D1 series battery issue

I'm using a D1h with the latest firmware, and one of my batteries is acting up. It

indicates half full, and the shutter won't release. Upon depressing the shutter

release button, the battery indicator flashes. I have refreshed the battery twice, but

it still won't allow shutter release. It is now on the charger for a third refresh (two

consecutive charge/discharge cycles).

The other battery from that batch (they are Lenmars version of the NiMh EN-4)

bought the same time works fine.

There was one time I removed the battery during image deletion because the

camera had pretty much slowed to a stop...but I'm not sure which battery it was,

or how having done that might kill the battery.

Any advice or anyone who has experienced a similar flashing half-battery indicator

on a D1-series body?

Thanks.

I've had the exactly same problem. I jus tthink that the some of the EN4 batteries

just won't work with the D1H for some reason. There was nothing for me to do, but

return the battery after first having got it replaced and had the same problem. And

since look elsewhere.

I also have the latest firmware, 1.5. I don't know if it matter though.

My current batt is an noName but it works fine.
