Quote:I have a Celestron Power Tank 7A that I recently had to change the battery on. They are fussy if you don't keep em charged. Suggest a Battery tender Junior if you go that route.
Quote:Look for a powerpack that has "smart charging" circuitry. One that can be left plugged in indefinitely ... avoiding over-charging problems ... and one that can be re-charged at any point during the discharge cycle ... avoiding the "battery memory effect" problem. Many units don't have this feature and the internal battery can fail prematurely from overcharging or/or charging the battery when it's only partially discharged. I bought a Duracell 300 Powerpack with "smart-charge" and it runs all my portable scopes (including the ETX-125) ... doing "double duty" around the house and on the road. I've had it for over 3 years and it still charges back up to 100%.
