Lightweight and tripod-mountable, it offers superior safety, a 5-year lifespan, and a 2-year warranty, making it the ultimate power companion for serious amateur astronomers. ## Description Keep your telescopes, smartphones, tablets, GPS systems, cameras and other USB-powered devices charged and ready with PowerTank Lithium LT—the ideal outdoor portable-charging solution. Celestron specially designed this product with the needs of amateur astronomers in mind; it’s packed with useful features. First, you’ll find a 12V connection for your Celestron telescope—no cigarette lighter port needed. Once your telescope is connected, attach the battery securely to one of the tripod legs with the included Velcro straps so it is safely out of the way. One USB port keeps your other devices charged, and can be used simultaneously with the telescope charger. When you’re not observing, keep this battery charged and at the ready for unexpected emergencies. PowerTank Lithium LT’s unique Nickel Manganese Cobalt Oxide chemistry which delivers a steady charge over long periods and requires less maintenance than a traditional sealed lead-acid battery. It will last you many times longer thanks to its un-recharged shelf life of 10 years and 2000 charge cycle lifespan. But most importantly, the PowerTank Lithium LT can withstand higher temperatures than standard lithium cobalt batteries and will not be a fire danger if accidentally punctured. All this combined with its rugged design make PowerTank Lithium LT the perfect outdoor power supply. Review: Works as expected - Steady source of power for my Vespera Pro smart telescope. The outside temperature was around 2 or 5 Celsius. The powertank came in super handy to keep my pro charged up all night as planned. Small, deceptively light and works as expected. Review: Much more convenient and powerful than the lead-acid battery Power Tank. - I bought this battery to replace the Celestron Power Tank that I had for over 10 years. That model used a lead acid battery, and it had two USB ports, along with a very bright LED flashlight. Unfortunately, it quit holding a charge. I decided to buy this model because it is smaller, more convenient, and it holds a charge far longer than the previous model. In a recent trip to Joshua Tree National Park to observe the Milky Way, I used this Power Tank to power my telescope, and it performed flawlessly. In fact, I had forgotten to charge it the first night, and it still had plenty of juice leftover for the second night. I highly recommend it. I hope this review helps. ## Features - PORTABLE POWER MADE FOR ASTRONOMERS: The perfect solution for most computerized telescopes, PowerTank Lithium LT features a regulated 12V connection, 8 hours of battery life, a USB port, and more. Mounts directly to the tripod leg. - SMALLER, LIGHTER, SAFER: Unique Lithium Nickel Manganese Cobalt Oxide chemistry delivers a steady charge over long periods and requires less maintenance than a traditional sealed lead-acid battery. - 5 YEARS OF DEPENDABLE PERFORMANCE: Unlike other batteries with limited lifespans, PowerTank Lithium LT will be your companion for 5 full years of astronomy adventures. - WORKS WITH A VARIETY OF DEVICES: 12V connection works with all current Celestron computerized telescopes.

The outside temperature was around 2 or 5 Celsius. The powertank came in super handy to keep my pro charged up all night as planned. Small, deceptively light and works as expected. ### ⭐⭐⭐⭐⭐ Much more convenient and powerful than the lead-acid battery Power Tank. *by I***R on August 7, 2025* I bought this battery to replace the Celestron Power Tank that I had for over 10 years. That model used a lead acid battery, and it had two USB ports, along with a very bright LED flashlight. Unfortunately, it quit holding a charge. I decided to buy this model because it is smaller, more convenient, and it holds a charge far longer than the previous model.

In fact, I had forgotten to charge it the first night, and it still had plenty of juice leftover for the second night. I highly recommend it. I hope this review helps. ### ⭐⭐⭐⭐⭐ Excellent Power Source *by L***. on January 1, 2021* This proved to be an excellent power source for my Celestron NexStar 8SE. My bulky old power tank (the one that looked like a small suitcase) was no longer holding a charge, so I decided to just go with the 8 AA batteries. Had problems getting the scope aligned, tracking, slewing etc. Apparently it didn't take long for the batteries to lose enough power to start causing problems. Decided to give this thing a try. What a difference! My scope is now operating perfectly. I haven't had this thing long enough to tell you how long it lasts, but I have used it for several nights now without recharging. (Admittedly, I don't stay out more than an hour or so in the winter.) A nice feature: It has indicator lights to let you know the level of charge. In order to avoid cord wrap issues, I velcroed it to the top of the battery compartment. This works great MOST of the time. But in this position, it is thick enough that it can interfere with the scope slewing to an object high in the sky. (Easily remedied by temporarily removing it to the tray below. Just be careful of cord wrap.) Anyway... I am very happy with this product so far, and greatly relieved that my expensive scope is now operating as it should! ## Frequently Bought Together - Celestron 18763 PowerTank Lithium LT Telescope Battery Power Pack – Rechargeable Portable 12V Power Supply for Computerised Telescopes with 8 Hour Capacity / 73.3 Wh and 1 USB Port, Black - Celestron 93973 Skyportal WiFi Module, Black - Celestron 94303 1.25 inch Eyepiece & Filter Kit - Includes 14 Pieces in Metal Foam-Lined Carry Case, Silver --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/181810228-celestron-18763-powertank-lithium-lt-telescope-battery-power-pack-rechargeable](https://www.desertcart.hr/products/181810228-celestron-18763-powertank-lithium-lt-telescope-battery-power-pack-rechargeable) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-19*
