Topic: CR2032 Lithium cells are rechargeable? (Read 45370 times) previous topic - next topic

I know this batteries are for long time using for example clocks or even PC's motherboard have one similar and they no lose they'er voltage; I also reed somewhere, I don't remember where, that the lithium cells are rechargeable for long durability.

Well it may look that I already know all about it but the true is that I'm not sure at all about it, I have some cells of this kind and they have 0 volts.

It may bee? or it is actually? or what?
Hope you all can answer me with out send me to search in Google.  =(
thank you all.  XD

I'm watching this CR2032 charger but there is something different they need lithium - ion cell battery

There are these CR2450 rechargeable lithium ion coin cells, https://www.sparkfun.com/products/10319 but you need special charging circuitry and discharge protection to use them safely. See the comments on the SparkFun product page.

thank you all

yes the rechargeable ones are the lithium ion and they'r LIR XXXX where XXXX is the number of the model, you know like LIR2032
well this is useful because I have a mini project with RGB led lights and they many need to fit in a little space (I'll use an attyny13) , a little porcelain home,  and I'll use  a mini solar panel.

by the way  my parents has a pair of glasses that has leds and they need 4 CR1632 well.

All batteries are rechargeable to some extent, the question is how well do they recharge.

In the case of a CR2023 the answer will be "terrible" - they simply aren't designed for it. You'd have to recharge very slowly (maybe a week) and it will probably only have a fraction of the charge of a new one.

Good to know that the LIR2032 can be re-charged as all the DS1307 modules I have came with those cells.

Hi,
    I have just found a rechargeable  CR2032 in the CPC (UK) Catalogue and only 89p+vat, but even so I don't think I need them as the normal cell last for years as an RTC backup, which is what I use it for, I suppose 2 could give you 6V for a very low powered stand-by application. Spec: 65mAh tagged for vertical PCB mounting, battery chemistry not stated.

That's a very expensive changer that is not really needed!  unless their Lithium poly or Ion!!  I would just tricke change them thro a resistor/diode, but then I'm a bit foolish at times.

Regards

Mel.

No, some are not, zinc-air and aluminium-air cells for instance cannot be recharged.  Many
that are not intended to be recharged can build up explosive hydrogen gas at high
pressure if re-charging is attempted, and can explode.  A rechargable (secondary) cell
is one that can be repeatedly recharged without hazard and without significant loss of
capacity.  Although you can for instance recharge alkalines to some extent they don't
fit this definition.  Even if the chemistry is reversible, secondary batteries require that
the plates reform in a mechanically sound condition upon recharge, repeatedly, which is
the tricky thing.

Obviously I mean the batteries we actually own and use every day, not some exotic ones that nobody's ever seen.

If you tap them while their growing on the tree, they will be...to an extent.

They are not intended to be recharged, but it's possible. I show how to recharge them with Arduino in this video: https://www.youtube.com/watch?v=XHJ2Up3U9AQ

Have fun!
