Inside the Celestron PowerTank Lithium and Lithium Pro portable battery power supplies lies Lithium Iron Phosphate (LiFePO4) technology.

The battery chemistry boasts an un-recharged shelf life of 10 years – compared to 3 years for lithium-iron and 6-9 months for a sealed lead-acid battery. LiFePO4 batteries can be charged and discharged 2000 times compared to only 500 for lithium iron batteries and only 300 for sealed lead-acid designs. This means that these LiFePO4 batteries will last as long as the telescope you use it with!

LiFePO4 uses phosphates instead of environmentally hazardous elements like cobalt or lead commonly found in other rechargeable batteries. Furthermore, these batteries can withstand higher temperatures than lithium-iron designs, and will not be a fire danger if a cell is accidentally punctured.
