Battery Pb 12V 7.2Ah F2 (operating temperature from -40ﾟC to +65°C) CRYSTAL AMPOWR

The next evolution in battery technology
Compared to mainstream rechargeable industrial batteries, a Crystal Batteries (Lead Crystal) battery always perform better due to their unique and patented characteristics.

The technology
The patented Crystal Batteries (Lead Crystal) technology uses a specially advanced formula, a new type of composite SiO2 electrolyte developed to completely replace traditional sulphuric acid solution. When charged/discharged the liquid electrolyte transforms into a crystallized state leaving hardly any free liquid electrolyte in the battery, effectively resulting in a dry cell.

Advantages
Compared to mainstream rechargeable industrial batteries like lead acid, lead gel and AGM batteries, a Lead Crystal battery perform as follows:

Crystal Batteries™ batteries can be charged faster (Very low internal resistance)
Crystal Batteries™ batteries can be discharged deeper (even to 0 Volts!)
Crystal Batteries™ batteries have an operating temperature from -40 to +65 Celsius
Crystal Batteries™ batteries can be charged below 0 degrees Celsius
Crystal Batteries™ batteries can be cycled more often (620 @ 100% DOD, 2200 @ 60%, 6000+ @ 20%)
Crystal Batteries™ batteries have very low gassing (IEC 60896-21/11 – less than 2% of normal AGM)
Crystal Batteries™ batteries can be used in a partial state of charge
Crystal Batteries™ batteries can be stored for 2 years without top-up charging
Crystal Batteries™ batteries hold no cadmium, no antimony and < 5% sulphuric acid 
Crystal Batteries™ batteries require no special ventilation or cooling
