If you have a \"smart\" charger and want to stick with it, there are NiMH
cells out there with capacities up to 900mAH which could be used with
the same charger - like this:

I believe Charlie+ is correct is saying that if you want to use
rechargeable Li-ion cells, you will need a different charger. If you
stick them in a \"normal\" charger\" it will just tell you that you have a
dud cell. I have seen them with capacites up to 800mAH
Alternatively, there are some Li-ion cells out there which have a built
in charger, and a USB socket on the base, which means that they could be
charged in situ ?
like this:
https://www.ebay.co.uk/itm/PP3-9V-Rechargeable-Batteries-USB-680mA-6f22-9volt-Recharge-Lithium-ion-Battery/143784853806
I would be interested to hear from anybody who has any of these.
Out of interest, you may like to note that I have a couple of Uniross
NiCD PP3 cells, which must be at least 10 years old, but seem to still
work ok - the downside is that the capacity is only 120mAH, but thats
enough for a few hours service on wireless microphone system.
The main point being that all of these current rechargeable solutions
offer at least 4 or 5 times the capacity of the originals, so theres no
need to even think about buying something with a capacity of only 200mAH
Also, dont forget that the original \"dumb\" chargers had insanely low
constant current charge rates - I have one which runs at only 11mA. At
that rate it would take at least a week to charge one of the latest
generation NiMH cells

The spec for the Trantec model I have quotes a battery drain of 50mA -
so you were spot on with your figure.
A while ago I bought a new battery operated doorbell - one of those
\"ding dong - Avon calling\" things, which has a single solenoid which
moves out to hit one chime and then gets the other one on the way back.
I was astonished to see that its powered by a 9v battery, and yet more
astonished when I discovered that the 120mAH NiCD will deliver the surge
current required to shift the thing, whereas a 300mAH NiMH will simply
not do the job. I have tried this out with 3 different NiCDs and a
couple of the NiMH cells and the results are consistent.
Obviously the cells are in reasonable condition and have been charged to
death prior to the tests.
Out of curiosity I am going to try out with Li-ion cells to see if the
story is any different. Maybe theres more to this lark than meets the
eye, and its not just about capacity.

Gotcha, I was skimming too quick that day. I see the ones you\'re talking about

Gotcha, I was skimming too quick that day. I see the ones you\'re talking about
now. After a closer search, I realized the Li-ion 9Vs I saw then weren\'t Amazon
Basics brand -- though they \"looked\" like the Amazon Basics at first blush (same
color scheme).

That\'s what impressed me. I didn\'t really expect them to work as well for me as they
do at a pretty low price point. They might not be the right choice for a heavier
user though.

==================
I\'ve had some decent results with the Amazon Basics 9Vs, but I\'m not
a very heavy user. My DMM uses one, and the others are primarily for
final testing a type of guitar preamp that I repair for people.
** Those are Alkaline types, so non rechargeable.
Ah, my mistake, I was unclear.
The ones I\'m using are the Amazon Basics Ni-MH variety.
** In a DMM ??
Don\'t you get tired of having to recharge it ?
Well, no.

I didn\'t notice they had Li-ion ones as well when I bought a set.
** Not Li-ion, non rechargeable lithium.
There are lots of sub types of \"lithium\" - most commonly they are 3V
cells.
So three inside a 9V unit.
