| Camera | Battery | Notes |
|---|---|---|
| 645 Pro | 1× 4SR44, 4LR44 or 2CR1/3 (6V) Also at: Amazon | Spec table: “6V battery × 1 (4SR44 silver-oxide, 4LR44 alkaline-manganese or 2CR1/3 lithium).” The six AA cells often quoted for this camera belong to the Power Drive Grip WG401, not the body. |
| 645 Pro TL | 1× 4SR44, 4LR44 or 2CR1/3 (6V) Also at: Amazon | Spec table: “6V battery × 1 (4SR44, 4LR44 or 2CR1/3)” — same as the 645 PRO. The grip cells (WG401 six AA, WG402 its own 6V lithium) are accessories, not the body’s. |
| 645AF | 6× AA Also at: Amazon | Manual: “Use six SUM-3 (AA) alkaline or lithium” cells, in a detachable battery case. |
| 645AFD | 6× AA Also at: Amazon | Six AA alkaline or lithium cells. |
| 645AFD II | 6× AA Also at: Amazon | Six AA alkaline or lithium cells. The camera will not operate without batteries. |
| 645AFD III | 6× AA Also at: Amazon | Six AA alkaline or lithium cells, and the camera will not operate without them. The film magazine carries its own CR2032 for its LCD. |
| 645E | 1× 4LR44, 4SR44 or 2CR1/3 (6V) Also at: Amazon | Manual: 6V — alkaline 4LR44, silver-oxide 4SR44 or lithium 2CR1/3. Electronically timed, so a flat cell means no exposures; The lithium is the one for cold weather. |
| C22 | None | No battery: the TLR's Seikosha shutters are in the lenses, and the manual mentions no battery anywhere. |
| C220 Professional | None | No battery in the body: leaf shutters sit in the lenses and there is no built-in meter. A metered prism or Porrofinder, if fitted, carries its own cell — that is the battery people are usually hunting for. |
| C220f | None | No battery: the Seiko shutters are in the lenses, and the manual mentions no battery anywhere. |
| C3 | None | No battery: the TLR's Seikosha shutters are in the lenses, and the manual mentions no battery anywhere. |
| C33 | None | No battery: the TLR's Seikosha shutters are in the lenses, and the manual mentions no battery anywhere. |
| C330 | None | No battery in the body: leaf shutters sit in the lenses and there is no built-in meter. A metered prism or Porrofinder, if fitted, carries its own cell. |
| C330s | None | No battery in the body: leaf shutters sit in the lenses and there is no built-in meter. A metered prism or Porrofinder, if fitted, carries its own cell. |
| M645 | 1× 4SR44 or 4LR44 (6V) Also at: Amazon | Manual: one 6V silver-oxide 4SR44 (Eveready 544, UCAR 544, Mallory PX28 or equivalent) or alkaline 4LR44. |
| M645 1000S | 1× 4SR44 or 4LR44 (6V) Also at: Amazon | Same 6V pack as the M645 — 4SR44 or 4LR44 — confirmed against the 1000S manual’s own battery pages. |
| M645 Super | 1× 4SR44 or 4LR44 (6V) Also at: Amazon | Manual: “one 6V silver-oxide battery (4SR44) or 6V alkaline-manganese battery (4LR44).” |
| M645J | 1× 4SR44 (6V silver oxide) Also at: Amazon | One 6V silver-oxide cell — Eveready or UCAR 544, or Mallory PX28, the size now sold as 4SR44 — for the electronic focal-plane shutter. |
| Mamiya 6 | 2× SR44 or LR44 Also at: Amazon | Two SR44 silver-oxide or LR44 alkaline cells. The camera will not function without them. |
| Mamiya 6 MF | 2× SR44 or LR44 Also at: Amazon | Two SR44 silver-oxide or LR44 alkaline cells — the same as the Mamiya 6. The camera will not function without them. |

| Mamiya 7 II | 1× 4SR44 / 4LR44, or 1× 2CR1/3 (6V) Also at: Amazon | One 6V cell: a 4SR44 silver-oxide, a 4LR44 alkaline or a 2CR1/3 lithium. The camera will not function without a battery. A 4LR44 is a single 6V cell — not an LR44, which is a 1.5V button. |
| Press Standard | None | No battery: the lenses carry Seikosha leaf shutters, and the manual mentions no battery anywhere. |
| Press Super 23 | None | No battery: the lenses carry Seikosha leaf shutters, and the manual mentions no battery anywhere. |
| RB67 Pro-S | None | No battery anywhere in the body: the shutter is in the lens, wind and mirror are mechanical, and there is no built-in meter. It works exactly as well with no power source at all. A metered prism finder, if fitted, carries its own cell. |
| RB67 Pro-SD | None | No battery: the Seiko leaf shutters are in the lenses, and the shutter and mirror are cocked with a lever on the body. |
| RZ67 | 1× 4SR44 or 4LR44 (6V) Also at: Amazon | Manual: one 6V silver-oxide 4SR44 or alkaline 4LR44. Electronically timed, but the spec sheet also lists a mechanical 1/400 sec. Usable without a battery — an emergency speed, not a way to run the camera. |
| RZ67 Pro II | 1× 4LR44 / 4SR44 (6V) Also at: Amazon | One 6V 4LR44 alkaline or 4SR44 silver-oxide cell. If it dies, lining the release-button collar up with the orange dot still fires the shutter at about 1/400 sec. A 4LR44 is a single 6V cell — not an LR44, which is a 1.5V button. |
| RZ67 Pro IID | 1× 4SR44 / 4LR44, or 1× 2CR1/3 (6V) Also at: Amazon | One 6V cell — 4SR44, 4LR44 or, unlike the Pro II, a 2CR1/3 lithium. Without a battery the emergency setting still fires the shutter at about 1/400 sec. A 4LR44 is a single 6V cell — not an LR44, which is a 1.5V button. |
| Universal | None | No battery: the lenses carry Seiko leaf shutters, and the manual mentions no battery anywhere. |

