The 'Online' range of sealed lead acid batteries are maintenance free, valve regulated and leak proof ideally suited to all 'standby applications'
There will be no loss in power output over the battery life.
Low self-discharge of about 2-3% per month compared with 20-30% for more common battery systems.
Quality construction with no compromise on materials to ensure a long service life.
Low internal resistance means a high discharge rate.
Wide operating temperature range operating between -15° C to +50 ° C when fully charged.
