Razor battery

[Ryan]

I recently replaced some dying NiCad batteries with another set of AA
NiCad batteries in my electric razor #1.

I am disappointed with how long they last. I recharge in 1 week or
less.


I have razor #2, also with a dying battery. That one uses a proprietary
looking 1.3 volt NiCad battery.

I'm told that NiMH will yield a more pleasing result. I'm also told
that charging systems rely on feedback from the batteries which they
charge.

If I mount two AA NiMH batteries in parallel in place of this single big
battery, need I worry about their ability to charge well enough for a
shaver? It doesn't seem to be much more than a transformer, some diodes
and a capacitor or two. I'm not sure that it is a "smart" charger.

Thank You.

Hi Ryan,

A 'Smart' charger will charge a battery in an hour. A 'Dumb' one usually
takes 10 of 12 hours.

A 'Smart' charger for NiCads won't work on Ni-Mh batteries. It will ruin
them

A 'Dumb' charger will charge both.


Batteries come in a lot of sizes,

1/2 sub-c 26mm X 23mm
4/5 sub-c 34mm X 23mm
sub-c 43mm X 23mm
