Dead Battery, We Arrive in 15-25 Minutes
You turned the key and got nothing. A weak click. Total silence. Dark dashboard. San Diego's dry heat burns batteries faster than most climates, a battery rated for five years might last three here. We arrive with a commercial surge-protected jump box, start your vehicle, and test your battery and alternator before we leave.
Servicio en Tijuana: (664) 801-9382Call (619) 872-5285, we arrive in 15-25 minutes with a professional surge-protected jump box, start your car, and test your battery and alternator before we leave. Flat rate. EV and hybrid 12V systems included. 24/7/365, fully bilingual English and Spanish.
A jumpstart sounds simple, connect cables, start the car, done. But a professional jump is more involved than what your neighbor does with a pair of cables from the trunk, and the difference matters for your vehicle's health.
Consumer jumper cables create a direct electrical bridge between two vehicles. If the donor battery surges or the connection sparks, you risk frying sensitive electronics, infotainment, body control module, or ECU. Our commercial jump boxes have built-in surge protection and voltage regulation. This is especially important on vehicles manufactured after 2015.
Before we connect anything, we check your battery terminals for corrosion, loose connections, and physical damage. Corroded terminals are a common reason a battery "dies" even when the battery itself is fine. If corrosion is the issue, we clean the terminals on the spot.
After starting your vehicle, we connect a diagnostic tool that reads cold cranking amps (CCA) and alternator output voltage. A healthy battery reads close to its rated CCA. A healthy alternator puts out 13.5-14.5 volts at idle. If your battery reads below 60%, it is on its way out. If your alternator reads below 13 volts, it is not charging the battery.
Drive your vehicle for at least 20 minutes without stopping. Highway driving is best, higher RPMs charge the battery faster. Avoid short trips for the rest of the day. If the battery tested weak, drive directly to an auto parts store (AutoZone, O'Reilly, NAPA) for a bench test and possible replacement.
We would rather you save the call and the money if the fix is something you can do yourself in 30 seconds.
1. Check if your headlights or dome lights work. Turn on the headlights. If they are bright, your battery probably is not the problem, it might be a bad starter motor, a failed ignition switch, or a neutral safety switch issue (try shifting to neutral and back to park, then turning the key).
2. Check the battery terminal connections. Pop the hood. If you see white or green crusty buildup on the terminals, that corrosion might be blocking the connection. If you have a wrench, try loosening and retightening the terminal clamps.
3. Try a different key or fob. If you have a push-button start vehicle and the car will not respond, your key fob battery might be dead, not the car battery. Most push-button cars have a backup: hold the fob against the start button and press. Tesla Model 3 and Model Y owners can use the Tesla app to start the car even with a dead fob.
Every hybrid and EV has a standard 12V battery that powers accessory systems. When it dies, the car appears completely dead even though the main traction battery is fully charged.
When the 12V dies on a Tesla, Prius, or Leaf, the car cannot wake up and you cannot access the main battery's power. This catches owners off guard. We know the access procedures and use the correct jump protocols to avoid triggering fault codes.
Important: Jumping an EV or hybrid incorrectly can trigger high-voltage safety disconnects and throw expensive fault codes. Our technicians are trained on manufacturer-specific procedures for each vehicle.
You came home Friday, left something plugged into the 12V outlet, and now it is Monday at 7:15 AM and the car is dead. You need to be in Sorrento Valley by 8.
Call (619) 872-5285, if you are in central San Diego, we are there in 10-15 minutes. You can still make it to work.
San Diego International's economy lot and the off-site lots on Pacific Highway are dead-battery hotspots. A slow parasitic drain, alarm system, GPS tracker, dashcam on parking mode, killed the battery over a week.
We are 10 minutes from the airport.
El Cajon, Santee, Lakeside, and Alpine regularly hit 100+ degrees in July and August. That heat cooks battery fluid and warps internal plates.
