New glow plugs = dead battery?

[ahuggard]

To continue the cold weather/starting/glow plug theme on the board, I contribute this question:

After replacing 3 out of 5 glow plugs, my engine refuses to turn over and has no juice left in the battery. Would changing said glow plugs hasten the end of a weak battery?

I tried to jump the battery, but it did no good. I will head out to get a new battery tomorrow, but should I be wary of the starter as well?

The car is relatively new to me, so I don't know how old the battery was (or the glow plugs for that matter). Other threads seem to recommend getting the Duralast battery--my car probably won't last another five years--any other thoughts?

Thanks,

Alex
