Olympus BLH-1 Reviews

Older Stock Than I Expected

By Victor
Rated 4 out of 5
Date: 2026-04-21

I am disappointed that the battery I ordered on April 20, 2026 has a manufacturing date of March 9, 2023. Either B&H is not properly rotating their stock, or Olympus made far too many of these three years ago. The battery arrived partially charged, which is no surprise, considering the manufacturing date, but it did full charge on the Olympus charger.

Excellent

I am assuming, lithium. I am a consumer, end user. Not a scientist. Am not certain beyond the obvious. This probably doesn't help, but I really have no idea.
