BM Premium2 Pack of Fully Decoded BL-H1 Batteries and Dual Bay Charger Kit for Olympus OM-D E-M1 Mark II, E-M1 Mark III, E-M1X, BCH-1, HLD-9 Cameras

Reliable charger

I have very limited experience with these batteries and charger so far but at the moment I can say I am very happy with them. I have used each battery and gone through a couple discharge / recharge cycles. They indeed do report their percentage of charge to the camera (I have an OMD EM1 Mk II with firmware 3.5) and seem to last just as long as the original Olympus battery. The charger works ok and has them recharged in a few hours. I have not done any testing to determine more exact numbers of any of this but again, so far I am very happy. For the price of less than one Olympus battery you cant go wrong.

Traveling in Scotland with these right now. They lag just slightly shorter than the Olympus battery, but it’s okay, I bought 3 of these. Hit the isle of May and took 2400 photos on 2 batteries total. Not so bad.Much of that was high speed, C-AF.Good value. Glad I bought them. Send better than the kastar ones I’ve had. Just is still out on longevity.

I ordered 3 of these batteries. 2 work just fine. The 3rd will only charge to about 25-30 %. I sent BM an email hoping for a replacement and their reply was that "It was normal for them not to charge fully and will take more cycles to accept more charge". From my experience that isn't the case. I've purchased many batteries for many cameras for both professional and personal use. This is the first time I've heard of batteries gaining 70% more capacity with continued use. Plan on returning through Amazon.

The quality of the charger and the batteries is very good. The batteries charge a little slow; I would like to see the wattage upped a little to cut down on the time it takes to charge the batteries particularly when you charge them both at the same time. I have not yet had enough time to determine how long they last in my camera after being fully charged.

BATTERY COMMUNICATION ERROR appears on screen only when these batteries are installed in the camera. No good.Charger is also slow, but that is to be expected since it is mini usb powered.

Nice to have some extra batteries for my E-M1 camera. Virtually identical to the OEM battery in form and function.

Great batteries

This set wqs a great addition to my camera set up at a fraction of the original equipment price. The batteries last about 300-400 shots but having two on hand works great for travel. Charges nicely and they charge to 100% without fail. Been using these for 2 months now and feel confident they will last a while.

Super deal with the included double charger. Works with the battery indicator on my OM-D E-m1 Mark II. Battery life seems identical to the Olympus branded battery.

les batteries sembles de bonne qualité a`voir à l'usage

Decodes batteries, run welll with OM1- Mk 3 and M1x.

The batteries are okay but the charger has a problem. The charge light stays red even after battery is fully charged. I know because after I unplug the charger and then plug it back, the light will turn green. I don't know if the charger is continually charging the battery which would be a safety concern. I contacted the manufacturer and they sent me a replacement charger but it has the same issue. After a while I decided to contact the manufacturer again, but this time I received no response whatsoever. The set is supposed to have one year warranty, but it is only good if they will actually honor it.