If your battery is more than two years old and you are in East County, a summer failure is not a matter of if but when. We respond in 18-25 minutes.
You parked on J Street for dinner, left headlights on manual, and came back three hours later to a dead car. It is 11 PM and you need to get home to Scripps Ranch.
Downtown is our fastest response zone, 10-15 minutes.
The 12V in your Tesla, Prius, or Leaf dies and the car appears completely dead. We know how to access and jump the 12V systems on these vehicles, including Teslas where the 12V is behind a panel requiring specific steps when the car is powered down.
The classic. You unloaded groceries from Costco, left a door slightly ajar, and the dome light drained the battery overnight. 6:30 AM, kids need to get to school.
We are 15 minutes away.

If your battery died while idling in traffic and you are on the I-5 or I-8 shoulder, stay in the car with hazards flashing. Do not open the hood on a freeway shoulder in San Diego, shoulders are narrow, traffic is fast, drivers are distracted. Let our technician handle it.
Downtown San Diego parking structures at Horton Plaza, Seaport Village, and the Convention Center have poor ventilation. Batteries can emit hydrogen gas, especially when deeply discharged. Do not attempt a jump in an enclosed garage without proper ventilation.
If your car died in direct sun on a 95-degree day in El Cajon or Santee, do not sit in the car with windows up. Roll them down or stand in shade nearby. Interior temperatures can reach 140 degrees in San Diego summer.
If you see cracks in the battery case, swelling, or any liquid leaking, do not attempt a jump, self-serve or professional. A damaged battery can release hydrogen gas or acid.
Most common mistake: the jump works, you drive two blocks to the gas station, turn off the car, and it is dead again. The alternator needs sustained running time to replenish the charge. Drive on the freeway or a long surface street, Pacific Highway, Friars Road, El Cajon Boulevard.
RJ Towing charges a flat rate of $75 for a standard jumpstart, any vehicle type, any location in the county, any time of day. That includes the jump itself, battery terminal inspection, and a post-jump battery and alternator test. No trip fee, no surcharge for nights or weekends.
Average response across San Diego is 15-25 minutes. Downtown and Mission Valley calls are typically 10-15 minutes. South Bay averages 12-18 minutes. East County runs 18-25 minutes. We tell you the real ETA on the phone.
If the battery will not accept a charge at all, it is past the point of jumping. Our technician confirms with a load tester and gives you two options: we tow your vehicle to an auto parts store or mechanic where the battery can be replaced, or you have a replacement brought to your location. We quote the tow price before we load.
Yes. RJ Towing technicians are trained on 12V auxiliary battery jumps for Teslas (Model 3, Y, S, X), Prius, Nissan Leaf, Chevy Bolt, Ford Mach-E, and other hybrids and EVs. We know the access procedures, including Tesla's manual frunk release, and use the correct jump protocols to avoid triggering fault codes.
After jumping your car, we test both. A battery below 60% of rated CCA is failing, another dead battery is coming soon. An alternator below 13 volts at idle is not charging. Our technician tells you which is the problem and recommends next steps. If both test good, something drained the battery overnight, a light, a dashcam, or a failing door switch.
Drive for at least 20 minutes continuously. Freeway driving is ideal because higher RPMs charge the battery faster. Avoid short trips for the rest of the day. If the battery tested weak during our diagnostic, drive directly to an auto parts store for a bench test, AutoZone, O'Reilly, and NAPA all test batteries free in San Diego.
Absolutely. RJ Towing is fully bilingual. When you call (619) 872-5285, you can communicate entirely in Spanish from the first word. This is not a translation app, it is our native capability. Para arranque de batería, llame al (619) 872-5285, servicio en español las 24 horas.
Consumer jumper cables connected incorrectly, reversed polarity, voltage spikes, or sparking at the terminals, can damage your ECU, infotainment, or other electronic modules. This is why we use commercial surge-protected jump boxes with built-in voltage regulation instead of vehicle-to-vehicle cables.
