This replacement mercury 1.5 volt 350 mAh battery is made with high quality parts and is guaranteed to meet or exceed the original equipment manufacturers specifications at a reduced price.
Our alkaline replacement for the once available Mercury Oxide MR52 (or now the PX640 type) cell used in cameras (Yashica TL-Electro, Electro 35 FC, Lynx 14-E and Lynx 5000E). The MR52 (or now the alkaline PX640, AG 640, EPX640, A640PX, V640PX) was used in some rifle scopes by Hakko. Mercury cells are now banned in the USA because of toxicity and environmental damage in landfills and water sources.
Just bought a Yashica Electro 35 GX and needed an alternative to the original mercury batteries. So glad to have found this affordable option. They work perfectly!
Great product, good prices and fast and efficient service from the folks at Battery Mart, highly recommend
I couldn't find a battery for my scope anywhere. Batterymart did.
Have been using Tasco Pro Point sights since the first model came out over 20 years ago. The original RM640 mercury batteries are long gone, and it's nice to have an alkaline replacement that works as well as the original. The current 640s are long lived, and well constructed.
Batteries no longer carried by local battery stores.
I thought I would never find replacements for the mercury batteries used in a tiny classic transistor radio. But Battery Mart had alkaline replacements that fit perfectly, and work great.
