1178.0. "AS8400 battery problem" by TKTVFS::YAMAGUCHI_KA (Kazumi Yamaguchi,CSC/Japan) Tue Apr 22 1997 07:40

	Hello,

	Battery life problem is occurring on AS8400 battery piu.
	This AS8400 system installed at end of December last year
	and battery end of life occurred at yesterday. There were
	NO power interrupt condition at customer site since system
	installation. All CEAG regulator detected battery end of life. 
	Voltage of all battery strings seems within specification.
	But date code of all battery strings is very old (4595).
	System serial number of the AS8400 is NI70401LZX.

	How is stocking the battery for AS8400 BBU-PIU at NIO ?
	How is keeping charge state during stock at NIO ?

	My worst fears is come again of battery problem on VAX/DEC7000.

	/Kazumi Yamaguchi
