Battery care for vehicles sometimes takes a back seat in terms of priority. You only get to focus on it when things go wrong. By then, it’s usually too late. Whether it’s for regular driving, trailer or camper driving, the battery is one of the most critical components of your vehicles. The best way to take care of your batteries is to ensure the proper level of charging with the appropriate charging speeds and current. Using DC to DC chargers is one of the recommended ways to achieve this.
What DC to DC Chargers Are
Especially important for multi-battery setups, DC to DC chargers ensure that your batteries are carefully balanced and isolated from each other. This gives you a predictable and reliable performance when you need it. A DC to DC charger always keeps your second battery at 100% charge, even if it’s located far away from your alternator.
Moreover, since it’s a DC power supply, the DC to DC charger isn’t dependent on the fluctuations in current coming from the alternator, giving you a more steady supply and lessening the abuse on your car’s electrical system. DC to DC chargers are very helpful for camper setups wherein you have your auxiliary batteries far away from the engine.
How to Select the Best DC to DC Charger
Here are pointers to help you choose the best DC to DC charger for your vehicle.
-
Top DC to DC chargers can determine the type of batteries you have.
Many battery types are now available in the market. These include the conventional lead-acid and calcium batteries, as well as the more expensive and sophisticated AGM (absorbent glass mat) and lithium batteries in the auxiliary power roles.
The best DC to DC battery chargers in the market can detect the type of batteries in your car’s electrical system, and give the proper output that’s required. Battery types have different charging requirements and may get damaged if they’re given improper charging currents.
-
The best charger can accept multiple inputs.
Another factor that you need to consider is if the DC to DC charger can accept different power inputs. The engine’s alternator is a vehicle’s main power supply. As such, the alternator regulates the proper supply input to give the adequate required voltage and current for the battery.
Some 4×4 and camper van enthusiasts now also bring their own auxiliary power sources, such as solar panels. Having your own solar panels with you gets increasingly useful, especially when you’re driving and setting up camp in the desert. You may set up your camp and charge your batteries while you’re resting. The perfect DC to DC charger brand should be able to accept this auxiliary power supply.
-
The ideal DC to DC charger caters to your battery size.
Similar to getting a charger that’s compatible with your battery type, another variable is getting one that can cater to your car’s specific battery size. Battery size doesn’t refer to its actual physical size. Rather, battery size pertains to how many amp-hours your battery can store.
A full-size auto battery has different capacities compared to a deep cycle marine battery. As such, it would have different charging time requirements. You need to have a DC to DC charger that’s perfectly suited to your vehicle’s battery size in order to ensure the battery’s long life and reliability.
-
The best charger will meet your purpose for purchasing a battery charging system.
Some users own offline chargers that make sure their spare batteries are being charged at home during the off-season. Offline chargers may be used for motorcycles, boats, or classic cars. In such cases, a low-current DC charger would be perfect. However, for heavier charging requirements and in-vehicle chargers, bigger and more sophisticated DC chargers may be necessary.
-
It can withstand high temperatures.
Check the DC charger’s working temperature limits when you’re shopping around. For the camping and 4×4 enthusiasts who use in-vehicle chargers, another major item to carefully consider is the temperature limits of the unit. Some drivers use their vehicles in the most extreme weather conditions and abuse all of the car’s components heavily. The hot conditions in the engine bay and wherever you might install the charging unit may damage low-quality DC chargers. This will give you more problems when you’re driving in the outback.
-
The ideal charger has the proper indicators and selectors for different charging requirements.
A battery charging system should have the proper indicators and display, which will give you an idea of its current status. Some important information that you need to be able to see on the charger are the following:
- Type of battery being charged
- Current charging level
- Fault status
You should be especially aware of the fault status at any point in time, giving you ample time to react when needed.
Conclusion
As a final note, purchase a DC to DC charger that can offer you the best warranty for your purchase. As part of its long-term reliability, you need a charger with a good warranty to give you peace of mind. High-quality manufacturers give longer warranties, showing their high confidence in their products.
