## Overview

The WEIN Cell MRB625 is a 1.35V zinc-air battery designed as a mercury-free replacement for PX625 and similar models. It delivers stable voltage output ideal for cameras and exposure meters, activated by removing an adhesive tab to allow air in. Its proprietary design with fewer air holes extends battery life up to a year, outperforming standard hearing aid batteries while maintaining eco-friendly credentials.

## Description

Wein Cell MRB675 is a 1.35V Non-Mercury Replacement for: MR44, NR44, EPX675, PX675, H-C, KX675, HD675, HC, V675PX, PC675, PC13, LR44, G13A, LR1154, RPX675, D76A, V13GA, PX76A, GPA76, 1128MP, 1166A, S76 It is designed to replace Mercuric batteries and is commonly used in cameras and exposure meters. Wein Cell MRB675 can be used in Minolta Hi-Matic C/G/7sII, Ricoh Hi Color 35/35s, Vivitar 35EF, Minox B/BL, Olympus Pen D3 and many more. WeinCELL MRB675 is a custom galvanized air battery designed to replace prohibited mercury batteries. Unlike 1.5V alkaline replacements, such as LR44, whose unstable output can produce exposure errors, WeinCELLs provide the same 1.35V voltage and output stability as mercury batteries. Unlike hearing aid batteries that last only 1 month, WeinCELL MRB675 batteries last much longer, typically nine months and sometimes up to a year. To achieve this longer life, the MRB675 uses a proprietary electrolyte and has only two small air holes, rather than the 7 larger holes found in standard hearing aid batteries. To use the WeinCELL MRB675, the adhesive tab must be removed. This allows air to enter the cell. After about 30 minutes, the MRB675 is fully activated and ready to use.

## Features

- Battery activated by removing the adhesive tab, giving long
- Lasts longer than equivalent hearing aid batteries due to reduced airflow
- Mercury-free for prohibited mercury cells
- Suitable for cameras and exposure counters
- The chemistry of zinc-air gives a stable tension during the life of the cell

A: Can't be certain but I would say yes, however they are expensive and don't last too long and given the meter is probably out of caliberation anyway I would say try the much cheaper 1.4 volt hearing aid better is which are very close in voltage and half the price for 6!!!
