- Common button cells instead of a specialty battery: Four SR44 or LR44 cells in the adapter replace the hard-to-find 4SR44 / V28PX in your Pentax 67, Mamiya RZ67, Canon AE-1, AE-1 Program or A-1. You can also get the adapter here with four silver oxide cells (SR44) included.
- Silver oxide for steady voltage: With four SR44 cells, the voltage for metering and shutter speeds stays constant. Fitted with four LR44 cells, it’s the same adapter as the PX28 battery adapter for Canon AE-1, A-1.
- Flexible when you’re out shooting: In a pinch, LR44 alkaline batteries work too, and you’ll find those in almost any supermarket worldwide.

Description
Description
With this adapter, there’s no need to hunt down overpriced specialty batteries. It combines four standard button cells into a 6V stack that is mechanically identical to a V28PX or 4SR44. It sits in the battery compartment of your medium format or 35mm camera just like the original battery.
For cameras like the Pentax 67 or the Canon A series, we recommend the SR44 version, as silver oxide cells hold their voltage steady right to the end. LR44s are the backup you can pick up at the drugstore when you’re in a pinch.
Installation tip
Installation tip
On some cameras, the camera’s contact pin slips into the hole in the adapter’s eyelet instead of pressing against a battery contact. When that happens, the camera gets no power, and the adapter can snag as you take it out. If so, turn the cells inside the adapter around by 180° and insert the adapter rotated by 180° as well. The polarity stays the same, but the pin now lands directly on a battery contact.
Frequently asked questions
Frequently asked questions
Which cameras is this adapter sleeve for? Any camera body that takes a 6V V28PX, 4SR44, PX28 or 4LR44. We’ve tested it in the Pentax 67, Canon AE-1 and Mamiya RZ67.
LR44 or SR44: which should I choose? LR44s are alkaline and cheaper; SR44s are silver oxide and hold their voltage steady for longer. For the Pentax 67, with its power-hungry shutter, the silver oxide version with SR44s is worth it.
How many cells go in at a time? Four, and they come with the adapter version. You can restock from us with a refill pack of four SR44s, or pick them up anywhere batteries are sold.

Avoid. It's not the same as in the photo. See images and review.
Unusable. The adapter arrived is not the one in the photo. The metal contact has a much larger diameter (hole) and gets stuck with the tab in the camera housing (see images below), compromising the removal of the entire battery pack and risking damage to the camera body.
Absolutely useless. Not recommended.
Inutilizzabile. L'adattatore arrivato non è quello della foto. Il contatto metallico ha un diametro (buco) molto più grande (vedi foto allegate) e si incastra con la linguetta nell'alloggio della macchina compromettendo l'estrazione di tutto il blocco batteria e rischiando di danneggiare il corpo macchina.
Assolutamente inutile. Non consigliato.Reply from Ausgeknipst ·
Sorry, an adapter whose contact catches in the battery compartment and puts the camera at risk is not something you should have to work around. We want to find out what goes wrong in your camera. Write to info@ausgeknipst.de, and you can have your money back if you prefer.

Alu-Foil helped!!!
Had the same problem as Paolo Martino. The bottom hole of the adapter is way to big and the metal part of the adapter keeps the negative side of the batteries from touching its counterpart on the camera. (I tried the adapter with two Canon F1s and one Canon A-1, neither oft them had a pin long enough to touch the battery). So it didn't work. What helped was to put a tiny piece of Alufoil into the adapter first before filling in the batteries. Afterwards, the camera-pin touches the alu, which touches the batteries - and electicity flows!

Hi, thanks for describing exactly where the contact fails. On some cameras the contact pin slips into the opening of the eyelet instead of pressing on a cell. Instead of foil there is a simpler fix: turn both the cells and the adapter by 180°, so the pin lands directly on a battery contact with the same polarity. If your Canons still don't power up that way, write to info@ausgeknipst.de for a new adapter or a refund against return.
