With everything safely connected, it’s time to initiate the charging process. Understanding the various modes and what to expect will ensure you get the most out of your Everstart Maxx 50 Amp Battery Charger and prolong your battery’s life.
Don’t just set it and forget it; monitor the process for optimal results.
Selecting the Correct Charging Mode
Your Everstart Maxx charger is smart, but it needs your input. Choose the mode that matches your battery and its current state.
- Battery Type: Select the correct battery type (Standard, AGM, Deep Cycle) using the charger’s selector button. This tells the charger the optimal charging profile for your specific battery chemistry.
-
Amperage Setting:
- For a standard recharge of a moderately discharged battery, select the 10A setting. This is the most common choice.
- For maintaining a charged battery over time, choose the 2A (trickle) setting.
- If your battery is completely dead and you need to start your engine immediately, select the 50A Engine Start mode. Remember, this is a boost, not a full charge.
Incorrect settings can lead to undercharging, overcharging, or even damage to the battery.
Monitoring the Charging Progress
While the charger does most of the work, observing its display and the battery’s behavior is important.
- Digital Display: The Everstart Maxx’s digital display will typically show the battery voltage, charge percentage, or “CHARGING” status. As the battery charges, the voltage will slowly rise.
- “FULL” or “MAINTAINING”: Once the battery is fully charged, the display will usually indicate “FULL” or switch to a “MAINTAINING” mode, where it delivers a small current to keep the battery topped off.
- Charging Time: Charging time varies widely based on the battery’s size, its state of discharge, and the amperage setting. A deeply discharged car battery on 10A might take 4-8 hours. A motorcycle battery on 2A could take longer.
- Temperature: While charging, the battery and charger might get slightly warm. Excessive heat or boiling sounds from the battery (if it’s a traditional flooded cell) are signs of a problem. Disconnect immediately if this occurs.
Patience is key. A slow, steady charge is generally better for battery health than a rapid one.
Disconnecting the Charger Safely
Just as important as connecting correctly is disconnecting safely. Always reverse the connection order.
- Unplug from Outlet: First, unplug the Everstart Maxx 50 Amp Battery Charger’s AC power cord from the wall outlet. This prevents any live current from flowing through the clamps.

The Everstart Maxx 50 Amp Battery Charger isn’t just for simple recharges. Many models include advanced features that can address specific battery issues or offer more specialized functions. Understanding these can save you money and extend battery life.
These specialized modes are often where the “pro” insights come into play.
Engine Start Function (50A Boost)
This is the big gun, designed for when you absolutely need to get your engine turning over but your battery is completely flat. It’s not a charging mode in the traditional sense.
To use the 50A Engine Start function:
- Connect the charger to the battery and power outlet as described in the “Setting Up” section.
- Select the 50A Engine Start mode.
- Allow the charger to run for 90 seconds to 2 minutes, building up a quick surface charge.
- Attempt to start your vehicle. If it starts, immediately disconnect the charger following the safe disconnection steps.
- If it doesn’t start, wait a few minutes, then repeat the 90-second boost and try again. Do not crank the engine for extended periods.
The 50A boost is a short-term solution. After starting, drive your vehicle for at least 20-30 minutes to allow the alternator to recharge the battery fully, or switch to the 10A charge mode for a complete recharge.
Battery Reconditioning/Desulfation Mode
Some Everstart Maxx models include a reconditioning or desulfation mode. This feature uses a specific pulse charge to break down lead-sulfate crystals that can build up on battery plates over time, reducing capacity and starting power.
This mode is particularly useful for:
- Older batteries that seem to hold less charge.
- Batteries that have been deeply discharged and left for extended periods.
- Deep-cycle batteries used in off-road setups or RVs, which often experience deeper discharge cycles.
Consult your manual for specific instructions on activating and using this mode, as it can be a longer process. It’s not a guaranteed fix for all dead batteries, but it can significantly extend the life of a sulfated battery.
Charging Different Battery Types (AGM, Deep Cycle)
The Everstart Maxx’s ability to select battery types is crucial. AGM (Absorbed Glass Mat) and Deep Cycle batteries have different charging voltage requirements than standard flooded lead-acid batteries.
- AGM Batteries: These are common in modern vehicles and off-road setups due to their vibration resistance and sealed nature. They require a slightly lower charging voltage than flooded batteries.
- Deep Cycle Batteries: Designed for sustained power delivery over long periods (like for winches, camping fridges, or auxiliary power systems), they tolerate deeper discharges. They also benefit from specific charging profiles to maximize their lifespan.
Always ensure you select the correct battery type on your charger. This prevents overcharging AGM batteries and ensures deep cycle batteries get the thorough charge they need for optimal performance in demanding scenarios like off-grid camping.
Troubleshooting Common Issues with Your Battery Charger
Even with the best equipment, sometimes things don’t go as planned. Knowing how to troubleshoot common problems can save you time and frustration, getting you back on track quickly.
Many issues are simple fixes, but some indicate a more serious underlying problem.

