A - Integrated flame protection Total Safety B - Battery charge level indicator on the Freedom Plus and Freedom ranges: instant checkin of the state of charge. Practical C- Ca/Ca Technology : heat sealed cover Absolutely maintenance free very low self-discharge rate Increased storage time D - Container made from reinforced polyproplene Resistance to shocks and light in weight E - Plates are solidly fixqed F - Grids in cold-drawn micro-structured alloy (high resistance to corrosion) increased longevity G - Antimony free plates (addition of water unnecessary) Absolutely maintenance free H - Plate seperators / jacked : avoid short-circuius  increased longevity I - The plased are mechanically welded and connected by central lugs Resistance to shocks J - Gas / liquid seperator (wich sends any liquid in the gas back into the reservoir) Safety
