may thus be specified in applications requiring high peak currents.Special separators, advanced plate composition, and a carefully balanced electrolyte system have greatly improved the ability of recovering from excessively deep discharge.Batteries may be used in series and/or parallel to obtain choice of voltage and capacity.Due to recent design breakthroughs, the same battery may be used in either cyclic or standby applications. The high watt-hour per dollar value is made possible by the materials used in a sealed lead-acid battery: they are readily available and low in cost.this batteries may be discharged over a temperature range of -20°C to +50°C (-4°F to + 122°F) and charged at temperatures ranging from 0°C to +40°C (32°F to +104°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 case materials impart great resistance to shock, vibration, chemicals and heat. A low self-discharge ratepermits storage of fully charged batteries for up to a year at room temperature before charging is required. Lower storage temperatures enhance shelf life characteristics even further.
