How long should you leave a battery charger on a car?
Most car batteries can be charged in about an hour.
Is it worth buying a battery charger?
A battery charger is a very useful tool to have in a specific situation -- namely, when you'll be leaving your car unused for long periods of time. Every day that your car isn't turned on, the battery drains a little. That means that, if you leave your car in storage for a month or season, you may come back to find out that it doesn't start. An automatic battery charger attached to your battery during this period will fill in the power difference every day, ensuring that you come back to a fully charged battery. And, of course, it comes in handy to charge any depleted batteries you encounter in your automobiles or lawn equipment.
What are the two types of battery chargers?
The two main types of battery chargers are manual chargers and automatic chargers. A manual charger connects to a car battery and delivers power until it's disconnected or depleted. An automatic charger can read the power level of a car battery and will deliver enough power to keep it fully charged. While using a manual charger means you may run the risk of overcharging your battery, many automatic chargers aren't powerful enough to charge dead batteries.
What should I look for when buying a battery charger?
When looking for a battery charger, you'll want to consider several factors. First, you'll need to determine what kind of battery your car has -- most vehicles have lead-acid batteries, but many RVs have deep-cycle batteries. You'll have to decide whether you want a manual charger or an automatic charger, as well as how much power you need (more powerful chargers replenish batteries faster). Finally, you'll need to determine how much you want to spend on the battery charger.
Can you overcharge a car battery with a trickle charger?
No, you cannot overcharge a car battery with a trickle charger. Trickle chargers (also known as automatic or "smart" chargers) are able to gauge the level of charge your battery has and act appropriately, keeping it fully charged without overcharging it. Since draining your battery and overcharging it can both be hazardous to its long-term health, trickle chargers are handy for keeping your battery in good condition, especially during periods when your car isn't in use.
Now that you know what are the benefits of using a good battery charger for your car, it is important to find the right one for you. There are many different types of battery chargers available on the market, it is important to find one that can meet your specific needs.
