Replacement battery connexions for Sony DVP-FX730

The original battery was thrown out by mistake which had the 3 way male adapter. An article states that you can use two 3.7V batteries. The connection to the original battery has 3 wires, red, white and black.

Can you explain how the 3 wires should connect to the two 3.7V batteries?

Hi,

The battery shown at Step 6 in the Ifixit battery replacement guide for the player here. shows that the original battery was a Sony 890203401-815-G with a part number of 9 885 129 95.

Searching online using just these numbers brings results for a 7.4V 3200mAH 23.68Wh battery. They are very expensive.

With regards to your 2 x 3.7V batteries. They would have to be connected in series to give the 7.4V required, The white wire would have to be connected to some kind of thermal sensor to monitor the battery temperature.

@mcmonocle your connector calls for positive, ground and thermal sensor from the battery. Most likely to prevent overcharging. So you have to come up with a way of tricking the board to think you have that connection. Or just get a battery with that sensor. Sony part number is 9-885-129-95 for the battery
