Charge, maintain, and desulfate your vehicle or RV battery without ever touching the terminals. The BatteryMINDer 1500-OBD2 plugs directly into your vehicle's OBD2 diagnostic port, delivering a safe 1.5-amp charge and full-time high-frequency pulse desulfation to extend battery life -- no hood access, no terminal clamps required.
Every vehicle built after 1996 is required by law to have an OBD2 port, and the BatteryMINDer 1500-OBD2 takes full advantage of it. Using the included SAE-to-OBD2 connector, this compact wall-outlet charger routes 12 volts directly to your battery through the vehicle's existing wiring -- no need to pop the hood or locate battery terminals buried under plastic covers.
Beyond simple maintenance charging, the 1500-OBD2 runs continuous high-frequency pulse desulfation, targeting the lead-sulfate buildup that kills batteries prematurely. BatteryMINDer claims up to 4x battery life extension with regular use, and the unit can recover batteries that have dropped as low as 3 volts -- a threshold many conventional chargers refuse to work with.
Connects via the factory OBD2 port. No hood, no clamps, no searching for buried terminals.
Runs full-time pulse desulfation -- high frequency, not high voltage -- to dissolve sulfate buildup and restore capacity.
Built-in ambient temperature sensor (pre-installed) adjusts charge rate from -4F to 122F for safe year-round operation.
Maintain up to 4 batteries simultaneously with optional Y-Connectors (210AY, sold separately).
This charger is purpose-built for vehicles and RVs that sit unused for extended periods -- tow vehicles parked between trips, motorhomes in storage, or any vehicle where the battery is difficult to access. It is particularly useful for late-model trucks and SUVs where the battery is mounted under the seat, in a rear compartment, or behind trim panels.
BatteryMINDer's patented high-frequency pulse desulfation actively works against the leading cause of battery failure. Unlike simple float chargers, the 1500-OBD2 treats and conditions the battery while it maintains charge level.
Many chargers refuse to engage a deeply discharged battery, leaving you no option but a jump start or replacement. The 1500-OBD2 is designed to recognize and begin charging batteries at voltages as low as 3 volts DC, making it a genuine recovery tool -- not just a float maintainer. This is especially valuable for batteries that have self-discharged during long storage periods.
The OBD2 port on most vehicles is connected directly to the vehicle battery and provides unswitched 12V power. This allows the 1500-OBD2 to charge and maintain the battery regardless of ignition position. Check your vehicle's OBD2 port wiring if you are unsure -- a small number of vehicles wire the OBD2 port through a switched circuit, which would limit charging to key-on operation only.
The 1500-OBD2 can maintain up to four batteries at once when paired with BatteryMINDer SmarTECHnology Y-Connectors (part number 210AY, sold separately). This makes it a practical solution for rigs with both chassis and house batteries, or for shop use where several vehicles need periodic maintenance charging.
Add the SmarTECHnology Multiple Battery Connector (part 210AY, sold separately) to expand this charger to maintain up to 4 batteries simultaneously from a single unit.
For best results, connect the 1500-OBD2 at least once per month during storage periods. Leave it plugged in for at least 24-48 hours on a deeply discharged battery before expecting a full recovery charge. The unit is designed for unattended long-term use -- the temperature sensor and automatic charge management handle the rest.
