Battery packs can set a fault code if only one of the battery modules falls out of balance. Many modules from battery cores still are viable and capable of O.E. performance. Renewed battery modules are obtained from battery cores that have passed CARDONE’s very stringent set of performance tests, meet O.E. performance, and are suitable for renewal and reuse in a remanufactured Drive Motor Battery.
The hybrid or electric vehicle’s original safety or service plug can be reused with CARDONE’s replacement Drive Motor Battery. If this original plug is damaged or misplaced, CARDONE offers replacement service plugs for sale.
Always make sure the “READY” light is off on the instrument panel or multi-function display, the ignition or power button is off and the key is out of the vehicle before you begin any service or repair work. If the vehicle has a remote keyless entry system, remove the key from the vehicle and keep the keyless fob at least 20 feet away to prevent accidental starts and/or trouble codes from being set. The negative terminal at the 12-volt auxiliary battery must be disconnected and the service plug must be removed. If equipped with a service switch, the switch must be in the “off” position.
Always wear safety glasses, Class “O” linemen gloves rated @ 1,000 volts and leather outer protectors over the linemen gloves. Gloves must be certified and expiration date must be current. Always remove jewelry and use insulated hand tools. Other forms of Personal Protective Equipment such as an insulated safety hook, googles, face shield, apron, and shoes should be considered. Always follow O.E. Manufacturer’s safety procedures.
Yes, the electrical motor/generator in a hybrid electric vehicle can generate voltage when pushed with its wheels on the ground. The vehicle should be moved using dollies under the front and rear wheels.
Yes, as batteries sit in storage, the modules being to lose charge and fall out of balance. CARDONE's included stickers on both the shipping case and actual battery that clearly indicate when the battery was last charged at the factory as well as the last date it should be installed. If a battery is installed beyond the stated shelf-life period, it will likely operate normally at first, but could be prone to premature failure.
No. NEVER attempt to use external charging equipment on a high-voltage battery. This can result in serious injury, battery damage and property loss. CARDONE’s specialized equipment properly recharges and rebalances batteries that have exceeded shelf-life.
It only takes one battery module in the pack for the battery to become unbalanced or stop functioning. Additionally, internal electronic and cooling components within the battery pack can stop functioning properly, despite healthy battery modules, resulting in battery pack failure. A failed battery pack may only be a symptom of the true root cause of a problem in a hybrid or electric vehicle. Hybrid and electric vehicle powertrains are highly interdependent systems, and only a trained professional can properly diagnose a battery issue versus a poor-performing inverter or ground fault.
For most hybrid and electric vehicles you can check for battery pack related codes using a generic scanner. A factory scan tool, or equivalent, with the correct operating software will be necessary for performing diagnostic procedures, configuration and programming.
The P0A80 and the P0A70 are the most common trouble codes related to battery pack failure. When a “P0A80” is set, it means that the powertrain control module has detected a malfunction in the hybrid vehicle battery management system (HVBMS). If the battery control module determines one of the battery packs is starting to fail, the it will set code “P0A80”. When a P0A70 is set, it could indicate a poor connection at the battery pack, a problem with unbalanced modules with the battery pack or a battery pack electronic control unit (ECU) issue.
A full state-of-charge would be 80%, however, O.E. Manufacturers have designed the Drive Motor Battery Packs to operate at approximately 60% state of charge (SOC) in order to permit brake regeneration and healthy charge/ discharge cycles without overheating. CARDONE batteries are shipped ready for operation at a 50-70% SOC, depending on the intended used of the battery.
Benchtop battery module swapping relies on used modules from another source that may not be best matched to the remaining modules in the original pack. Through profile matching methods, CARDONE engineers select the best-suited battery modules from CARDONE's library to remanufacture a battery pack to match O.E. performance.
It can take up to 100 miles of driving for the vehicle to go through the necessary drive cycles in order for the MPGs to display accurately.
Yes, the 12-volt auxiliary battery can be jump-started in the same way as most conventional non-hybrid electric vehicles.
