Description

The PowerTank Lithium keeps the charge going for the astronomer on the go. The Lithium-Iron 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 Iron and 6-9 months for a Sealed Lead-Acid battery.

- The battery performance of the PowerTank Lithium phosphate degrades at a much slower pace than other chemistries.

- The LiFePO4 can be charged and discharged 2000 times compared to only 500 for a Lithium Iron battery and 300 for sealed lead-acid designs.

- The batteries will last as long as the telescope you use it with!

- The LiFePO4 uses phosphates instead of environmentally hazardous elements like cobalt or lead commonly found in other rechargeable batteries.

- Can withstand higher temperatures than lithium-iron designs and will not be a fire danger if accidentally punctured.

This combined with its rugged design make it the perfect outdoor power supply.

Keep your telescopes, smartphones, tablets, GPS systems, cameras and other USB-powered devices as active as you are with PowerTank Lithium—the ideal outdoor portable-charging solution for your electronic gear.

FAQ

Q:

PowerTank Lithium – Auto Shutoff Feature

A:

PowerTank Lithium batteries come with a safety feature that prevents them from slowly discharging if they are left unattended for long periods of time.

Q:

My Celestron PowerTank is taking longer to charge and to show a fully charged light. Why?

A:

PowerTanks use a lead-acid battery technology. These batteries start out new at 100% capacity in amp-hours. PowerTanks come in 7 amp-hour and 17 amp-hour capacities.
