How to Choose The Best Marine Battery Charger
We’ve been through the reviews, now let’s discuss the features.
One of the main elements to consider other than the brand is the number of banks available in the charger. The more banks, the more batteries you can charge simultaneously. Therefore, your batteries will be charged to their maximum capacity in less time.
Keep reading for an extensive guide on what to look out for in your new marine battery charger.
There’s a massive range of batteries available with varying charging requirements, so you must understand which battery type you have.
Some of the most popular batteries available are flooded lead-acid batteries, AGM, gel, and lithium-ion. Don’t worry; each different battery charger will state which batteries it does and doesn’t support.
The marine battery charges in my selection support several battery types; however, you should never assume that your battery will be covered! ALWAYS check before making your purchase.
The most effective battery chargers have microprocessors that can ready your battery type and modify its amperage and voltage to meet the demands.
Double-check that your marine battery charger can provide the right amount of voltage for your battery. All batteries vary in their voltage requirements.
Often, marine batteries run using a 12V system, however, this will won’t apply if you want to charge other items, for example, your SUV battery.
You should consider whether your charger needs to be capable of various charging powers. Some chargers have the ability to switch between charging 6v and 12v manually or even better, automatically.
The durability requirements of your battery charger depends on your environment. If you’re on a boat, your charger will need to be able to withstand shocks and have waterproof protection.
Also, try looking out for a charger that’s anti-corrosive and saltwater resistant.
If you’re using your trickle charging during off-season in a more sedate environment you won’t need to be concerned about waterproof and shock protection, although those features are a nice bonus!
Just like the rest of your electrical equipment, it’s important that your charger has built-in safety features to protect you from any nightmare scenarios.
The basic safety precaution that your marine battery charger should possess is protection against reverse polarity. Some chargers will automatically detect and diagnose when reverse polarity occurs.
Other key features include checking that you have enough fuses and protection against an excess of current, voltage and temperature. You need these features considering you will be leaving your charger alone for long periods of time.
If you have multiple batteries, you will benefit from a charger with multiple banks.
There are various options available;
2 bank marine battery charger
3 bank marine battery charger
4 bank marine battery charger
Something that you should consider is whether you’ll be purchasing more batteries in the near future. If you’re happy with one or two batteries, stick with a 2 bank marine battery charger. If you think you’ll be extending your collection, consider a 4 bank marine battery charger.
Recovery time refers to your charger’s ability to recover a battery once it’s fully drained.
Usually, the higher the amperage on your charge, the quicker it will be able to recover your battery. The necessity of rapid recovery time depends on how often you use your battery.
The best, and priciest, chargers will fully recover your battery in a few hours. If you’re happy to compromise on recovery time, a budget-friendly pick will work fine!
You need to select a size that’s compatible with your boat and you need to make sure that if you require a large charger, you have space to store it.
Generally, the larger the charger the more and power it generates. Also, the bigger the size the more banks it can carry.
If space is an issue, opt for a portable charger for easy movement and storage.
One common mistake is buying a charger that overcharges or undercharged your battery.
Overcharging the battery will cause it to overheat, risking permanent damage. To get the charger, identify your battery’s capacity. You can do this by locating the Ah rating that will be identified on your battery.
