This essential roadside companion needs correct charging procedures to deliver its full 700-amp power when your vehicle won’t start. Most users don’t realize their brand-new jump starter arrives partially discharged and requires that critical first charge before it can reliably revive your car’s dead battery.
Whether you’re preparing for winter emergencies or maintaining your trusty jump starter after previous use, following the right charging techniques ensures years of reliable service. This guide covers every charging scenario you’ll encounter—from initial setup to troubleshooting common issues—so you never get stranded with a depleted device when you need it most.
Find Your EverStart MAXX 700A Charging Port
Your EverStart MAXX 700A features a dedicated charging port clearly marked with a battery icon or “IN” label to prevent confusion with the jumper cable terminals. The port sits on either the side or rear panel depending on your specific model version. Modern units typically use USB-C while older models may have micro-USB—check your device before connecting cables.
Critical port identification tips:
– Never connect the charging cable to the jump-start terminals
– The charging port is significantly smaller than the battery clamps
– Look for the “IN” marking next to the port
– If you’re unsure, consult your model’s user manual
Connecting to the wrong port won’t just fail to charge your device—it could potentially damage the internal circuitry. Take 10 seconds to verify you’re using the correct port before plugging in.
Complete Your First EverStart MAXX 700A Charge Properly
Your new EverStart MAXX 700A requires a full 4-5 hour initial charge before first use, even if it shows some charge. Connect the included cable to your wall adapter (2.4-amp minimum recommended) for fastest results. Computer USB ports will work but extend charging time to 6-8 hours due to lower power output.
First charge checklist:
1. Connect the correct cable to the charging port
2. Plug into a wall adapter—not your car’s USB port
3. Verify the LED indicators activate immediately
4. Allow full charging time without interruption
5. Disconnect promptly when solid green appears
Skipping this initial charge or cutting it short risks reduced performance when you need emergency starting power most. Many users mistakenly think the partial charge is sufficient, only to discover their jump starter lacks full power during a real emergency.
Read EverStart MAXX 700A LED Charging Signals Correctly
The LED system provides instant feedback about your charging status, but many users misinterpret the signals. During charging, red LEDs fill progressively left to right as power increases. A solid green light means you’ve reached 100% capacity and can safely disconnect. Flashing red indicates serious issues requiring immediate attention.
LED troubleshooting guide:
– Steady red: Charging normally
– Filling red bars: Charge level increasing
– Solid green: Fully charged (4-5 hours typical)
– Flashing red: Overheating or connection problem
– No lights: Completely depleted battery or fault
If you see flashing red, unplug immediately and let the unit cool for 30 minutes before attempting to charge again. Persistent flashing indicates a hardware issue requiring service.
Create the Perfect Charging Environment for Your Jump Starter
Temperature dramatically impacts charging efficiency and battery longevity. Charge your EverStart MAXX 700A between 50-80°F (10-27°C) for optimal results. Below freezing, the battery’s chemical reactions slow significantly, while temperatures above 85°F trigger protection circuits that throttle charging speed.
Environmental best practices:
– Charge indoors away from direct sunlight
– Never charge in a hot car during summer
– Avoid placing near heaters or radiators
– Don’t charge immediately after bringing from cold outside
– Check device temperature every 30 minutes during charging
Charging in extreme temperatures won’t just slow the process—it can permanently reduce your battery’s capacity over time. If your device feels warm to the touch during charging, unplug it and let it cool before continuing.
Maintain Your EverStart MAXX 700A Battery Health Long-Term
Lithium-ion batteries self-discharge even when not in use, dropping to dangerous levels within 3-4 months. Recharge your jump starter quarterly to prevent deep discharge that permanently damages the battery. In extreme climates, increase this to every 2-3 months.
Critical maintenance schedule:
– Regular use: Recharge every 3 months
– Extreme temperatures: Every 2 months
– After any use: Recharge within 24 hours
– Before seasonal storage: Always top off charge
Never store your EverStart MAXX 700A completely depleted—this is the single most common cause of premature battery failure. Set phone reminders to check your device’s charge level regularly.
Charge Your Jump Starter While Driving Safely
The EverStart MAXX 700A supports pass-through charging through your vehicle’s 12V outlet—a lifesaver during road trips when you need immediate power. For best results, keep your engine running as this provides sufficient amperage for effective charging. With the engine off, charging becomes extremely slow and may not complete.
Car charging optimization:
– Use only when engine is running for fastest results
– Verify your car charger delivers at least 2 amps
– Monitor device temperature closely
– Disconnect immediately when fully charged
– Never leave charging unattended for extended periods
This feature lets you prepare your jump starter while driving to your destination, ensuring it’s ready if you encounter trouble later.
Fix Common EverStart MAXX 700A Charging Problems
When your jump starter won’t charge, systematic troubleshooting beats panic. Start with the simplest solutions before assuming battery failure. Most charging issues stem from easily fixable problems rather than internal damage.
Step-by-step troubleshooting:
1. Test your charging cable with another device
2. Try a different wall adapter (2.4A minimum)
3. Clean port with compressed air—lint commonly blocks connections
4. Check for bent pins in the charging port
5. Attempt a 15-minute “reset” charge with known-good equipment
If problems persist, contact Walmart’s warranty service—most issues within the warranty period qualify for replacement. Never attempt to open or repair the unit yourself—this voids the warranty and creates safety hazards.
Store Your EverStart MAXX 700A with Proper Charge Level
Before storing your jump starter for 6+ months, charge it to 80%—not 100%. Full charge stresses lithium-ion batteries during long storage, while 80% represents the optimal balance for longevity. Mark the storage date visibly and set calendar reminders for quarterly check-ins.
Storage protocol checklist:
– Charge to 80% (3-4 LED indicators)
– Store in original case if available
– Keep in cool, dry location away from temperature extremes
– Check charge level every 3 months
– Recharge to 80% if below 50%
This approach preserves battery health significantly better than storing at full or empty charge.
