Replacement Charger needed

[Crazy Dave]

The charger for my wife's EM-10 Mark 1 has gone walk about. Would welcome suggestions for sourcing replacement.

Thanks

Thanks Peter, it's on order. Much appreciated.

Re: Replacement Charger needed

It doesn't appear to have the thermal protection pins on the original Olympus charger. I have a feeling it won't charge the batteries as high a voltage as the Olympus either (the cheating way of staying safe) which means it might not have as long a battery life (number of frames) as they used to.

For myself, I prefer to stick with Olympus battery & charger.

Thanks for this, I'm hoping that the original will turn up in the house but we needed something for this coming weekend. I received notice of despatch from Expro just an hour after I placed the order. So far, so good.

Re: Replacement Charger needed


I wasn't talking about the current but the voltage which is 8.35v (& at 0.4Amps) on the Olympus BCS-5. The maximum for the BLS-5 battery is 8.4V at 760mA although it is rated as a 7.2V 1150Mah (min 1080mAh) battery. The specs looks like it might be good for charging 2 (active) terminals after market batteries (that don't use the internal temperature connections system) with the soft start, constant current etc. Maybe it will charge the Olympus battery & the issue was with after market batteries not being able to charged in the Olympus charger.

No knowledge of 3rd party chargers but with Ex-Pro and other 3rd party batteries I've noticed no difference in number of shots on any of my cameras.

Some mixed thinking here Ross.

The 8.4v at 760ma is the maximum that is safe for a charger to apply to the battery, so a charger which can provide 8.3v at 400ma is fine. The 7.2v is the terminal voltage produced by the battery and is a function of the battery chemistry. In order to charge a battery a charger will have to apply a higher voltage than the battery produces otherwise the battery will try to charge the charger. 1150 maH is the capacity and means it can produce (in theory) current between 1ma for 1150 hours and 1150ma for 1 hour.

The previous "issue" was indeed the inability of early after market batteries to be charged by the Olympus charger which will only work if it can communicate with an appropriate "chip" in the battery. Later batteries from ExPro (and others) now have an appropriate "chip" and will charge from the Olympus charger.

I have an ExPro charger for my BLN-1 batteries which was supplied with the early batteries for this reason. The charger is a "universal" one and the only difference between mine and the one I quoted for David is the "battery plate" which has to match the physical profile of the battery.

Thanks Peter. Yes I understand the first bit but just didn't write it too well (after rethinking & editing). It's good to know these chargers can work well then.
