Do partial enhancive recharges cost more bounty points?

[Askip]

I believe it costs the same amount of BPs to recharge an item that has expended 1 charge, or 20 charges? So, if empty, it costs 10k BPs to charge it would cost 10K BPs to charge the same item if still decently charged up.

That seems correct, I just tested with a recently charged item and it costs the same as if empty.
