reComputer J202 GPIO (TXB0108) and rechargeable RTC

We are looking at using the reComputer J202 carrier board in one of our products. However, having used the NVIDIA dev kit previously we have had very random problems with the GPIO because of the TXB0108 8-Bit Voltage-Level Translator all we want to to be able to set a pin high or low, the NVIDIA forum is littered with developers having the same problem! Does the reComputer J202 use the same transceiver?

Secondly, our customer is asking how long the RTC battery will last and if it is possible to recharge it?

Looking forward to the discussion
