#45 - 9V Li-ion batteries: capacity testing

Several types of 9V Li-ion batteries were tested. Some of them performed quite close to the specs, some quite far. One failed altogether.

Ended up purchasing the EBL branded batteries, but could not find any source or info if they were protected or not so I took one apart. I can confirm the ones I got are protected, and the two polymer cells appear to be "genuine china" - branded with date code and manufacturer. They are labeled "SHJY 702335 600mAh 1605", and from my research I found its a company that acutally makes batteries for a living, and not rebranding other used or bad cells.

Thank you for the testing. I just bought an EBL Li-ion 9 volt charger and two matching batteries. I've had good luck with EBL batteries, and will be buying more in the future. Keep up the great work!

I have purchased many EBL 9v batteries to use with wireless microphones for our church choir. Duracell 9v batteries are rated at about the same 600 mAh as these EBLs. I connected a computer cooling fan to the Duracell and measured the time it took for the fan to stop. Then I did the same with the EBL. It lasted virtually the same amount of time to discharge, so I concluded that they do deliver the mAh they claim. I did over 70 cycles of charge and discharge on the computer fan to try to ruin the battery. I got bored of trying. I marked the battery with a "T" for test to be able to recognize it among the other batteries we have. The thing is still holding its charge and we still use it regularly after 3 or 4 years of use. After my initial purchase I have done another two sets of purchases of EBL batteries and have no complains. The Ebay seller I purchase from is called photoadd, they have been prompt and reliable. Hope my comments help, God bless you all.

Excellent review. I have one of those Soshine 9v batterys and always doubted that it delivered the stated capacity - so it's nice to see a proper test of it!

Excellent review very comprehensive testing. Thank you for NOT adding music. I look forward to watching your other videos. Subscribed!

[SoundSpeeding]

Definitely enjoying those Soshines for a number of years now!

Thank you very much for an accurate, informative, educational and entertaining review.

Thank you very much for your work. Looks like I'm going with the EBL.

Thi is the best video concerning the test of 9V batteries! Thanks a lot for your time! I bought the EBLs and hope they are as good as the tested ones.

Incredibly helpful video, thank you kindly!

Thanks for sharing. I think it would be better to compare different battery with same discharge current (eg 120ma). Even for the same battery, using higher discharge current will give lower mAh rating, and the capacity they quote may test at much lower current level, as the load current for typical application seldom reach >100ma

Straight to the point and good information thank you.

Thank you for the video. The problems are not the objects, however, are from the where we have to purchase the components and items from it, and this country's morality.

Sweet video man. I just bought the EBL 4-pack. Kick ass. Wonder what % the Energizers' do.

Conclusions just buy EBL 9v batteries, all others are fake branded, overrated :D I needed 8 of those, excelent video man

In my experience, high-capacity ratings are either: A. Complete fiction, or, B. valid at lower discharge rates (high internal R). It'd be interesting to retest the "900mAH" unit at some fraction of the current you used... Though all of them would show some improvement at lower current.

Thanks for a concise and an informative evaluation. You helped me decide my buying choices. You should work for a consumer research magazine!

[pinkythebrain]

Thank you.  Soshine and EBL are Chinese branded battery, the rest are generic.  So I know which to buy.  Thanks again for a good testing.

.. thank you nice informative helpful video !

This is good testing. You get gold star. Now i go back to vodka. Salu
