Electric vehicles (EVs) have transformed the way we travel, offering eco-friendly and cost-effective alternatives to gas-powered cars. Whether you use your EV for daily commutes or long road trips, keeping it charged is crucial. Without a reliable charging solution, you could find yourself stranded or limited in travel options.
Thankfully, Battery Tender® offers high-quality EV charging solutions designed for both home use and on-the-go charging. This guide explores the best EV chargers, their features, and how to ensure your EV’s battery, both 12V auxiliary and high-voltage lithium-ion, remains in peak condition.
Why Choosing the Right EV Charger Matters
Unlike traditional gas stations, charging your EV requires planning. The charger you use impacts your vehicle’s battery health, charge time, and overall convenience.
Battery Tender specializes in home and portable EV charging solutions, ensuring that no matter where you are, you have a reliable power source. But before diving into our top picks, let’s clarify a common misconception: jump-starting an EV.
Can You Jump-Start an EV?
Many people assume that when an EV “dies,” it simply needs a jump-start. However, this is only true for the 12V auxiliary battery, not the high-voltage lithium-ion battery that powers the motor.
- The 12V battery powers essential electronics such as lights, dashboard displays, and sensors. If it dies, your EV may not turn on, even if the high-voltage battery is fully charged. Fortunately, a 12V battery can be jump-started just like in a traditional car.
- The high-voltage battery, however, cannot be jump-started. Instead, it requires proper charging through an EV charger.
Be sure to consult your EV’s manual, as some vehicles have unique steps or access points for jump-starting the 12V battery.
Battery Tender provides advanced EV charging solutions to keep your vehicle powered and avoid such issues. Let’s explore the best options for your needs.

Understanding EV Battery Systems: 12V vs. High-Voltage
EVs contain two distinct battery systems that serve different purposes:
- 12V Auxiliary Battery: Powers electronics such as dashboard displays, infotainment, and lighting.
- High-Voltage Lithium-Ion Battery: Provides energy for the motor and vehicle propulsion.
Each battery has unique issues and requires specific solutions.
12V Battery Issues in EVs
The 12V battery in an EV functions similarly to that in traditional gas-powered cars. However, it doesn’t recharge via an alternator; instead, it receives power from the high-voltage system. Common issues include:
- Discharge from inactivity – If an EV sits unused for long periods, the 12V battery may drain.
- Cold weather impact – Extreme temperatures can reduce battery capacity.
- Aging and degradation – Over time, 12V lead-acid batteries wear out and may require replacement.
- Failure to start – If the 12V battery dies, the vehicle won’t turn on, even if the high-voltage battery is fully charged.
High-Voltage Battery Issues in EVs
The high-voltage lithium-ion battery is the primary energy source for an EV. Like any battery, it can experience issues such as:
- Reduced driving range – Over time, battery degradation leads to decreased mileage per charge.
- Thermal management problems – Poor cooling can result in overheating and efficiency loss.
- Charging difficulties – Faulty charging cables, ports, or a malfunctioning battery management system (BMS) can cause issues.
- Cell imbalance – Uneven wear on individual battery cells affects performance.
