How long should I charge my Celestron PowerTank 17 for the first time and after that?

[Brooklyn]

To get the most out of your Celestron 18777 PowerTank 17 12V Power Supply, initial charging is key. When you first get your PowerTank or after extended storage, charge it for 15 to 20 hours. For subsequent charges, you'll typically need to charge for 10 to 12 hours. However, if you've used the PowerTank until the yellow LED indicates low battery, the recharge time could extend up to 20 hours. Always follow these guidelines to ensure your PowerTank remains in top condition and provides reliable power for your astronomical adventures.
