Bought the 7AH version a couple of years ago. The floodlight never worked due to a broken switch, but I didn't bother to ship it back since I only wanted the battery to power my mount. (First thumb down if you actually want a working flood.) I probably got 20-30 observing sessions out of it with no apparent problem. It will certainly run the drive for several hours if you don't also have your CCD or dew heater plugged in. Unfortunately, it's been in the closet for over a year and will no longer charge. Could be the typical problem of a cheap battery not being cycled for an extended period of time. Or could be the fact that the charging unit is putting out 2.5A at 22V when it's rated for 500ma/15V. Lol... (Second thumb down.)

I use this with my NexStar 6SE. I don't know how one can use the telescope without this. Simply 'a must'.

I've received two Celestron Power Tanks from Amazon so far and neither would accept a full charge after 23- and 24-hours, respectively. I notified Celestron Customer Support of the problem with the first Power Tank and they said it was defective as is should have charged within 12 hours. Amazon.com was very prompt about sending me shipping instructions and a replacement. However, the second battery was also defective. I contacted Celestron Customer Support again and they apparently passed the problem on to Amazon.com as I soon received an email from them saying they would send me another replacement however I would have to pay the postage to return the second defective one. Save yourself time, aggravation and expense - don't order a Celestron Power Tank.
