4 Volt 1.5 Ah Battery

[Active 3-Way] worked just like the product I replaced except uses a double A battery instead of a nine volt.

[0.15 lb] The Exell A32PX 6 volt alkaline battery is a direct fit replacement for the old mercury battery used in the Yashica Electro35 rangefinder 35mm camera. This batteries resuscitated the camera! The voltage is a bit higher than with the mercury, so you may need to tweak your exposure for critical work. With the Electro35 this is easily accomplished by changing the ISO (ASA) on the original Electro35. Frankly, shooting regular negative film didn’t require any change.

[Alkaline] [This review was collected as part of a promotion.] These 9 volt batteries are packed with energy. A great battery that fits perfectly. I was able to use this battery in my smoke detector and it’s all fixed. Rayovac brand is one I confidently trust and know I can rest assured my batteries will keep working.

[2 x 1 x 0.15"] I'm so pleased to find a fresh 6 volt silver battery to restore the functions of my Minox 35 GL. Now I'm looking at many more years of service from my pocket camera.

[Unity 1x] I do not believe I have ever reviewed a flashlight before. This one is a neat convenient package. Interesting too that it has a 9 volt battery. Works well with a rotating switch. I like it give it a try

[0.495 lb] One of the Q&A’s says the Bescor BLS50AC dummy battery adapter kit is not compatible with the Olympus E-PL9.  I asked Bescor ( answers@bescor.com ) why the kit is compatible with the Olympus OM-D E-M5/M10, but not the Olympus Pen E PL9, since all three use the same Olympus BLS-50 battery.   The response was: “It will work. Your camera just needs to be added to our list.” The Bescor is 8V 3A. The Olympus battery is 7.2V 1175 mAh (1.175A).  I did some online research to see if a device built for 7.2V could operate at 8V.  One person describing himself as an engineer posted that 7.4V Lithium batteries actually span a 6V to 8.4v voltage range depending on state of charge of the battery.  Another “senior electrical engineer” said that because all devices are designed with some voltage tolerance value, a 7.4 volt device means 7.4 volt +/- 1 to 1.5 volts.  Still other posts indicated that you can use a 3A power adapter on a 1.5A device.  By logical extension, I figured (I don’t actually know) that since the PL9 uses a 7.2 volt battery, it is probably designed to also work at 8 volts, and is also okay running at 3A. Based on the response from Bescor and the Internet voltage and amperage responses, I decided to purchase the Bescor and use it with my PL9.  I haven’t seen any sign of overheating or other problems with this setup so far, but will update this review if that changes. I did not deduct points for the need to leave the battery compartment open because I knew that would be the case when I bought it.

[1.275 lb] I needed to update my Canon battery charging. The plus is the 5 volt output to charge phones and other devised!

[6 x 3.9 x 1.5"] The battery charger that came with my Canon Rebel was 110-Volt only. On a Smoky Mountain vacation, my installed battery went dead and there was simply no place to charge it. This charger allows you to charge the battery by way of the cigarette lighter. No more will a dead battery stop me from my photography and I thank the B&H people for leading me to this alternative battery charger
