The X is probably from before the time of the X and at that time I don't know whether even the non-rechargeable AA lithium batteries were available. What experiences have others had using AA size rechargeable lithium batteries on old flash units? Jan 21, 2. Messages: 4, Precharged rechargeable batteries will discharge in storage over time, self discharging design faster than non self discharging design. Time frame from manufacturing charge until you received them will likely remain unknown.
Rechargeable batteries usually have a lower voltage than their alkaline counterparts at full charge. NiCad's were much lower and cameras have a switch for Nicad or LR6. The most overlooked feature of rechargeable batteries is their current rating usually stated in millamp hours. This is the amount of current that the battery can supply in one hour.

Jan 22, 4. Is it lithium? I went over the Survival Frogs website and can not confirm what type of batteries they are.
I don't think the batteries would damage the flash. Jan 23, 5. Discussion in ' Accessories ' started by kiniboat , Dec 5, Can a flash unit from a film set up be used with a digital camera such as a Cannon Rebel XT. Thank you for any information. This is an old early 80s flash unit. As such, it predates the introduction of advances such as TTL flash metering and red-eye reduction.
Still, you should be able to use the automatic mode on this flash; this means that the flash duration is set by the metering cell on the flash itself. And of course, this flash is perfectly usable if you do all the calculations yourself. There's quite a bit to be learned about how to use flash, and a quick summary doesn't cut it.
The Minolta Auto X is an excellent flash. There's a lot you can do with it. One caveat is that the flash has one extra pin on the hotshoe that was for a relatively unimportant feature for Minolta cameras. This shot of the rear of the flash shows its settings, including two auto settings as opposed to three in the X and a low and high manual setting.
The flash is basically the precursor to the PX, introduced with the X-Series of accessories. This makes it exceptionally good value for someone seeking a basic flash unit for use with any camera. Based on the previous generation Auto 32 Electroflash the X had a high guide number of 32 in metres, and incorporated a bounce but not swivel head.
The big difference with the X is that it lacks the thyristor circuitry that saves the unused charge in the capacitor when the flash is used at less than full power. This means that it is unsuitable for continuous Auto Winder use, and will use batteries faster than the X and X.
However, for infrequent users of flash it would make a very good cost-effective choice giving the advantages of bounce flash for a very low price. The PX came with a soft leatherette case, and a clip on wide angle adapter that took its standard coverage from 35mm to 28mm at the cost of one stop of power.
Additionally, an optional filter set was available for special effects. The most compact of all of the Minolta auto flash units, the X had a guide number of 18 in metres, with two auto settings plus manual.
It was a basic unit with no bounce or swivel capability, and did not include thyristor circuitry. The switch to select the mode manual or one of two auto settings is on the side of the flash, and the rear of the flash has a simple flash calculator for use in all modes. The Power Grip 1 is an external power pack designed to supplement the batteries of the X flash for use in motorised mode, or for faster recycle times in general use. It uses a Nicad battery pack which is no longer available, and like all Nicad systems, has a limited life.
Given there is no option for the use of AA batteries like the later Power Grip II it is difficult to locate a set still in operational condition. Additionally, for those of a handy nature, the original NiCad battery pack can be dismantled and new cells installed. The Power Grip 1 takes the flash off camera, but lacks the bounce and swivel features and shutter release button of the later Power Grip II. However, with a bounce and swivel flash such as the X the Power Grip 1 may be a cost effective and compact method of getting your flash off camera.
With thanks to Joerg Tillmann for additional information.
