Bundle Star * Patona Battery for Olympus BLN-1 (real 1050mAh!) With Info Chip (latest generation 100% compatible!) To Olympus OM-D E-M5 (Electronics) 5
For my Olympus OMD EM 1 I bought some replacement batteries, both original batteries and these batteries Patona for Olympus BLN-1. I can not tell the difference of Patona battery to the original battery. This battery is priced much cheaper comparable performance-wise with the original and therefore gets a strong buy recommendation.
