One of the most popular batteries on the market today is lithium batteries. They are quite reliable for many applications, such as electric vehicles, solar panels, backup power, and other pieces of equipment. Even today, they require a reliable charger to ensure they stay operational for the long term. In this guide, we will look at some of the best 24V lithium battery chargers for sale.
In addition, we’ll discuss what makes lithium batteries advantageous compared to other types, like lead-acid batteries. We’ll also suggest some key features to look for whenever you decide on a battery charger that fits your needs and preferences.
Why Use 24V Lithium Battery Chargers?
Lithium batteries are advantageous over lead-acid batteries in certain areas. They tend to charge faster and are lighter in weight. They also tend to have a longer cycle life. However, they need precise charging to function properly.
You’ll want a charger that is reliable and well-constructed enough to provide a complete charge. Otherwise, a low-quality lithium battery charger will lead to incomplete charges, a shorter battery life, and other issues. That’s why finding a good 24V lithium battery charger can ensure your battery stays functional for the long term, especially when it provides you with features such as overcharge protection and temperature compensation.
What to Look For in a 24V Lithium Battery Charger?
It may be a good idea to carefully look through the key features of a 24V lithium battery charger. We will list off some of these to ensure you can find one that will provide the best benefits while fulfilling your most critical needs. Here’s a look at the following:
- Compatibility: Make sure the charger is compatible with lithium batteries. This includes chargers with selectable chemistry modes so your battery gets proper charging.
- Amperage Rating: Higher amperage can allow a battery to ensure quick charging. However, the size of the battery does play a role in charging speed, especially in the case of 24V lithium batteries. These may be constructed from multiple cells configured for a 24V nominal voltage or by connecting two 12V batteries in series—a common practice in certain systems. This setup impacts how the charger interacts with the battery and influences overall charging efficiency.
- Safety Features: Look for features like reverse polarity protection and over-temperature protection that ensure the health of the battery is not harmed.
- Durability: Ideally, the durability means whether or not it can be used in outdoor environments or storage spaces where the temperature may be low enough to where it can cause discharge and degradation of the battery.
The Best 24V Lithium Battery Chargers: Our Top Options
Here’s a look at 24V lithium battery chargers that we believe are best suited for such batteries. It is important to make sure you pay close attention to some of the features to determine if it is the best fit for your critical needs. Let’s go over the following options:
Battery Tender 5 AMP 12V/24V Selectable Battery Charger and Maintainer
First, we’ve got the 5 AMP 12V/24V Selectable Battery Charger and Maintainer. This might be one of the best options for charging a lithium battery, including 24V or two 12V batteries in series. It has a selectable option allowing you to choose between 12V and 24V. It has a current output range of 3 to 5 amps, making it appropriate for a solid output charge.
It also has a “connect and forget” feature where you can set it up and let it charge. Once your battery is fully charged, it will reach a float mode, which will maintain the battery’s charge accordingly. This means you won’t have to worry about unnecessary discharge, nor will you have to deal with the dangers of overcharging. It’s suitable for the storage of vehicles that are powered by lithium batteries, especially if you’re not using it during the winter months. Plus, it’s got weather-resistant housing that can handle such rugged conditions.
When it comes to flexibility across voltage types on one charger, it’s this one in particular that fits the bill. Be sure to put it to good use for lithium batteries, whether they are 24V or 12V.
Key features:
- Amp output range of 3-5 AMPS
- Selectable between 24V and 12V batteries
- Compatible charger for Lithium, AGM, GEL, and Standard (Sealed or Flooded Lead Acid) batteries
Battery Tender PowerPlus 24V 20 AMP On-Board Battery Charger and Maintainer
If you have a lithium battery that powers something more demanding, then you’re going to need this battery charger and maintainer. Of course, it comes with plenty of professional-grade power that can work to your advantage. Plus, you can mount it to keep it on board for vehicles such as boats or RVs. It’s got an automatic maintenance mode that switches on once your battery has maintained its necessary charge.
The durability of this device is pretty rugged. It is corrosion resistant and can withstand numerous conditions, such as water, salt, and dirt. In a sense, it’s pretty tough when it comes to its housing. It’s got spark-proof features and reverse charging protection, denying you the charge if you inadvertently connect this device the wrong way.
If you are looking for a 24V lithium battery charger that will be a better fit for high-performance batteries (and the vehicles that they power), this charger is the best option. It’s great for those who prioritize power and long-term reliability.
Key features:
- LED status indicators for displaying charging status
- On-board mounting features (for applicable vehicles)
- Compatible charger for Lithium, AGM, GEL, and Standard (Sealed or Flooded Lead Acid) batteries
Maintenance Tips for Lithium Batteries
With the two top options listed above for 24V lithium battery chargers, let’s turn our attention to maintenance tips. Your lithium battery can have an extended lifespan and continue to perform at such an excellent level of reliability if you commit to performing proper maintenance whenever necessary. Here are some tips you can follow:
- Avoid Deep Discharges: If the battery is around 20 to 30 percent capacity, this will be a good range to start recharging it. Don’t let it hit 0 percent regularly, as it could lead to a shorter battery cycle life and reduced performance over time.
- Store at a Partial Charge: If you are not using a lithium battery for lengthy periods, consider storing it at around 50 percent.
- Use a Charger Compatible with Lithium Batteries: Make sure the charger you choose is compatible with lithium batteries. They can be specifically designed or have a selectable chemistry feature. Do not use a 12V lithium charger for 24V batteries. This procedure is not only ineffective but is also unsafe, as it can lead to battery imbalance or damage. You should always use a charger that matches the voltage of your battery.
- Monitor the Battery Health Accordingly: By knowing the health status of your battery, you can easily determine if it’s in good condition or if there is a critical issue where replacement is necessary.
- Avoid Extreme Temperatures: Charging and storing lithium batteries must be done in an environment where extreme temperatures cannot be reached, meaning they might not be allowed to charge in an outdoor space or a garage if the air temperature typically reaches extreme highs or lows in your locale.
Give Your Lithium Batteries the Charge They Need
When it comes to 24V lithium batteries, you’ll want to choose a charger that will ensure the best in reliability. The two options we’ve listed above are each designed for the appropriate type of lithium batteries to ensure long-lasting performance. You have one for standard needs and the other for those that are powering more demanding vehicles. Choose one that fits your situation best and use it regularly.
