Will this ac adapter charge my Rival Perses battery?

I've had a perses laying around since I bought it, because it came without a charging cord I have the cable for the Rival Rechargeable battery pack, but it doesn't charge the perses battery, when I bought the perses it was fully charged so I know it works.

I've been looking for a charger that fits in local store but they don't even know that Tamiya connectors exist hahaha, I found this one on Amazon for around 17 dollars, is this the correct amperage and voltage? Or what should I look for?
