Default Bad packs?

I charged my gp3300 pack with Intellipeak pulse charger, and it has high pitch hum noise coming from the battery pack, weird... is this normal? do i have a bad pack here?

sounds like you had a vented a cell ... try to discharge it then let it sit a while .. then try to charge it ,should be good for a practice pak , but you never know .. also get a multi meter and chk the cells ... you might be able to get another cell and replace the bad one ..

Thats normal, don't worry!

its because of the high frequency pulse from the charger.

My understanding is that Ni-MH packs don't like being pulse charged supposed to be linear charge only??
