you mean you need a circuit diagram for the following APC unit? i dont think so if you can get unless theres one MF from APC manufacturing or service center that can give it or sell it to you. beacuse as far as i am concerned it is punishable by law to sell or to give copy of all circuit diagram of APC products. Good luck

Solution #1 is absolutly correct.......
But...keep something in mind. You also have a 50-50 chance that the inverter may have also gone...with the battery. So you could buy a new battery for $30.00 or you could by a new UPS for $65.00
So does this APC you have seem almost disposable?
The question is....if you buy a $30.00 battery and the unit does not work, then you buy a $65.00 UPS, how much did it actually cost you? Just consider that option.

I Bought two RBC32's and had to hook them up to the connector and did it wrong on the first try. Make sure you connect the yellow to the Red terminal on one battery and the Black on the other, then connet the remaining red to red on one and black to black to the other. Once I did that and plugged it back in everything worked fine.
