Title: Compatible with Canon 20D
Review: I read the negative reviews about the incompatiblity with the Canon chargers after I had purchased it and was afraid I would have to return it. Well, the battery charged with no problems on the Canon CG-580 charger which came with the Canon 20D. I did not clock the charging time on the Sunpak, but it took about the same time as charging the Canon BP-511A. The Sunpak BP-511 works perfectly in the Canon 20D. I have no regrets on buying it especially when it's half the price of the Canon and works the same.
