A123's robust 12V battery can accept high rates of charge and capture several times more energy from regenerative braking for improved vehicle fuel economy and reduced emissions. This advantage is sustained over product life and does not suffer the severe performance degradation experienced with lead-acid technologies.
A123’s breakthrough Lithium-ion chemistry now delivers a wider temperature operating range for exceptional cold crank performance that outperforms lead acid and also contributes to system reliability.
A123’s UltraPhosphate delivers a solution that widely performs for the life of the vehicle. Long life and high durability in start-stop applications defer the need to replace the 12V Starter Battery, which improves vehicle manufacturers warranty risk and total cost of ownership for the consumer.

Battery pack has something wrong with circuitry, not cells.
BMS, Relay, Fuse, or Voltage Sense Harness could have a problem.
Main posts on top might not have voltage due to the BMS disabling the contactor due to issue above.
Battery cells will have voltage and be in good working order.
