Charging NiMh batteries when not completely discharged

[Andy]

I would think in terms of overall costs, that nimh would be cheaper than buying alkaline aaa batteries. My "alkies" last about 6 months. I have charged the nimh ones about 3 times. My charger charges them separately.

It would help me find relevant replies if so many were not littered with arguments and cussing. Thanks,Andy

I agree. The price on rechargeables has come down, chargers have
gotten much better, and the low self-discharge make them hard to beat.
(and you aren't storing a lot of alkaline batteries so you have them
on-hand when you need them). (I store batteries in the refrigerator
so space counts)

Amazon has their house-brand rechargeable for ~$12 for 12 AAA
batteries, and EBL $24 for 16 AAA and an eight station smart re
charger as a package deal. Eneloop is $28/12 batteries.

Amazon house brand alkaline is $20/100 AAA size, and name-brand
~$40/100 (sounds like a 1-2 year supply for me)

** Then you would be thinking wrong.

It is ONLY in high usage and high current applications that re-chargeables come out the winner.

For items like remotes, clocks, DMMs, rarely used torches and any low usage item - forget NiMH cells.

That it would, PHIL.

I use Eneloop calls in my remotes and not just for the savings or reduced waste over using
throw-away cells. I've had more than one remote damaged by leaking alkalines and am yet to see an
Eneloop leak so there's that...

I use a Maha One charger / conditioner which is also great for matching cells if you need to run
them in series.

The aaa alkaline batteries went out on my tv remote.

I decided to use my NiMh UBL aaa batteries. 1100 mAh.

They are currently showing 1.31 volts.

And they work ok in the remote as is.

Not a surprise; alkaline cells when fresh are 1.5V, but are useful down to about 1V.
NiCd and NiMH are 1.2 to 1.4V fresh-charged, useful down to about 1V.
Li nonrechargeables are 3.6V fresh, useful down to 3.0V (so can replace
a 4.5V alkaline clock battery, or two in series can replace a 9V which has 6 alkaline cells)


My charger is the manual type.

It charges that type at 150 mA.

I want them fully charged since they are 1.2 volts versus 1.50 for the alkaline.

Don't use rechargeables for best shelf life, but for best total life.

Mainly, your remote control is inert (it gets used in subsecond bursts when you press
a button). The self-discharge when not in use (and higher purchase price) make
rechargeables a questionable fit for that application.

I already had them, so decided to go ahead and use em.
