Problem: I replaced the OEM battery with a generic one from iFixit. Its individually wrapped “rainbow” wires weren’t shaped like the OEM battery’s were, preventing them from laying flat. They obstructed a case screw. I didn’t realize this until I looked to see why the screw wasn’t going in, and then saw the slightly frayed cable. Question: Is wrapping each exposed wire of the battery cable with electrical tape okay? Aside from the added bulk in a tight space. Thanks!
@vermilion_beats as long as it is just frayed, yes it is okay. Just make sure it stays well insulated from any metal, component etc.
