I’ve also had the Energizer Lithium primaries completely discharge in just a few weeks from installing them in torch.
No parasitic drain was responsible for this. Had it happen twice on two different torches.
Needless to say, my confidence in Energizer lithium primaries is not very good. To be fair, it happened to only two batteries out of the 12 that I had.
To anyone reporting similar instances, can you please include either the build date or expiration date of the cells you had troubles with.
I use L91’s in a very expensive piece of equipment ($900+) and would like to avoid having to test out that guarantee myself…
Build date is a 4 digit code stamped in the case near the negative end (not printed like the labeling / expiration date) but easy to read when viewed at an angle.
I’ve seen a lot of situations where the + end of a cell and the spring touching it became corroded. Often enough corrosion goes right into the case along the + wire to the circuit board.
I’ve noticed that happening on all sorts of things — flashlights less often than little radios and electronic thermometers/humidity meters/clocks/calendars, for example.
I’ve wondered if this isn’t because some current was flowing even with the device switched off.
It’s one of the reasons I’ve consistently used Energizer lithium primaries on anything I valued.
i run energizer lithium primaries inside all my backup/emergency and bugout system, out of several devices like double or single AA flashlights, beacon light, M26 taser that runs on 4xAA and baofeng two way radio with 6xAAA adapter cases and lastly emergency ceiling lights/bunker lights that runs on AA or AAA batteries
im not sure how this happened but it was found in one of those devices since i run a test and check on them each month, luckily i discovered it before it would further cause damage to my device
out of every hundred you’re gonna expect a few failures i suppose, yet i cant rely on eneloop due to my higher powered devices requirement(especially baofeng and taser) eneloop tends to discharge itself down to nothing after at least 3 years so some of us will surely stuck with the imperfect lithium primaries which energizer or NICE brand produce
2- Energizer Alkaline (they are the standard alkaline, black label)
3- Energizer EcoAdvanced (they are new alkaline type, silver label)
The energizer Lithium, are made in Singapore. They have “vent holes” in the + pole.
The energizer Standard alkaline, are made in Singapore. I can not see “vent holes”.
The energizer EcoAdvanced alkaline, are made in USA. They have “vent holes” in the - pole.
The ones made in USA seems the be better built than the ones made in singapore.
I can see more variants of energizer alkalines at the stores. Will check them. But I can not find a “no leak guarantee” variant here.
None of my energizer lithiums have leaked or died in any way. (But I had the ones from fasttech branded as “nice” that were at ZERO volts after 1 month without being used…. only used a few minutes in a flashlight…weird…)
I have had a few energizer alkalines leaked… but other brands leaked even more…
Well, finally Energizer has informed me via email that they will be sending me check within 21 days, as property damage, in the amount of a staggering $20!…btw, up from an original amount they offered of $10!!
That is after 22 back and forth emails.
Nothing much different from some Chinese vendors, mind you!
Not much different from a Chinese vendor… But I assume you were hoping for something better?
People keep asking why I would order direct from China and I say because the big stores do it and provide no added value. No expertise, no customer service, and not much for warranty. Why not just order direct and take your chances?
Your experience pretty much tells me that energizer does not value their name and their guarantee is nothing more than a marketing scheme. Too bad.
