Battery Information

The Altima Hybrid utilizes two batteries in order to supply both low and high voltage.

Low Voltage Battery

The Altima Hybrid contains a lead-acid 12 volt DC low voltage
battery. The low voltage battery is located in the passenger rear
quarter panel well of the trunk and is concealed by a trim cover.
The negative (-) 12 volt battery cable can be accessed through
an access panel in the trim cover.

The 12 volt battery powers the vehicle’s 12 volt electrical
system, similar to a conventional vehicle. As with conventional
vehicles, the 12 volt battery is grounded to the metal chassis of
the vehicle. However, the 12 volt battery is charged by the high
voltage battery through the DC/DC converter.

High Voltage Battery


The Altima Hybrid contains a Ni-MH 245 volt DC high voltage
battery. The high voltage battery is enclosed in a metal case,
which is isolated from high voltage, and is securely mounted in
the trunk area behind the rear seat and is concealed by a trim
cover. The service disconnect can be accessed through an
access panel in the trim cover.

The 245 volt battery powers the vehicle’s high voltage electrical
system. The high voltage battery consists of 34 low voltage (7.2
volt) Ni-MH battery modules connected in series to produce
approximately 245 volts DC. Each Ni-MH battery module is
sealed in a non-spillable plastic case. The electrolyte used in t
Ni-MH battery module is an alkaline mixture of potassium
and sodium hydroxide. The electrolyte is abso
into the battery cell plates and forms a gel that should not normally leak, even in a collision. In the unlikely
event that the high voltage battery is overcharged, the modules vent gases directly outside the vehicle through
a vent hose.

The high voltage battery supplies power to the following:
• Power cables
• EPS DC/DC converter
• DC/DC converter
• Inverter unit
• Transaxle
• Electric air conditioning compressor