Digital
Mamiya’s digital bodies are a mixed bag. The 645DF runs on six AA cells1, and the 645DF+ adds Mamiya’s rechargeable lithium-ion pack as an alternative to the AA holder.2 The integrated Mamiya ZD uses its own BA701 lithium-ion battery.3

| 645DF | 6× AA Also at: Amazon | — | Six AA alkaline or lithium cells (NiMH or NiCd work if the battery-type setting matches). Without batteries the shutter can't be released. |
| 645DF+ | Mamiya Li-ion pack, or 6× AA Also at: Amazon | — | Takes Mamiya's rechargeable lithium-ion pack, which slides into the battery compartment in place of the AA holder, or six AA cells. |
| ZD | BA701 Also at: Amazon | DE-975A In box | Mamiya's BA701 lithium-ion battery with the DE-975A charger. |
Things worth knowing
Several of these cameras run on 6V cells. The most common model numbers you’ll see them listed under are 4SR44 or 4LR44.
The 4SR44 is a silver-oxide cell, while the 4LR44 is alkaline. Both work in the bodies listed above, but Mamiya’s own M645 manual makes this distinction:
This camera is designed for use with either silver oxide or alkaline batteries. Although both types offer adequate performance, silver oxide batteries last much longer.4
Mamiya’s M645 manual also lists the 4SR44 under other names: Eveready 544, UCAR 544 or Mallory PX28.5
They’re still in production (they’re used for other devices, too) and easy to find online, even if they’re not sitting on your local store’s battery stand.
Note that you will find listings online for 4SR44 and 4LR44 as well as SR44 and LR44. You want the one that starts with a “4”; the versions without that leading 4 are much smaller batteries that won’t work in this camera. The correct batteries are shaped a bit like a squat AA battery, not a button battery. And the “S” versions are silver oxide; the “L” are alkaline. Both will work in the camera, but Mamiya says the silver-oxide versions last much longer.
RB67 vs. RZ67: which one needs a battery
The RB67 and the RZ67 look very similar from the outside. But the RB67 is entirely mechanical and takes no battery at all.6
The RB67 Pro-S and Pro-SD have no battery anywhere in the body: the shutter is in the lens, the wind and mirror are mechanical, and there is no built-in meter.7 A metered prism finder, if one is fitted as an optional extra, carries its own cell.8
The RZ67 has an electronically timed shutter and stops working without one. It takes a single 6V cell — a 4SR44 silver-oxide or 4LR44 alkaline.9 The RZ67 Pro II takes the same cells, and the Pro IID adds a 2CR1/3 lithium as a third option.10
There is one exception worth knowing if you have an RZ67, and it applies to the Pro II and Pro IID too. If you turn the collar around the shutter release to the orange dot, the shutter will fire mechanically at roughly 1/400 second, with no battery at all.11 It’s meant as an emergency backup setting, not a way to run the camera — every other speed still needs power — but it’s also a tell: if your camera only fires at 1/400, it probably means that the battery is flat rather than the shutter is broken.
The 645AF runs on AAs, the earlier 645s don’t
The 645AF takes six AA cells, loaded into a removable holder that slots into the grip12 — easy to find pretty much anywhere in the world you’re traveling with one. The 645 Pro is not an AA camera: like the M645 and M645 Super, it runs on a single 6V cell in the body, the 4SR44 or 4LR44.13
The later 645AFD, 645AFD II and 645AFD III take the same six AAs, and none of them will operate without batteries.14 The AFD III’s film magazine also carries a small CR2032 of its own for its display.15
The 6 and 7 rangefinders need power to shoot
The Mamiya 6 and 6 MF take two SR44 or LR44 button cells16, and the Mamiya 7 and 7 II a single 6V cell — a 4SR44, a 4LR44 or a 2CR1/3 lithium.17 Mamiya says none of them will function without a battery18, so a spare is worth carrying.
The TLRs and press cameras take no battery
The C3, C22, C33 and C220f twin-lens reflexes, the Press Standard and Super 23, and the Universal have their shutters in the lenses, and their manuals mention no battery anywhere.19
