Product Details

  • The Celestron PowerTank Lithium drastically exceeds the parameters of both standard Lithium-Ion batteries that predate it and Sealed Lead-Acid Batteries. And it's not just more effective - though it certainly is that. It's also safer, lighter, and more convenient!

    Celestron PowerTank Lithium Features

    It's more compact, lightweight design makes it perfect for the astronomer on the go who needs to power their computerized scope and mount far away from home, and it's dependable output and incredible lifespan make it ideal for anyone. 

    The Lithium PowerTank has an un-recharged shelf life of 10 years, which is almost three times the 3 years boasted by a standard Lithium-Ion battery and is a full ten times as long as a Sealed Lead-Acid battery. And it'll last almost as long even if you are recharging frequently; it's able to be fully charged and discharged two thousand times before issues occur, compared to the Lithium Ion's five hundred, and Sealed Lead-Acid's mere 300. You won't find a longer-lasting, more dependable battery for your USB powered devices to run on!   

    This battery is safe to use! It can handle higher temperatures than a comparable Lithium-Ion design, and unlike its competitors is not a fire hazard if pierced! This makes it safer to take this battery with you out into the world, like on a hike.

    For related reasons, it's also a more environmentally friendly option than most other batteries. It uses phosphates instead of environmentally hazardous elements, like cobalt or lead, commonly found in other rechargeable batteries.

    Power tank battery

    I didn’t know that the battery is only for using the telescope with a computer You don’t need it to see the stars

    Good product !

    I bought this item for the Nexstar 8se telescope. My telescope mount moved faster and stronger than a 1.5v alkaline battery. This product can charge the cell phone, is easy to carry and light. Good product.

    I was astonished by the operation of this powerful battery for operating my telescopes...put under telescopes on eyepiece carriage avoiding twisting wires and lines... I was so impressed with this product I purchased its bigger brother which is so popular it is on back order...the guys on OPT chat were fantastic in assisting me with this and all purchases...I could not be happier with my experience with OPTCorp.. I have no relationship with OPT and I receive no special discount/benefit for writing the abode.. Willis Sutherland Sarasota
