Replacement for Olympus BCS-1 Battery - Compatible with Olympus BLS-1 Digital Camera Battery (1150mAh 7.4V Lithium-Ion)

La batería me llegó en excelente estado, funciona al igual que la batería original de mi cámara Olympus, carga rápido, sin calentarse.

Be very wary of this UpStart brand! As a advanced-level photographer, in the past I would invest hundreds of dollars (USD) in OEM replacement batteries, but after a while I began trying different (what I thought to be) quality 3rd party varieties.I'd say that over the past 5 years, I've purchased around 50 of these UpStart brand batteries for a dozen different cameras (different brand models). At first, I was stoked that I managed to get so many batteries for such a low price. After all, I heard several folks giving them high praise on various photographic forums - but I soon discovered that offering that praise right after a purchase is, I find, to be a bit too premature. Please read on...After about a year, I began noticing that the UpStart batteries began to swell quite significantly, and the next thing I knew, I had to begin discarding these batteries in the trash. One by one, the same issue would arise with the passage of time, especially if not using them for a few months (i.e. left fully charged in your camera bag). And when not using them for several months or more, around half would lose their charge, and in many cases, would be unable to be recharged.I couldn't believe this - such a disappointment. One of my cameras - a Fujifilm X-T2 had one of UpStart's W126 battery inserted and I had a very difficult time removing it because of the swelling.So, to make a long story short, every single UpStart battery I had (for Canon, Nikon, Fuji, Olympus and Panasonic), had to be eventually discarded in the trash due to an abnormal amount of swelling, or lost their charge, and could not be recharged again. My Wasabi's and Watson brand - even some of which had the same issue - were, overall, much more reliable in the long term.So what I'm suggesting is that although in the beginning you might be impressed with UpStart brand (they come in really nice packaging, giving you the impression of high quality), it won't be long before, in most cases, you wind up throwing them in the trash for the problems mentioned above.I've now tried 3rd party batteries from over a half-dozen different brand names, and I can honestly report that the UpStart brand was the worst with regard to swelling, being able to hold a charge, and eventually not being able to be recharged. Take this information as you wish - all I can do is report my extended time period use experiences with these. If I could give them less than just 1 star, I would. Now I realize that all reviews are subjective, and perhaps, no two folks will agree. After all, your usage may vary and you may very well like yours. All I can report upon are the experiences I had with this brand.

It was exactly what my camera needed, an extra battery. Went on a trip and knew that my one wouldn't last the entire day. This was charged and ready to use!

Works good and has a higher amp hour rating that the stock battery.

Gracias!