If your charger isn’t responding or is showing a cryptic error code, here are some things to check:
- Power Source: Is the charger properly plugged into a live AC outlet? Test the outlet with another appliance.
- Circuit Breaker: Has the circuit breaker on your wall outlet or the charger itself (some have internal breakers) tripped?
- Faulty Connection: Are the battery clamps making good, clean contact with the battery terminals (or chassis ground)? Loose or corroded connections are a common culprit.
- Reverse Polarity: If the clamps are connected backward (red to negative, black to positive), most modern Everstart Maxx chargers have reverse polarity protection and will not operate or will display an error. Disconnect and reconnect correctly.
- Battery Fault: If the battery is severely damaged or has an internal short, the charger might refuse to charge it to prevent further issues.
Consult your Everstart Maxx manual for a list of specific error codes and their meanings.
Battery Not Charging or Taking a Charge
You’ve connected everything, but the battery voltage isn’t rising, or the charger isn’t indicating a charge:
- Sulfation: If a battery has been dead for a very long time, it might be heavily sulfated, preventing it from accepting a charge. Try the reconditioning mode if your charger has it.
- Dead Cell: A battery with a completely dead cell cannot be revived by a charger. This often manifests as the battery showing a very low voltage (e.g., under 10V for a 12V battery) that won’t increase, or the charger indicating a fault.
- Incorrect Settings: Double-check that you’ve selected the correct battery type and amperage setting on the charger.
- Charger Malfunction: In rare cases, the charger itself might be faulty. If you’ve ruled out all other possibilities, consider having the charger tested or replaced.
If your battery consistently refuses to charge, it might be time for a replacement. A professional battery test at an auto parts store can confirm its health.
Overheating or Unusual Smells
Any signs of overheating, smoke, or unusual smells (like rotten eggs, indicating hydrogen sulfide gas) from the battery or charger are serious warning signs.
- Immediately Disconnect: Unplug the charger from the wall outlet first, then carefully remove the clamps.
- Battery Damage: Overheating can indicate an internal short in the battery or severe overcharging.
- Charger Fault: Excessive heat from the charger itself could mean an internal component failure.
- Ventilation: Ensure you are in a very well-ventilated area, as these smells can indicate dangerous gas buildup.
Do not attempt to continue charging if you notice these signs. A damaged battery can be extremely dangerous and should be replaced. A faulty charger should be serviced or replaced.
Maintaining Your Charger and Batteries for Longevity
Proper maintenance extends the life of both your Everstart Maxx 50 Amp Battery Charger and the batteries it serves. A little care goes a long way in ensuring your gear is ready when you need it most, whether for an emergency start or keeping your off-road accessories powered.

- Cable Management: Coil the power cord and battery cables neatly. Avoid kinks or sharp bends that can damage the internal wiring.
- Storage: Store the charger in a cool, dry place, away from extreme temperatures, moisture, and corrosive chemicals. A garage shelf or toolbox is ideal.
- Inspection: Periodically inspect the charger’s casing, cables, and clamps for any signs of damage, fraying, or wear. Replace if damaged.
A well-maintained charger is a reliable charger.
Battery Health Best Practices
Your charger is only as good as the battery it’s connected to. Implementing these practices will help your batteries last longer.
- Keep Terminals Clean: Regularly check and clean battery terminals to prevent corrosion, which inhibits charging and starting power.
- Check Fluid Levels (Flooded Batteries): For traditional flooded lead-acid batteries, check the electrolyte levels periodically. If low, top up with distilled water (never tap water or acid). AGM and sealed batteries do not require this.
- Avoid Deep Discharges: Try not to let your batteries go completely dead. Repeated deep discharges significantly shorten battery lifespan. Recharge them as soon as possible after use.
- Regular Charging: If a vehicle or battery will be stored for an extended period (e.g., an RV over winter, a motorcycle), connect it to a 2A maintenance charge using your Everstart Maxx charger. This prevents self-discharge and sulfation.
- Temperature Management: Extreme heat or cold can degrade batteries. If possible, store batteries in a moderate temperature range.
By taking care of your batteries, you ensure they’re always ready to power your adventures, from the daily commute to the most demanding off-road excursions.
Frequently Asked Questions About Everstart Maxx Battery Chargers
Here are some common questions we hear about using battery chargers, especially powerful units like the Everstart Maxx 50 Amp model.
Can I leave my Everstart Maxx 50 Amp Battery Charger connected indefinitely?
Most modern Everstart Maxx chargers feature an automatic “float” or “maintenance” mode. Once the battery is fully charged, the charger will switch to delivering a very low current to maintain the charge without overcharging. While generally safe for extended periods, it’s always best to check your specific model’s manual for confirmation. For true long-term storage, a dedicated trickle charger or battery maintainer might be a better option if your Maxx charger doesn’t explicitly state it’s safe for indefinite connection.
What’s the difference between a battery charger and a jump starter?
A battery charger, like the Everstart Maxx 50 Amp, slowly recharges a discharged battery over several hours. It provides a steady, controlled current. A jump starter, on the other hand, provides a very high burst of current (often hundreds of amps) for a few seconds to immediately crank a dead engine. While the Everstart Maxx has an “Engine Start” (50A) mode, it’s more of a powerful boost than an instant jump start, requiring a minute or two to deliver enough charge to the battery to help it turn over.
Can I charge a completely dead battery with this charger?
Yes, the Everstart Maxx 50 Amp Battery Charger is capable of charging deeply discharged batteries. However, if a battery is completely dead (below 10V for a 12V battery) or has an internal fault like a dead cell, some smart chargers might refuse to initiate a charge for safety reasons. In such cases, the battery may need to be replaced. If it does accept a charge, use the 10A setting for a slow, thorough recharge.
How do I know if my battery is truly charged?
Your Everstart Maxx charger’s digital display will typically indicate “FULL,” “100%,” or switch to a “MAINTAINING” status when the battery is fully charged. You can also confirm with a multimeter by checking the battery voltage after it has rested for an hour or so off the charger; a fully charged 12V lead-acid battery should read around 12.6V to 12.8V.
Is it safe to charge my battery in freezing temperatures?
Charging a battery in freezing temperatures is generally not recommended, especially if the battery is deeply discharged. A discharged battery can freeze, and attempting to charge a frozen battery can cause it to rupture. If you must charge in cold weather, bring the battery indoors to a warmer temperature first, or ensure it’s at least above freezing. Always follow the manufacturer’s guidelines for temperature ranges.
