Once DC buss 1&2 are lost the battery will power some essential services. The essential services busses can be used, but with limited systems, the anti coll is not on the list.. A rate of decent around 2500 feet per minute would give around six seconds before impact from that height, so not much time to do anything other than get the engines to off, not even time to get the switch made to get the gear down.
