Duracell. Energizer most avail, but bad reviews. I buy on Amazon.
Amazon is hit or miss. Most sellers won't ship lithium batteries here, and others are bogus items -- i.e. they take cheapo batteries and relabel as reputable brands. Others may even be "seconds' that didn't pass inspection at the Chinese factory that made it, so they dump them for cheap on Amazon.
I've started frequenting Battery Bill's. They tend to not only have the best quality batteries at reasonable prices, but often the one they recommend as a replacement is a larger capacity than the old one for about the same price.
I have to assume a company that sells almost nothing but batteries already knows which ones to avoid and isn't having to deal with the "we don't ship to Hawaii" sources.
I just replaced 2 old iPod batteries and two Samsung cell batteries. Perfect fit on all devices, and in the same ballpark as the ones on Amazon and eBay. And if I have problems with them, I can deal with a local seller vs. Amazon or eBay sellers which might involve return shipping costs -- assuming i can ship it back.
Recommend calling Bill's. If they don't have what you need in stock, they can order it.
