batteries

[kurt stocklmeir]

I would like to know if all batteries that can be recharged get
recharged at the same speed

I am looking for a rechargeable battery that can get charge
extreme fast

thank you for any answers

** Only one I can suggest are Panasonic Rapid Charge types.

Back when I did some 1/10th scale car racing ( track and velodrome) Sanyo NiCd cells were the only ones that coped with 15 minute charging and 4 minute race times. The best were their SCR types.

Now, Panasonic make the same types.

No. It's not so much by chemistry -- there are both fast and slow
charging NiCd cells, LiPo cells, etc.

How fast is "extremely"? Getting a full charge on a NiCd cell in 10
minutes is doable. I don't think there's many LiPo cells that can charge
that fast, at least not without occasionally bursting into flame.

No, they are very different.

Extreme is a relative term.

You can easily find batteries specced for 8C charge rate:

That means that you can theoretically charge them in 7.5 minutes. In
reality, we're talking 12-15 minutes if you want them fully charged,
since you cannot charge at 8C all the way to 100%.

Since you do not specify any capacity or voltage requirements, a
cpacitor will handle extreme charge rates.
