Review: I really love these batteries! - I did an outdoor shoot 4 days ago for over 2hrs, consistently shooting with only ONE battery. The battery still has not discharged🤷🏾‍♂️. I DEFINITELY recommend these💯!
Review: Charge Batteries Before Using - In my observation, as a photo hobbyist, these Kastar Brand Rechargeable Batteries need to be charged before using. On my charger, which you can also buy on desertcart, the charger lights stay red for a long time, when new out of the package, meaning the batteries need charging. When the charger lights turn green (at about 40 minutes, or so) they're fully charged and ready for use. Whatever charge that is in them out of the box may not last a session. I always charge them first. I've used these Kastar's for quite a few years now and they're very dependable batteries, but remember, a long or short photo session will burn a charge quickly. Which is why it's good to have plenty of Kastar Rechargeable Batteries on hand. Traveling? Take at least 4 Kastar's and your universal USB charger if going to a theme park or something to travel light. Camera's are Olympus "OM-D/ E-M5" and the USB (plug anywhere) Battery Charger, both sold on desertcart as well. Buy with confidence! Nora's spouse, John -

### ⭐⭐⭐⭐ Works okay on first few charges
*by T***M on October 19, 2018*

So far so good, haven't tested long term but works fine on first few charges. I don't expect the life of this battery to be as per original, I've used these also before, but it provides additional backup esp when traveling.
