5 x Volcell A640PX 1.5V Alkaline Battery PX640A EN640A EPX640A LR52 + Free Shipping Type: AlkalineVoltage: 1.5 VDiameter: 16.0 mmHeight: 11.2 mm Also known as: PX640A / A640PX / EN640A / EPX640A / PC640A / LR52 / 1126A. The PC640A or PX640A is a mercury-free replacement for the once popular Mercuric Oxide MR52 (or PX640) cell that was commonly used in cameras (such as Yashica TL-Electro, Electro 35 FC, Lynx 14-E and Lynx 5000E). The MR52 (or PX640) was also used in early Hakko rifle scopes. Mercury cells are now banned because of toxicity and environmental fears. The PC640A or PX640A cells produce 1.5 Volts, which is higher than the 1.35V produced by the original mercury cell. Most devices accommodate the small increase in voltage and function perfectly. The PC640A or PX640A is likely to be your only choice of battery replacement. Consider buying more than one. These Alkaline cells have a shelf life of several years, so buy two and make sure you always have a ready supply of power for your device whilst taking advantage of our reduced price multi-buy offer.
