I'm trying to figure out if I should get 1 x OEM olympus battery ($60 here) or the 3 x DTSE non-OEM batteries that come with a different much smaller charger and car charger ($35 shipped on eBay). http://item.mobileweb.ebay.ca/viewitem?itemId=200834819339 The smaller charger is a definite plus for DTSE. The DTSE shows the battery status on-camera like the OEM version. The MAIN negative I've read about the DTSE is that they don't hold a charge very well if left unused (I often go in spurts of photography). Anyone have thoughts on whether the DTSE claim regarding holding a charge is exaggerated? If so, I'll likely go for them based on cost and the much smaller charger. Thanks!
