Thing To Consider Before Buy

A number of considerations should guide your choice of a car battery charger. Factoring in these parameters would ensure you get the best suitable car battery charger for your situation. How about we learn about them?

Size

Over time, we have been lavished with game-changing technologies that have significantly shrunk the size of the car battery charger – making them much more compact. This was without limiting the capacity. There are now potent chargers that can fit comfortably into your palm.

While you should aim for portability when choosing battery sizes, don’t neglect their functionality. Some very portable chargers struggle to jump-start your battery if it is thoroughly dead. Some are quite bulky but have very powerful jump-start capacity.

Here is the catch: aim for a balance of portability and functionality when choosing the size of your car battery charger.

Charging Power

The charging power (which mirrors the ampere capacity) is a crucial consideration when buying car battery chargers. The charging power determines how fast it would charge your battery. Several charger brands have differing ampere range.

The ideal charger power for you depends on what you intend using the charger for. We agree that chargers with high charger power (lesser time to charge) tend to be costlier than those that take more time.

Chargers with high ampere have enhanced facilities which prevent your battery from completely dying. Of course, dead batteries are a menace when on the road.

With a charger with a higher ampere rating, you can readily jump start your battery and get you moving again without having to spend sizable time waiting for the charge up.

If the charger (with higher ampere) lacks the jump start capacity, its fast-charging power will ensure the dead battery charges up in no time.

Battery chargers with lower charging powers are still fantastic if you don’t frequently use the car but want to prevent scenarios where your battery completely dies from extensive disuse.

This is thanks to their trickle charging capacity. This reduces the weight of maintenance on your neck.

Ideally, you can get a charger with an ampere capacity of anywhere from 20 amps to 750 milliamps.

Voltage

The compatibility of your car with the prospective charger depends on a lot on the voltage of the charger. Take note that car battery chargers are versatile and not necessarily dedicated to just charging car batteries. Some chargers go as far as charging marine crafts and trucks.

While 12V is the general benchmark for car batteries, chargers in the market come in a voltage range. Some would charge batteries well above 40V while others could charge as low as 6V.

This gives chargers the flexibility to work on your small car and as huge as an industrial vehicle.

Automatic vs. Manual

Every car owner will admit that it is quite unnerving to check on the charge capacity perpetually. Thus, many are now resorting to automatic car battery chargers. This relieves you of the role of always having to check the charger to prevent situations like overcharging.

Most automatic chargers are designed to automatically switch modes once your battery gets fully charged. This means you wouldn’t have to worry about still piling charges on a full battery.

Agreeably, such a feature would increase the lifespan of your battery. However, we will admit that automatic chargers are significantly more expensive than manual ones.

It now depends on your budget and if you can shoulder the burden of a manual charger.

Maintain Charging or Fast Charging

The purpose or intended use of the charger will determine if you would go for fast charging or maintenance charge. If you will most times use the charger to maintain charge, then you most likely will not be keen about charging power (or charging speed). In that case, it is fine to go with chargers of lower ampere capacity.

However, if you will be using the charger for fast charging, then you have to prioritize the charging power. Should you be frequently using your car battery charge, it makes more sense to go for one with sufficient ampere capacity to charge your battery fast.

It would even be more beneficial (in such circumstances of regular use) to go for one with jump-start capacity.

Wall Socket Connector

You have to be mindful of the wall socket connector when buying a car battery charger. You have to get it right, especially for the country you are staying. Thus, you should factor in that socket wall connectors differ across different countries.

Make sure to confirm the wall socket connector used in where the manufacturer is located aligns with that used in your residence country. Otherwise, the manufacturer should make special provision for your country.

Charging Monitoring

It is not advised to buy a car battery charger that lacks an active monitoring facility. Charging monitoring gives you valuable information about your battery as it charges.

Most chargers with lower ampere capacity come with the active monitoring feature.

This tells you when your battery begins to lose charge, being not in use. This enables it to trigger the battery, activating it for charging. When the battery fully charges, it switches the battery off so that it doesn’t overcharge.

More advanced charger models go as far as telling how healthy your car battery is. They would inform you beforehand if your battery is dying permanently as well the charge capacity left in it.

Safety

Safety is one of the most important considerations when buying your car battery charger. You want a charger that keeps you and your battery protected. There are several safety functions to watch out for.

Reverse- polarity connection safety is one of the most important safety features your charger should have. This protects the electric system of your car in the event of a mistaken connection of the negative terminal to the positive or the positive to the negative.

It would be great if the charger is equipped with spark-proof functionality. This prevents unfortunate battery explosions when plugging your charger to a car battery leaking battery acid.

Your charger should have overheating protection. This prevents the charger from an explosion or fire outburst in events of rapid charging.

Another helpful safety feature is over-discharging protection. This prevents the wiring from frying in event of rapid charging.

It would be fantastic if your charger also has other safety features like float mode, battery tester, and clamp amps.
