Celestron Powertank Lithium 2458455 while at the same timeThe new PowerTank Lithium keeps the charge going for the astronomer on the go. The Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries. The LiFePO4 has an un recharged shelf life of 10 years compared to 3 years for the Lithium Ion and 6 9 months for a Sealed Lead Acid battery. The battery performance of the PowerTank Lithium degrades at a much slower pace than other chemistries. The LiFePO4 can be
