PowerSonic 12V 28Ah lead acid battery PS-12280

• Waterproof, maintenance-free
• The valve-regulated and sealed construction allows safe and trouble-free operation in any position, except continuous use in the upturned position. The sealed system eliminates electrolyte control and the addition of water. The gases generated are recombined internally during normal use.
• Shelf life and storage
• Special vents as well as the high purity of lead and grid alloys ensure a low self-discharge rate and thus a long service life. Low storage temperatures improve the service life characteristics even further.
• Emergency Use
• The floating life or 20° life expectancy is 5 years for batteries up to 17 Ah and 10 years for batteries with capacities above 26 Ah.
• Cyclical use
• The number of charge/discharge cycles depends on the capacity taken from the battery (depending on the speed and depth of discharge), the operating temperature and the charging method.
• Design flexibility
• The batteries can be used in series and/or parallel to give you the choice of voltage and capacity.
• Compact design
• Power-Sonic batteries use state-of-the-art design, premium materials, and a carefully controlled plate manufacturing process to provide excellent per-cell performance.
• Design reliability
• State-of-the-art manufacturing and process control coupled with strict quality assurance procedures ensure consistent and reliable performance.
• Wide operating temperature range
• Charging: -15 to 50 °C
• Discharge: -20 to 60 °C
• Storage: -20° to +50°C (when fully charged)
