Surface Pro 5 Pro 6 Battery

I asked for a battery for my Surface Pro 5 1796, but they sent two. It's new, so it would be a waste to send it back. I think it's also compatible with the 6. Negotiable. Extra information: Model: EDA00.3436.907 (without period, OLX penalizes if it's a phone number) 45Wh 5940mAh
