Rechargeable batteries

Let me ask a dumb question about rechargeable batteries. Is it possible for them to die completely?. Meaning they would not charge at all anymore.
 
Not a dumb question at all! I have a lot of experience with rechargeable batteries as I have used a wireless mouse for years now.

First of all, not all rechargeable batteries are the same! Far and above, the eneloop batteries from sanyo are the best. They are well worth buying if you have a scenario where you will be using rechargeable batteries.

Second of all, not all battery chargers are the same! I use a La Crosse BC-1000. It has the ability to charge your batteries in a way that increases their longevity. Also, it can take batteries that are seemingly failing and retrain them. I think there are no real issues with the "dumb" chargers if they are of a respectable quality, but in my opinion, a good charger is worth the investment.

Regarding your question: Yes, it is possible for them to die completely. Depending on the quality of the battery and the quality of the charger used, rechargeable batteries have a limited number of times that they can be recharged. As I mentioned before, having a fancy charger can increase their life span.

Here is where it gets interesting though... my fancy charger will sometimes not charge some of my old, crummy energizer rechargeable batteries (telling me that they have failed). However, I found that if you charge them for a bit on a dumb charger, then put them in the fancy charger, the fancy charger can bring them back to life!

I'm pretty sure I have exceeded the proper life span of these crumby Energizer rechareable batteries by at least 1,000 recharge cycles, and they will probably explode or something soon =) But there you have it, WAY more information than you wanted =)
 
my energizers are corroding and dying. I'm moving to eneloops.
 
depends on the type of battery. I have a few lithium ion batteries that got drained so low that it didn't charge on the main charger. As TheHobbyist mentioned.. I have to put them into a "dumb" charger to get the voltages up to the point of working in the primary charger

Thanks for the great answers TheHobbyist. I am using Eneloops myself that i have gotten from Amazon back in 2013 as well for my wireless mouse . As for charger, i have XP-350 Power 2000.

As far as i can tell, you have a high end charger. :)

I still have Energizer AA batteries which are over 10 years old that still work great, made in Japan.
They still charge about 5% over their rated capacity.
As long as they are not in a wet environment and start to rust they generally can be charged some 1000 times.

Right now the Eneloop XX are the most powerful you can get.

They were Sanyo but Panasonic bought them out so now the new ones are Panasonic labeled.
 
If they improved the already great 3rd gen I can't see any issue, they made the best even better.

Any opinions on the Panasonic Eneloop 4th Gens?

Pricey compared to a set of disposable alkalines, but then they more than pay for themselves after a couple of recharges... like a lot.

All the gadgets around my house are loaded with Eneloops. The 4th gen Panasonic brand are a slight improvement over the previous gens - you get more cycle life out of them. (Good for roughly 2100 recharges vs. the previous generations 1800.) Other than that, they are identical and should last you quite a few years.

Unlike other brands, they also don't loose much charge sitting around. Great batteries.

Using expensive rechargeable batteries and chargers it's just waste of money.

LOL, how do you figure that? I have not bough a pair of AA batteries in 10 years.

Do the math at how much I have saved over alkaline batteries in that time.

BTW, they are not that expensive compared to Duracell alkaline batteries now.

Do you work for a company that makes batteries that are not rechargeable?

After a few charges, the batteries and charger pay for themselves.

And good rechargeable batteries give just as much use er charge as an alkaline.

Now back in the day when all you could get were crummy NiCad batteries, sure, it was true that i really wasn't worth it.

Oh, and by the way, any of your gadgets like cell phones, laptops, tablets use rechargeable batteries.

And so does your car.
 
LOL. I were talking about buying expensive rechargeable batteries. I am using a pack of 4 rechargeable batteries that i have bought for $8 on sale. Well maybe expensive rechargeables have a longer lifespan.

There is really no such thing as expensive rechargeable batteries with gold platted tops.

Buy Eneloops on Amazon, anything more expensive then they are is a rip off.

The XX version are a tad steep but they are also the most powerful Mah in their class
so they run a premium.
 
I just bought a bunch of Amazon Basics AA's and they work great, I think I got 16 for $29

The type of battery affects how long it takes but every single battery will die, so technically you're incorrect.

The question is, "Is it possible for them to die completely?" and the answer is, "Yes, all batteries will die completely at some point." Period.

I do recommend Eneloops. I have yet to have any die and I've had some of mine for probably about 5 years now.

no one is arguing that batteries don't eventually die... What was mentioned is that some types have a habit of getting so low that they don't take a charge unless they are put into a "dumb" charger to bring them back to life. This usually is not the generally the case with lattice tech batteries like NIMH Eneloops but does happen quite a bit with lithiums
 
Been using the eneloops myself for ~7 years now. Haven't bought a disposable battery since then (except for the furnace thermostat). Also haven't had a single one die on me, out of the 40 or so I have floating around here. Have lost the entire pack of Energizer brand rechargeables about a year after purchase. Stay away from them/Duracell.

This last year I've started switching to Imedion, they hold their charge far better in low use items.
 
Brought the Apple branded Eneloops a couple of years ago for my g700 mouse.
Came with 6 AA and a dual AA micro charger for $30.
Went the Apple route since I didn't want wait for delivery so I just went to Bestbuy.

Very happy with these Eneloops.
