7.2 Volt 300Ma Rechargeable Batteries

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.

Purchased the DMW-BLC12 Rechargeable Lithium-ion Battery (7.2V, 1200mAh) as a backup for my Leica Q. Works flawlessly and entirely likely that the two are identical except for the branding printed on item (the two companies have a close relationship with one another). Lasts equally as long as its Leica-branded counterpart, fits perfectly in the Leica charging unit and seems to have no downsides. And for the price compared to Leica's own model, it's a no-brainer.

Quality rechargeable batteries.

These are the best rechargeable batteries I've ever used.

Rechargeable batteries - Great Life!!

The only way to go! Rechargeable. Why use batteries that need to be disposed of?

Good rechargeable batteries and charger.

the Eneloop Pro rechargeable batteries are the best there is.

Great buy on quality 9 volt batteries. My smoke detectors use 9 volt batteries.

Ive purchased two IDX 7.2 batteries so far and now Im about to buy another one. Im good with the the two but because its on sale Im adding a third one to my arsenal. I have been using the IDX 7.2V  for about 7 months now video recording news and shooting live shots. Im very happy with it, I can get almost 3 hours record time in the summer and about 2 hours in the winter. I used these batteries with the   AJ-PX270 microP2 AVC-ULTRA HandheldCamcorder I havent had it a year yet but for now I would recommend it especially if youre using it with the Panasonic AJ-PX270.
