A 12v car battery charger is a charger that appears in a solid-state, and it's fully designed to ensure that your car 12v car battery is fully charged and the charge is maintained. The unique quality of the 12v car battery chargers is that they can be plugged in for as long as possible; it may be hours or days within a week.
The best thing about this charger is that it is created in a way that your battery may not be exposed to reverse polarity, over-voltage, short circuit, and over-current, among others. 12v car battery chargers are known to be light making them easier to use in multiple cars. During charging, these types of chargers are efficient as they automatically detect when the battery is fully charged where they ensure that the voltage of the car and battery is maintained.
What is the best 12 v car battery charger?
There are various best 12 v car battery chargers, and some include; the black tender 021-0123, Schumacher DSR 131, black decker BM3B, black tender 021-0128, NoCo Genius G750, and Schumacher SC1280, among other charges.
The overall best charger is the black tender 021-0123, which is an automatic and lightweight charger. Qualities such as its lightweight ensure that a car battery is always charged and maintains charge. In short, it has four steps in its entire charging process, and these include; initialization, bulk, absorption mode, and float or rather the maintenance mode. With this charger, the user should be confident enough since it can never allow an overcharge to the batter; hence the risk of damage is minimal. In addition, this type of charger protects against reverse polarity or simply its spark proof.
The Schumacher can be used for charging both a 12v and 6 volts battery. It is has a cooling fan that enables it to have a longer lifespan as well as it has a microprocessor that helps in regulating the amperage rate of charge automatically. It is effective because it can charge multiple types of batteries, such as those of AGM, Gel, and deep-cycle batteries. In addition, this charger may be used in cars with big engines and others like trucks and SUVs.
Can you charge a 12v car battery with a normal charger?
Basically, any charger can charge a 12v car battery; however, the rate at which the battery is charged differs. For example, one may decide to use a fast charger that will only take around 6 hours to fully charge your battery; at the moment, that will be satisfying, but at long last, the battery gets bad.
Different from a normal charger, a 12v car battery can be charged using a solar panel. This type of charger charges a battery depending on the size of the battery, and in most cases, it may take around 5-8 hours to fully charge a 12v battery.
With normal chargers, the process of charging is easy. One is required to connect the battery to the charger by attaching the negative black cables of your charger to the batteries, negative terminal. In addition, do the same with your positive terminal and the positive red cable. One may use a normal charger for the 12v car battery, but only if the charger can get to power the correct voltage of the battery.
How long does it take to charge a 12v car battery?
A 12v car battery can get charged for around 12 to 24 hours to full charge. For any battery, it is advisable for slow charging to ensure that the batteries don't go bad. For a 12v battery, it takes time to fully charge, and charging it slowly allows it to maximize its charge. It is important to note that in case your battery gets too hot when recharging then, you should immediately stop charging it.
To simply know how long your 12v car battery will take to charge then, you need to be aware of your battery's reserve capacity as well as your chargers output charge current. For example, if you're charging a 100aH battery with a charger with 10 A, then it will be fully charged within 10 hours. It is advisable, however, to use a low amp charger than a high amp charger because the chargers determine the condition of your battery over time. The low amp charger is efficient mostly because it maintains your 12v car battery at a full level charge.
Normally the higher the amperes of the charger, the higher, the faster your battery will get charged, while the lower the amperes, the more time it will take your battery to fully charge. For example, if you charge your 12v car battery at four amps, then you expect your battery to fully charge after 12 hours. All car batteries normally have their batteries at 48 amps, and this means that using a 4 amp charger, your battery will charge at four amps per hour, then taking 12 hours to completely get the required 48 amps.
Using a 2amps charger compared to that of the four amps charger, it shows that more time will be required to fully charge your battery, which in this case will be 24 hours. It is evident that the best charger here is the one with 2amps since it takes longer to charge, thus ensuring minimal damage to your car battery.
It is evident that a 12v car battery nay is charged with a normal charger but only if it has met certain conditions. A good 12v car battery charger takes around 12 to 24 hours to fully charge a battery; if lesser time is used, then one should remember that their batteries are at the risk of getting damaged. More is that with the 12v car battery and any other battery for that matter, the higher amps a charger has, then the lesser time it will take to complete a full charge. Experts, however, advise that the best charger is that which has low amps. The best 12v car battery charger as of 2020 is the black tender 021-0123.
