Px27A 4Lr43 4Sg12 Alkaline Battery Review

Thanks to my knowledge gained in practice, I can tell that this brand is reliable and the batteries last for months. They're ideal for all electronic devices, from remote controls to flashlights, and they don't corrode easily. The only downside is that they are slightly more expensive than other brands, but the extra cost is definitely worth it for the extended life.

Not compatible with Rollei 35 TE. does not make proper electrical contact. The camera meter works with the right battery, this battery just doesn't work. at least with my rollerball 35 TE it doesn't contact properly

I am sure that the battery I received is a good example of the battery advertised. Fast delivery, working battery. My fault but apparently the PX27M model number is different from the PX27 I need. The cell is the same voltage, size and shape but it has a flat end and a button end (like most batteries) whereas my application requires buttons on both ends (this is for an old Rollei 35SE camera). Hope this helps some. I know of at least one other instance of this confusion.
