The Olympus OM-1 mirrorless camera makes reasonably good use of its battery life, but mirrorless cameras do tend to burn through battery life quite rapidly. So you’re going to have to charge that battery sooner rather than later. Or maybe you need to replace the battery or want the extra convenience of having a spare so you can keep shooting while the other charges.

Olympus is now OM System

In 2020-21, the photography business of iconic camera brand Olympus was spun off and sold. The core remaining Olympus brand is focusing on medical and scientific products. The camera and photography side was then rebranded as OM System, with the first cameras and lenses under that brand coming out at the end of 2021.

Here’s a rundown on which batteries the OM-1 uses as well as options for charging it.

Batteries for the OM System OM-1

The Olympus OM-1 camera uses battery model BLX-1. Whether you’re looking for an official OM System battery or an aftermarket alternative, they’ll be listed under that model number.

Official OM System BLX-1 Battery

The BLX-1 is a 7.2V lithium-ion rechargeable battery rated for 2280mAh.

These are the batteries OM System guarantees to work with the camera, so they’re the safest option.

Aftermarket Alternatives to the BLX-1 Battery

OM System recommends that you only use their official batteries. But it also means you pay the manufacturer’s premium prices. And, well, they’re not cheap.

In practice, you can often find good-quality aftermarket versions that can work well and be much cheaper.

They appear under a bunch of different brand names, and it can be a little like the Wild West because quality control can vary quite drastically. But I’ve had good experiences over the years with aftermarket battery brands like Wasabi Power, Kastar, Powerextra, and Watson, and Power2000.

How to Charge the OM-1 Battery

There are two main ways to charge the OM-1 battery: in the camera or in an external charger.

Option 1: Charge the Battery in the Camera

This is the method that’s available to charge the camera battery right out of the box. The OM-1 comes with the USB cable you need as well as an AC charger.

As always, they recommend in the manual that you stick with the original (and official) wall charger and USB-C cable. But I’ve been using standard USB-C cables and USB charging hubs without any problem at all (but do make sure that the USB-C cables are compatible with PD charging). But if you want to replace the original, official wall charger, it’s model F-7AC.

When you plug the camera in using the USB-C cable, you should see a small orange light come on the back of the camera, down at the bottom right next to the trash button.

OM System says that fully charging the battery from empty, with the camera turned off, takes around 2 hours 30 minutes. I haven’t timed it specifically, but that sounds about right in my experience.

Option 2: Use an External Charger

The camera doesn’t come with an external charger, but one is available as an optional extra accessory. There’s an official OM System one available as well as aftermarket alternatives.

Official External Charger

The official charger is model BCX-1, and it’s a dual charger (the SBCX-1 is the same charger packaged with a spare battery).

Aftermarket External Chargers

As with the batteries, there are also good aftermarket versions available produced by third-party manufacturers. Not only are they often significantly cheaper, but you can also get them in different configurations.
