Legitimate Battery Test across all brands

Although he is only testing AA's in this video (I have asked him to test D's) It is a very interesting test in deed.

There were some minor variations but the results are pretty much in line with my expectations and experience. I only use alkaline & lithium regardless of cost of mA/penny cost because there is one factor that wasn’t considered which is that depleted batteries pose a serious corossion risk to the device. In fact, the bounce test pretty much gives a visual demonstration which is that depleted cells will have increased internal pressure due to a chemical change of electrolyte. Cells that require more frequent replacement means there’s more opportunities for leakage simply because the cells will dwell more in the discharged regions than cells with more capacity. For that reason alone, the lithium cells are awesome. Unfortunately, they only come in AA size, nothing larger that I’ve seen.

I had an entire pack of brand new Duracell AAAs leak - all within 1 month of purchase - they still had years and years before expiry!

I think the thing that surprised me in this test is that the Energizer's beat the the Duracell's. I always put them on the same level. Not the case at all.

I've always been able to get Duracells cheaper than Energizers, so I guess now I know why lol

The Duracells tailed by less than 2% at worst, but that's what Costco stocks, so they win.

On more than a couple occasions I've had AAAs farked right out of the box, no corrosion, but they measure somewhere between 0 and -1V instead of 1.6V.

No Alkaline batteries for me. Too much risk on leaking batteries. I only use rechargeable NiMH batteries. In the long run you will save money and have almost zero chance of leakage. Add to that a lower internal resistance than Alkaline batteries and enhanced amplifier performance as a result, it's a no brainer. Alkaline batteries fade away in a linear fashion. If that's not enough, their internal resistance increases along with internal pressure. You truly only get an hour or two of good power performance and then they start to fade away. So until they completely die you only get a fraction of power output and it just keeps getting worse until dead....then they leak. No thanks. My NiMH batteries go at full power until exhausted.

I'm going on 5 years with my original set of NiMH Tenergy D cells and they still run my most power hungry box for 10 to 14 hrs.
