I usually buy Energizer AA alkaline cells because they are reliable and never leak. Duracell battery cells are a little more powerful but they leak all over the place!
A few years ago I was given free samples of Energizer Lithium AA battery cells that worked extremely well but they cost too much so I never purchased any.
Recently I saw Eveready Lithium battery cells at a very low clearance price so I bought the two packages of 4 cells remaining in the store.
Eveready is/was the founding company now called Energizer and they have the same customer support phone number. I asked customer service if the Eveready Lithium cells are the same as the Energizer Lithium cells and they said yes.
Yesterday I opened one package of 4 Eveready cells and mounted them in my project. Each cell measured 1.6V which is fine.
All 4 cells in the second package measured 1.8V each when powering my project with about 5mA which is wrong. How can they DOO DAT?
Customer Service is closed today because it is a holiday but tomorrow I will demand a coupon for replacements and I will let you know what they say.
It is odd that a Lithium coin cell is 3.2V but these Lithium cylindrical cells are supposed to be 1.6V. How?
EDIT: I put one 1.8V Lithium AA cell in my battery tester that has a 10 ohms load and it said GOOD. I measured 1.66V and it was slowly dropping. Without the load the voltage kept slowly rising. After resting a few minutes without the load the voltage is 1.69V and rising very very slowly. Tomorrow it might end at 1.8V again.
