Hybrid Vehicle (HV) Battery Pack and Auxiliary Battery

The LS600h/LS600hL features a high voltage Hybrid Vehicle (HV) battery pack that contains
sealed Nickel Metal Hydride (NiMH) battery modules.

HV Battery Pack

N
The HV battery pack is enclosed in a metal case and is securely mounted in the trunk area
behind the rear seat. The metal case is isolated from high voltage and concealed by fabric
covers.
N
The HV battery pack consists of 20 low voltage (14.4 Volt) NiMH battery modules
connected in series to produce approximately 288 Volts. Each NiMH battery module is
non-spillable and sealed in a metal case.
N
The electrolyte used in the NiMH battery modules is an alkaline mixture of potassium and
sodium hydroxide. The electrolyte is absorbed into the battery cell plates and will not
normally leak, even in a collision.
N
In the unlikely event that the battery pack is overcharged, the modules vent gases directly
outside the vehicle through a vent hose.
