Hyno Energy. NiMH Battery Replace For Lexus RX400H (2006-2009). Standard Size, 6500mAh 288V
A key failure point of hybrid batteries is when the individual cells become unbalanced from one another. A typical 15 series LEXUS RX400H has 15 individual cells and each of these cells have a capacity of approximately 6500mah. Over time this capacity deteriorates down to as low as 1500mah. This deterioration however, is never even while some cells maybe as low as 1500mah others could be 5000mah or higher. An unbalanced hybrid battery will deteriorate faster than one that is evenly balanced.

Cautions of Battery Pack Transportation and Storage
Avoid violent vibration and external force impact, don’t cast, roll, invert, extrude, and stack too high during handling and transportation of battery pack.
Protect the battery pack from rain during the transportation, and the ambient temperature is not over 55℃.
Store the battery pack in a cool and dry place and the temperature range is 5-25℃ when you are not using it.
Maintenance regulations (Maintain the whole battery pack, and cool with a fan during the charge and discharge process)
The SOC of our battery pack is 60%~80% when leaving the factory, in long-term storage, battery should be stored in a charged state (usually the SOC is 80%). Have a charge and discharge maintenance to battery pack when the storage time is over 6 months or battery module’s voltage is 15V,to prevent the battery performance’s decline caused by the self-discharge. The maintenance regulations are as follows:
- Discharge: 2A discharge to 204V (that is to say: single cell 1.0V)
- Interval: 30 minutes
- Charge: 1.3A charge for 5 hours (voltage ≥ 306V, -ΔV ≥ 0.2V and temperature ≥50℃)
- Interval: 1hours
- Discharge: 2A discharge to 204V (that is to say: single cell 1.0V)
- Interval: 30 minutes
- Charge: 2A charge for 2.4 hours
Installation Cautions of battery pack
Notes: Installing this product should only be attempted by a qualified technician, the voltage of the battery pack is very high, which has the shock hazards, so when installing the battery pack, you should wear insulating gloves and use insulated handle tools.
- Please operate according to assembly manual during the installation of Prius battery pack.
- Do not mix our battery modules with those of other manufacturers, or new battery modules in use with semi-used battery modules, and don’t mix battery modules within a battery pack with those in other battery pack.
- Don’t twist and bend battery modules and accessories when assembling battery pack.
- Don’t connect the anode and cathode of battery module in reverse when assembling battery pack, to prevent short circuits.
- Fasten bolts and nuts with appropriate torque, avoid loose connection or damaging other accessories with too big torque.
