Battery for toy drone

Hi,

I have a confession to make. The charger is coloured black but has a white integral insert (which takes the battery terminal connector). In my stupidity, I thought the insert was part of the battery terminal connector and had got stuck, so tried to prise it out, thereby completely naffing it.

So, the battery itself is fine, I just need a new charger. Unfortunately, your link for the charger is not accessible. Here are a couple of photos of battery and terminal connector. I have looked at loads of chargers on Ebay, but am still unsure as to the right charger. (The drone in question doesn’t seem to have ever been very popular). Grateful for your advice and hope photos narrow it down.
