Lithium Ion Battery Issues (Solved Garbage Batteries)

Recently made the whole house switch to rechargeable lithium 9 volt batteries.

Been fine...no issues. Until today.

Had a battery die in my Carvin...cool, got that. Wrong. Fully charged 9 volt..... guitar does not recognize it....won't pass a signal.

Went back to a spare alkaline I had in a toolbag....but not happily.

Guitar is from 96....and 9 volt is 9 volt.....maybe it's shorter and not making a connection?

Any insight?

Edit - TL;DR I bought trash cells. When "fully charged" they read 8.3 volts ....no gooda.

FWIW, from https://electronics.stackexchange.c...cant-i-power-everything-with-a-9-v-dc-battery

"The 9V battery isn’t designed for bigger stuff. Internally, 9V batteries are actually a stack of six tiny 1.5V cells connected in series. The internal resistance of that stack is pretty large, severely limiting the current that the battery can deliver.

Rather than powering your house, or the world, the 9V battery’s mission is to power small electronics like ‘transistor’ radios: that is, devices with a small current drain but in need of a higher voltage to operate. And for that it’s pretty darn good, if pricey.

The 9V battery: great for your smoke detector, not so much your toaster oven making the smoke."

And

"Realistically though, both science and economics limit the 9V battery use cases. A 9V battery is heinously expensive per unit of energy delivered, very resource-intensive to make, non-rechargeable in its common form, and limited in both energy content and power output."

Have you used a multi-meter to test that 9v? I remember hearing some years back, that rechargeables are not good for some electronic devices because of the amount of energy they can/not deliver at certain times. But I would first try a second 9v and test them to ensure they are outputting a value similar to the alkaline 9v's.

Good point. I will do that.👍

Cool story....my guitar only take 9v
 
They all measured 8.0

I am perplexed... I charged them before I stored them.....weird. 🤔

Stored in a plastic case...in room temp closet. Probably just crap cells to begin with.
 
You said you switched the whole house to 9v batteries- or so I thought. I quoted a piece that said that 9v batteries are not suitable to power a house.

I don't use rechargables for my ESP's active pickups because they always lack power.

No worries, not harm done to anyone...
 
Apparently if they sit too long they can discharge rapidly and lose charge....guess I will just get good ol NI-CD like old times.

:Boo

So you were being silly and I missed it?

Or you actually think I'm powering my house with 9v batteries?

I've been sick...a little slow here.

Whole house or some items within the house such as a guitar's active pickups?

Maybe I'm slow. Sorry. :beer

I suppose I was a bit unclear....

I apologize.

I switched the battery solution, for the items in my home, to rechargeable. The 9v I chose, were lithium ion....and they are trash ....so I am going to NI-CAD.

I had to convince the others in the house...which just meant I was responsible for keeping them all charged and stocked. Yep. Did it to myself. I'm just glad I had a spare alkaline.

These aren't active pickups by the way....hard to explain. It has dual output. Acoustic and electric. The electric has an active preamp....passive pickups. And the there is the acoustic preamp.....this is what requires the battery.
Carvin AE 185. Pretty cool guitar.

Also, :beer

I don't think it is that they are loosing too much charge, but simply even fully charged will never give you the voltage you need for the Carvin. As Blix pointed out above, a rechargeable is generally never rated at the output level an alkaline is. That is why some electronics have a warning saying to not use the rechargeables in that device (because they need the full juice). Now I figure you probably don't have such docs on the Carvin, but you may want to check on appliances you do have to see what their specs/guidelines say on the topic. Especially the smoke detectors. I am sure many of the devices you have converted to the 9v rechargeables will be just fine. The test is of course is, are they functioning properly and for a long enough period to satisfy what you are looking for from them ;~))
