A few weeks ago I posted on purchasing alkaline batteries for my emergency stock (rotating out old stock) I ran a couple of test 5 days ago on my old energizer alkaline batteries and was disappointed but not entirely surprised. I wished I done this short test before purchased the alkalines recently. So, with this outcome I'm going to make more changes.
My short notes on this.
I finally tested my American made energizer max alkaline batteries that were 7 years old and 9 years AA and D cells, The voltage has dropped to 1.3 for the AA 7 years old and the D cell 1.4 9 years old, the AA I put in a 3 battery LED flashlight it worked and not a noticeable reduction in brightness but dimmed slightly in 5 minutes, but after 4 days in the flashlight it started to leak, the D cell's I put in a 4 battery lantern, the lantern was totally reduced in light output and died in 10 minutes.
With my test the 10 year holding power may be true but not under load, also, the guarantee of not leaking take with a grain of salt, in a SHTF guarantee means squat, the 7 year old AA leaked after 4 days after being installed, not exceptable in an emergency.
My energizer lithium AA after 6 years in storage still had full power and worked the flashlights just fine. I'm going to start rotating all my stored Alkaline batteries out replacing them with energizer ultimate lithium batteries AA/AAA. Yes more expensive but more reliable in both power output and reliability and that's what I need in short term and long term emergencies.
I also have eneloop batteries, but the eneloops are in case all other batteries are exhausted and not available for purchase.
