    Default Battery charging



    Hi, new guy here. Great forum.

    Got a new Nexstar 130 SLT and I have a question and hope someone has the answer.

    If using rechargable batteries will the external charger charge the batteries in the telescope?

    I am sure someone here will have the answer.

    Thanks, D

    Welcome to the forum!!

    The answer is do NOT use rechargeable batteries, they do not supply enough power to the mount. It can cause all kinds of malfunctions. And fresh AA batteries don't last long either.

    To solve this, get an affordable 7Ah auto motive jump starter box, it will last you all night if all you're powering is the scope. Or spend a little more and get a 17Ah one and that will last several nights on one charge or power more devices for an evening.

    Hello and welcome to the forums, the best way to run these mounts is with the battery pack the others have discussed. But to answer your original question, no the mount will not charge batteries at all.

    Celestron mounts can be very finicky with power and when it gets low they tend to do strange things. The 7Ah or 17Ah battery packs will keep you operating for a night or two easily with no worries about power issues.

    Yep. I've got one of those, and a couple of smaller batteries. The one from Harbor Freight is probably the best value around.

    Or pick up one of these and strap it to the tripod/mount. You'll never know it's there. https://www.amazon.com/TalentCell-Re...gateway&sr=8-2

    Hi DK, and welcome here to the Forum!

    Great advice above! Celestron mounts are notorious for being finicky about the power supply. I strongly recommend using their AC wall adapter if convenient, or one of the high power rechargeables already mentioned.

    Good luck, and clear skies!

    For what it's worth, the equivalent Skywatcher mount seems to be more tolerant of rechargeable batteries. I very rarely have problems (though I do generally run off a 12V lead acid Leisure battery)

    The mount was not designed for rechargeable batteries so no it will not charge them , even using the very best ones on the slt mount as soon as the voltage drops below 10v I had problems, recharge batteries are 1.35 v when fully charged (and new) which is just ok but soon drop to 1.2 under load so using 8 you start of with 10.8 v which seems ok but soon drop to 9,6 which causes problems .
    Best as mentioned to use external battery pack , thats what I use

    I use NiMH rechargeable batteries. My experience with them is the same as Richard's.

    You can not simply substitute them for regular batteries. NiMH batteries are 1.2 vdc while regular batteries are 1.5vdc. This requires 10 NiMH batteries in series to produce 12 vdc while only 8 regular batteries are needed. If you simply substitute 8 NiMH batteries for 8 regular batteries you will be 2.4 vdc low. This is suffuciently low enough to cause problems with many telescope mounts. 8 fully charged NiMH batteries in series will be about 10.4 vdc which is at the lower acceptable voltage and will work for some mounts. However, they will quickly drop to 9.6 vdc which is insufficient for many astronomy related devices.

    I got around this issue by simply getting a 10 cell battery pack I found on EBay. The only reason I have for using NiMH batteries is when i need portability. My primary power source is a SkyWatcher Astronomy battery pack. An automotive jump start battery or astronomy battery pack are far more practical. Also charging 10 NiMH batteries is more of a hassle than charging one 12 vdc battery.
