What is the max current to draw from?

[PrebKlok]

Does anyone know what the max continuous current/max peak current you safely can draw from a CR123A-lithium, AAA, AA, C and D alkaline batteries?

check datasheets. I suggest you www.gpbatteries.com

I don't think it's so much an issue of maximum as diminishing returns. Push it harder and you get less of the total (much shorter run time).

As suggested, check the specs. The graphs show this in detail.

The Duracell OEM page has lots of useful graphs.

For the CR123 the first graph shows how many watt-hours
you can get versus the load's wattage (link).

The second last one (voltage vs time for various current
is also useful).

I assume the data sheets for their other cells contain
similar information.

There are some "quick and dirty" practical limits.

- Li 123 and D size Alk - about 1 amp
- AA and AAA Li enhanced primary cells - about 0.5 amp
- High end AA Ni based recharge - several amps

There are some lights that pull 2 amps from a 123, but overheating is possible.
