I have this battery grip and haven’t experienced the issues it’s suppose to have. However my serial number falls in the range of affected units, so I should follow through and get it replaced/repaired in case it something that could show down the road.
Canon USA has announced that customers with the Battery Grip BG-E2 used with the EOS 20D and 20Da, and a certain serial number range can return their grip/magazine for a free repair/replacement. This is due to a cases where even with fully charged batteries (exclusive battery pack or NiMH battery) or unused AA size batteries, only a few shots can be taken or ‘bc’ is displayed immediately.
