We are testing more...
In these cases, you need a new battery...
or
Your Lithium battery no longer holds a charge
Your Lithium battery is more than 5 years old
In these cases, you may consider using a
lead-acid battery instead...
or
or
The Lithium battery is too expensive ($2200+)
Lithium batteries are out of stock
You don’t like forced consumption caused by technological monopoly
In this case, you need our modification kit!
Lead-acid battery(AGM) not compatible with your car directly
With only $459, you can get rid of the trouble of the Lithium Battery FOREVER!
The modification kit does not include any lead-acid battery.
Since the programmer can be used multiple times, calling your trusted auto repair shop
to purchase multiple sets of products from us at once will reduce your modification costs.
Our modification kit include the following items:
Battery vent connection cap
BMS pwer supply wire
Modified negative lead
OBD Programmer
01
Why should I replace the lithium battery with a lead-acid battery?
1. In many cases, lithium battery activates power-off protection and cannot recover automatically, preventing the battery from being charged. Even brand-new lithium batteries can have this problem.
2. Only dealerships can officially replace batteries, the price is usually between 2,200 and 3,000 US dollars, and they are often out of stock.
3. The manufacturer of the 2024 Porsche Cayenne model no longer uses lithium batteries and has switched back to lead-acid batteries.
4. A Lead-acid battery is a very mature and stable battery with a low price and long service life (up to 5-6 years in a car).
5. The replacement price is only 1/8 of the price of the original car's lithium battery.
6. The installation is simple and convenient, and some auto mechanic enthusiasts can even complete the replacement themselves in their home garage. It is recommended to use a 92A/95A capacity battery, which has a reserved position and can be installed in its original position without damage.
7. Retains all the functions of the original lithium battery (including start and stop functions)

How does our modification kit work?
The original vehicle lithium battery management system (BMS) is integrated inside the battery, connected to the body computer through LIN line communication, and transmits the current voltage and current data of the battery in real time.
The lead-acid battery itself does not have a BMS or similar thing. Suppose we want the lead-acid battery to be compatible with the Porsche/Lamborghini/Bentayga onboard computer. In that case, you need to install an additional BMS and overwrite its original lithium battery data.
We integrated the battery voltage monitoring manager into the newly designed negative line. Use this freshly designed line to replace the original car's power line and add an external power supply line to complete the hardware modification.
Then, to use our OBD automatic programmer overwrites the battery configuration data of the original 2024 Cayenne models to achieve compatibility and synchronization, allowing the onboard computer to continue to monitor the battery voltage and current, thereby completely realizing battery replacement.
Our OBD programmer only overwrites the battery data configuration data and does not leave any other parameters unchanged.
Our modified kit includes all the necessary parts mentioned above.

How to use this modification kit?
If you are new to auto repair work, we strongly recommend that you call your most trusted auto shop and ask them to purchase our kits to replace your battery.
Because our programmers can be reused multiple times, they are more cost-effective for auto repair shops and can save you money.
If you are an auto repair enthusiast, you can follow the instructions below:
1. Purchase a personal modification kit from us (one negative lead + single-use programmer) and purchase a regular lead-acid battery (92A/95A) at your own cost;
2. Take out the original lithium battery from your car;
3. Put the lead-acid battery into the car;
4. Connect the positive terminal of the battery to the car (use the car's original lead);
5. Connect the negative terminal of the battery to the car (use the lead from the modification kit);
6. Install the white plastic cap from the modification kit on the air tube and insert the air tube into the new battery;
7. Connect the smaller wire from the retrofit kit as shown in the picture and tighten the nut on the end marked "150";
8. Start the car. If the car starts successfully, it means that the new battery is installed successfully, and you can ignore all battery error messages at this time. If the car does not start, recheck that the battery is installed correctly;
9. Turn off the car;
10. Find the OBD interface above your left foot in the driver's seat;
11. Insert the programmer into the OBD interface and wait for about 10 seconds. If you hear a beep, the overwriting is successful. If you hear a continuous beeping sound, it means that the programmer has reached its usage limit and needs to be replaced with a new one.
