Just seen in electronics products catalogue a device for measuring the
capacity of lead acid rechargeable bateries in seconds, giving readings in Ah.

Does anyone know how these devices work ?

I would assume a brief high current discharge pulse and measure a voltage,
and perhaps depending on the voltage at a given current drawn we could
some how determine the capacity; if this is so are there in existence tables or
charts from which to extract the relevant information ?

Any internet sites ? Ive looked but not found the desired info.

Any help most appreciated.

Thanks

Andrew Farrar
