Kia Optima Hybrid battery replacement
Kia Optima Hybrid battery diagnosis and replacement across the Phoenix metro. For 2011–2014 cars, Kia's own bulletin groups P1B70, P1B74 and P1B96 as a high-voltage battery sensor circuit fault — worth checking before any pack is bought.

Check the Kia bulletin before buying a pack
P1B96 reports that the high-voltage battery has degraded past its allowed limit. Kia's bulletin for the 2011–2014 Optima Hybrid groups it with two sensor-circuit codes, which means the sensing circuit can set it instead of the cells. That check is the difference between a wiring repair and a new lithium pack.
The question to ask your shop
"Has the applicable Kia bulletin and the battery management software update been checked for my model year?" If the answer is no, the car has not been diagnosed yet.
