It is important to check the meter to see if the battery is charging properly. If the meter reads low, it is likely that your battery does not need a charge, or that your ground connection is not secure. When this happens, you need to switch off the charger, disconnect it, then plug it back. If the charger does not begin to charge even after a few minutes, then it means that your battery is dead beyond recovery.
To ensure that your trickle charger is working, you can also try using it n a different battery. If there is any movement in the ammeter needle from zero, then it means that the charger is functioning. Consequently, the issue lies on your battery. In this case, you can always learn how to know if your battery is dead. I am testing my 24v trickle charger — when connected to batteries reads You can use a trickle charger around 1 amp to charge any lead acid battery regardless if it has removable caps or is sealed.
Some articles state to connect the ground lead to some part of the vehicle ground system and not the battery. This is true IF the battery is still in the vehicle. This can help eliminate arcing and sparking.
I always wipe it clean too because there are usually trace voltage losses through dirt and grime over any lead acid battery. If the car that needs the trickle charge is in and enclosed 2 car garage with doors down, will that be an issue? Keep the charger connected until the battery charging is complete. You might think that all trickle chargers are created equal, but there are several different options you can actually choose between. The most basic trickle charger simply is a low-amperage option that slowly increases the charge level in the battery.
These do include the risk of overcharging a battery, however, it will take a long time to get to that stage. It is best to know the level of charge of your battery before you start charging though, and to monitor that throughout the process so that you know when to disconnect the charger.
Overcharging, even at a low rate, is always dangerous. Then you get options that have a few more bells and whistles. They tend to be more expensive, and prices can range depending on which extra features your trickle charger has. The most common feature is a built-in monitor that detects the level of charge in the battery for the entire time it is connected.
This often comes with an automatic shut-off that stops the charger from operating once the battery reaches its full capacity. These are your entry-level smart trickle chargers.
The next level is a fully smart trickle charger. This type will come with a monitor and the automatic shut-off function, plus the ability to continue monitoring the level of charge once it has shut off and turned itself back on once the battery level has dropped to a specified charge capacity.
The cycle will continue until you disconnect the charger from the battery. How Do They Work? James Olive September 13, James Olive April 1, Save Saved Removed 0.
When and how to use a trickle charger So why would you need a trickle charger? How long does it take to charge a car battery with a trickle charger?
How to connect a trickle charger to a car battery? Does it just need to be kept charged until its next use? Questions like these help to determine if you need a regular battery or a trickle charger.
Did you know? Charging a battery too fast can damage the battery, reducing its performance capacity, shortening its life cycle and even cause it to catch fire. This means that you have to check the battery and make sure to not let the charger stay connected past the point of a full charge.
That will help you avoid mistakes many batteries owners make. Is it right for you? Lead-acid batteries store electrical energy via a series of lead plates and an electrolyte solution of sulfuric acid, so when a battery discharges , the lead plates undergo a chemical transition into lead sulfate, while the electrolyte turns into a dilute solution of water and sulfuric acid.
When you apply an electrical current to the battery, which is what happens when you connect a battery charger , the chemical process reverses. The lead sulfate turns, mostly, back into the lead, which releases the sulfate into the electrolyte so that it becomes a stronger solution of sulfuric acid and water.
Although applying a higher charging amperage speeds up this reaction and causes the battery to charge faster, doing so has its costs. Applying excess charge amperage can generate heat, and may cause off-gassing. In extreme cases, it's possible for a battery to explode.
To prevent this, smart trickle chargers can detect the charge level and automatically adjust the amperage. When the battery is very dead, the charger provides more amperage, and it slows as the battery nears full charge so that the electrolyte doesn't off-gas. In most cases, a trickle charger is more of a luxury than a necessity. However, they aren't expensive, and it's a nice tool to have around. If you can afford to leave your car with your mechanic for a day and have them fully charge your battery—and check out both it and the charging system while they're at it—then that's great.
If you can't afford to be without your car, picking up an inexpensive trickle charger would be a smart move. Make sure you follow safe charging practices and avoid overcharging the battery, especially if you go with a cheap manual trickle charger. Both chargers can help keep your car battery from dying , but the main difference is electrical current output. A trickle charger slowly outputs current at a low amperage continuously, whereas float chargers supply electrical current only when needed.
For this reason, float chargers can stay hooked up to a car battery in storage without the risk of overcharging. Battery maintainers or battery tenders supply small amounts of current over extended periods to keep a vehicle's battery charged when it falls below a specific voltage.
Unlike trickle chargers, battery maintainers automatically enter a standby or float mode to prevent overcharging while connected to a vehicle. Set the switch on the front of the trickle charger to the correct voltage for the battery and then connect the clips to the battery terminals. Next, plug the charger into an outlet and turn it on.
