Any battery you get other than a genuine Olympus, is actually going to be a 7.4 V rather than 7.6 V battery. That's not a huge issue, except that it means that the Olympus charger won't charge them. In some cases, like the Maximal Power batteries - it will partly charge them, but not fully. In other cases, it won't charge them at all.

I use a Maximal Power and an UpStart clone battery as well as the Olympus. They are each OK if you use a charger that works with them
 
I bought a couple of EXpro batteries and they use the Oly stock charger just fine. I would not buy a battery that needed a special charger - I have enough of those things for various devices as it without having to have two chargers for one camera!

you'd think by now that SOMEONE would be able to make a 3rd party 7.6V EM5 battery , the cams been out over 2 years !

These are the EXPros I found (a while back) . I couldn`t see a voltage on the battery . the ad says "100% OEM compatible" but don`t they all

No. When I said 'white expro' I meant ... er ... white expro! expros that are white. As opposed to expros that are not white. Capisce?

They were the only EXPros I found at the time , and knowing how colourblind the Welsh are , I guessed grey was close enough - I also Doubted EXPro would be daft enough to sell a battery which doesn`t work if they made one which does ........

Thanks for the link

The only issue I've noted is that the Wasabi batteries have somewhat less capacity than the OEM's. However for ~$25 for two (with charger), hard to beat from a value point.

If "somewhat" means 71% of an Olympus battery capacity, then you're right.

Doug is correct. Any batteries that charge in the Oympus charger are only partly charged because of the mismatch between the safety circuits for a 7,6 volt Olympus battery and a 7,.4 volt generic. You MUST put them into a generic 7.4 volt charger if you want them to charge to their designed capacity.

All these lay comments about generics working fine in the Oly charger are misinformed. Sure they work, but you're not getting the full charge. If you measured them or did shot count comparisons, or do what NCV does with his load tester, you would see what's happening.

And by the way, putting the Oly battery in a generic charger leaves it undercharged too, by about .2 volts. Doesn't sound like much, but it's a big number when you look at the working voltage on a battery. They don't get run down to zero. Instead they shut off around 6.8 volts.

Bottom line. If you use alternative batteries, get a generic charger too. Like Doug says, they all need their own charger for best performance.

AA's, even the best alkaline, can't come close to Li-Ion for energy density. Without the Li-Ion technology, µ43 wouldn't exist - the battery packs would be substantially larger.

I remember my Oly E20 that would run on 4 AA's, but ate them for breakfast. They didn't last very long. And that was the relatively slow, low powered E20. With today's EVF's, IS systems, etc... the lifespan of AA cells will be even shorter.
