Canon EOS-1 Ds LP-E4 Battery Replacement

My battery died a first for any Canon camera I have ever owned and I'm having trouble finding a factory battery replacement for it. I see a lot of aftermarket batteries for it, so I wanted to ask the brain trust which is the best that last the longest?

Thank you

I ordered a Power 2000 from B&H today which is a replacement battery for my camera but is rated at 10.8V and 3600mAh and the original battery from Canon the LP-E4 is rated at 11.1V and rated at 2300mAh. Will there be a problem with the higher mAh rated battery for my camera?

Should be no problem at all. It will shoot 1.5x more pictures. Enjoy.

10.8 vs 11.1 is the same. Both 3 cell packs. It's just the nominal voltage.
Most of the extra mAh is not real.
Canon pack probably has 2900mAh or 3100mAh cells.
The replacement you are looking at would have 3600mAh.
Canon rating is much lower as they have a good safety margin, shutting off pack long before it's completely depleted. Therefore the body won't let you have all of the 3600mAh.
