بطارية ماكسيل SR44W أكسيد الفضة 1.55 فولت

My digital caliper wouldn't turn on with the old batteries, but these 1.55V silver oxide cells brought it right back to life. They're compact button-style cells that fit perfectly in the battery compartment.

My old film camera's meter was dead until I dropped one of these in—the steady 1.55V output is perfect for keeping readings accurate. Feels solid and fits snugly, no rattling around inside the compartment.

Installed one in my vintage light meter and the exposure readings are spot-on. The 1.55V silver oxide chemistry gives consistent power, unlike the alkaline cells I tried before.
