2 pcs 1720mAh BLH-1 BLH1 Battery with Dual battery charger for EM1 MARK II EM1-2 EM1 Mark 2 EM1 Mark III EM1 Mark 3 EM1X E-M1X

I bought these for my Olympus EM1 MK2 as spare batteries are essential. However, the Olympus price tag of £65 each as opposed to £22.99 for two is no contest and a no brainer unless you have money to throw away. I have used compatible batteries before and they last just as long as the Olympus battery so why pay more. What I like about them is that unlike the Olympus charger which is charged by a mains socket these are charged by USB making it a lot more convenient. What I do not like is the warning on the screen ‘Olympus batt. Recommended’ every time you switch it on. Olympus should remove it or have the option available in the menu.

Works perfectly for a fraction of the cost of branded goods. I hope they last. Would be better if it used USBC rather than micro USB.

Great 3rd party batteries for my om em1 mkii.. Battery percentage shows on camera which some report it doesn't do.. Life of batteries around 500 shots whilst shooting a lot of macro with continual focus.. So great battery life

No issues with the camera complaining. They charge in about 3 hours though make sure the batteries are well seated. Battery life is much the same as the original. One thing I did notice is the original battery will not charge in this charger. I have not tried charging these in the Olympus charger but personally I prefer usb chargers especially with travelling.

Everything is good about this kit. Only downside is the battery life. They definitely do not hold their charge like the originals.....

Great service and carried as promised. Straight on the charger ready to use, no problems. 5* service.

Considerably less expensive than the Olympus OEM battery and works perfectly in my EM1-mk2, no ‘non standard battery’ warnings, all functions & battery life indicator as per original, and battery life seems similar to the original too. Twin charger works fine from a USB port. Only negative is that there are no plastic terminal covers so be careful storing the battery in your bag before use, I keep mine in small bubble wrap packets.

I had to give these batteries and the charger 5 stars for great value. Their capacity does seem a little smaller than the original batteries, and the numerical 0-100% battery level indicator doesn't work (though the battery graphic does). You also get the "Use Olympus Batteries" warning for a few seconds on wake-up. But they're reasonably quick to charge and drawing from USB is so useful. I'd sooner have 5 or 6 of these in my bag for the cost of 1 Olympus original. Shoot for days. A great option.
