How long do i charge a sunpak nc 510 rechargeable using a QBC-5 CHARGER

There is not a fuse but there are batteries. Even rechargeable batteries go bad.

Hi,
Sunpak uses different power sources on their high-power handle mount (a.k.a. hammerhead) flash guns. The most common is the battery basket that holds 4 or 6 AA or C batteries depending on the type of the unit. One can insert Nickel-Cadmium or Nickel-Metal-Hydride rechargeable batteries instead of the primary cells, this way reducing the "consumables" costs at the expense of the smaller number of flashes per battery set. (Actually, NiCd or NiMH cells would probably give smaller number of flashes compared with the alkaline cells, but the recycle time between the flashes can be shorter. The reason is that at charging the flash capacitor inside the flash current counts more than voltage. Sunpak sells Ni-Cd battery packs named CL-2 for their flashes that utilize 6 AA-cells, and CL-3 for their 622 series (4 C-cells). The charger for these is the QBC-5. It recharges the exhausted batteries in 3 hours. As a solution assuring the shortest duration between flashes Sunpak offered the Powerpak, a shoulder holster that held a dry (non-rechargeable) battery of 510V, it charged the flash capacitor directly, omitting the transistor inverter in the flash body. As such battery became obsolete, the Poverpak has been superseded with the NC510 and later the TR-II PAK, which utilizes 10 Ni-Cd rechargeable batteries as a power source, and a powerful (more capable than the one in the flash) transistor inverter. NC510 and TR-II PAK use the same connection to the flash and the same outlook as the original Powerpak but, being rechargeable, are more economical. QBC-5 also serves a charger for the NC510 and TR-II PAK. You may ask, how the same charger can be used for 4, 6 and 10 cell NiCd packs. Well, the charger is specially designed for that, although charging time differs at the different battery packs. The NC510 and the TR-II PAK needs 10 hours to be recharged, when exhausted. The best way to avoid damages (overcharging degrades NiCd and NiMH cells) is to check temperature of the batteries. Charging must be cut off if the battery becomes hotter than 45 ?C (115 ?F). If after 10 hours of charge the NC510 does not power (the otherwise working) flash, then it must be serviced. Replacing the batteries is an easy job that can be done at home, with some soldering skills; NiMH cells with solder tabs are available at many web-based supplyers. Don't solder the cells directly, heat damages them. Avoid touching parts inside, when the pack is turned on: electrocuting is fully possible. Better find a professional, if you are not familiar with the electronics.

There are two possibilities. First, rechargeable batteries do not last forever. Take out your rechargeable batteries and replace them with non-rechargeable ones for test purposes. If your camera works ok, it may be that the camera's charger circuit has gone bad. Try charging your batteries on an external charger. If they charge, it is your camera's charger, if they do not hold a charge, it is probably time for new rechargeable batteries.

Rechargeable batteries have a limited life determined by how many times they've been discharged & recharged and how old they are. On the charger there are lights and a chart to let you know what's going on with your battery. If it indicated the battery is defective, the charger won't even try to charge the battery and it needs to be replaced. If it goes through a recharge cycle and then lasts for a couple minutes or not at all the battery is used up and needs to be replaced. If none of the lights on your charger are working the problem may be the charger. The only way to test that is to have someone else with an LXT kit try to recharge your battery.

Yes, assuming you're using rechargeable batteries. If you're using rechargeable AA batteries, they can be recharged using any standard AA charger. If you're using the Kodak Rechargeable Battery Pack, it can be recharged using any of several Kodak chargers.

Sunpak TR-Pak II a NiCad flash battery pack with charger and Quantam battery both has cords for 622.
Personally I have taken out wire pair from removable battery pack of 622 and connected to 4 cells of Nicd type D battery pack made at home.(I placed that in my belt bag).
want more details ,feel free to email at [email protected]

I had the same problem - 10-11 secs on 240VAC. My solution was to get the Quantum Turbo SC for $450. It yields ~3sec recycle times. This pack for $150 should play nicely as well: http://www.adorama.com/JTMBPN.html?searchinfo=jtl+lancer+battery+pck It was out of stock at the time. The Sunpak TR2000 is $250, but it's Ni-Cd while the others are NiMH. There are other HV packs capable of powering the 622 w/ the fitting cable like Lumedyne IIRC. The AD-26 is still useful for non-action photography. The fastest time I saw posted is 1.5 secs, but it's a DIY job (search 'sunpak 622' on flickr). HTH,

Your LXT350 is equipped for using an optional rechargeable NiMH battery pack which can be recharged by inserting the AC adapter into the radio charge jack, or with the optional desktop charger.

I would make sure the radio is off, then insert the charger. Charge only for the prescribed time (no more/no less) and remove from the charger.

Charge time is initially 24 hours. Charge time is about 12 hours thereafter. For maximum battery life, it is recommend charging the battery pack when the low battery icon comes on. Remove the radios from the charger when the charge time expires.
