Can You Leave A Car Battery Charger On Too Long

Old battery chargers have the tendency to overcharge the battery if left too long – after recharging wet/flooded lead-acid batteries, it is recommended to always check the level of the electrolytes and to add distilled water if required.

AGM and Gel-Cell lead-acid batteries should be recharged with advanced multi-stage lead-acid battery chargers that monitor battery condition and switch automatically between modes, preventing overcharging the battery and often maintaining the battery for a longer period of time.

What Is An Amplifier

An Amplifier is a circuit that can gain power more than one. Now it can be a separate piece of equipment or a tool or it can be an electrical circuit carried or contained within another equipment or a device. Amplification is a rudimentary/foundational or a base to modern electronics and is broadly used in almost all electronic equipment.

In this blog post, were going to take a look at how long it takes to charge an electric car at a charging station. Well also discuss some of the pros and cons of using an electric car. So, if youre considering making the switch to electric, read on!

How I Estimated The Charging Times For Each Charger And Battery

When I did the calculations above, I borrowed the initial set-up of the chart from Schumacher which is a battery charger manufacturer. I essentially extrapolated their chart that they use for their 1.5 amp charger to get a baseline for all of the other values.

The charts have ranges depending on the CCA or RC of your car battery. Your car batterys rating will be on the sticker on the top of the battery.

After you locate where your car batterys rating fits, you will see an estimate for the charging time depending on whether or not it is completely dead or half dead .

In the chart seen here , youll notice that the first two categories are in Amp Hours but that car batteries are rated in Cold Cranking Amps or Reserve Capacity .

In order to estimate how long a charger will take to charge, we need to get the car batteries to an Ah equivalent rating because, for example, a 4-amp charger, will generally replenish 4Ah within a battery per hour .

In order to see how Schumacher treats the different classes of car batteries with regards to AH, I did a little math.

Lets take the 32Ah battery from the image above. It says that a time of 13.5 hours is needed to bring a 32Ah battery back to full charge from 50%.

32Ah / 2 = 16Ah that needs to be replaced. 16Ah / 13.5 hours = 1.19 amps per average hour from the 1.5 amp charger.

The 6Ah battery in the image needs 3Ah recharged, so 3Ah/2.5 hours = 1.2 amps per average hour from the 1.5 amp charger.

Will A Trickle Charger Overcharge My Car Battery

Yes, a trickle charger that is not a smart charger operating in float mode will eventually ruin your battery if left connected over time. Trickle chargers continue to pump a small current into the battery even if the battery cant accept it. This slowly evaporates the electrolyte through electrolysis .

If you have an older trickle charger, be sure to remove the cables shortly after the battery has reached its full charge.

If you have a modern smart charger that has a float or maintain mode, you can leave these hooked up indefinitely, as they only give out current when the battery naturally self-discharges.

Charging At 50 Amps Is Fast But Stay Safe

A 50 amp charger sounds great. But you should be wary. At that rate, there’s a risk of overheating the battery.

Higher amps means a faster charge. Problems are more likely to arise if you leave the charger connected long after the battery is fully charged. No matter which charger you use, you should always promptly remove it once the battery has a full charge again.

You can avoid this danger by sticking with a slower charger. A 10 or 12 amp charger gets the job done safely in a reasonable amount of time.

Calculating How Long The Battery Could Charge:

We have already mentioned the factors for charging the battery that is, how much power has been left and the rate of amp that we are charging it at. Now, for example, take a two amp charger. Determine how many amps are missing from the battery and find out about the time to charge through simple Mathematics by taking the amount that is missing and after that divide it by two. Suppose, we have a 50 amp battery that is half depleted, so it has 25 amps missing. One can divide 25 by two and will get 12.5. As a result, the battery will take 12.5 hours to get fully charged

Will A Trickle Charger Charge A Dead Battery

Yes, trickle chargers can charge dead batteries. But compared to 40-amp chargers, it takes time to recharge dead batteries with the 1-amp and 2-amp trickle chargers. It takes 24 hours to charge a dead battery with a 1-amp trickle charger. Meanwhile, you can bring back to life a cars dead battery in 12 hours with a 2-amp trickle charger.

Smart chargers cost more than trickle chargers and 40-amp chargers. If you need a more cost-effective car battery charger, it may be wise to invest in trickle chargers. You can spend less with a 1-amp trickle charger despite the 24-hour wait you may have to contend with when charging your cars battery with it. But at least you dont have to run the risk of overloading your cars battery like when using the 40-amp chargers.

There is, of course, always the choice to invest in the 2-amp trickle charger to cut your charging time to half that of 1-amps 24 hours charging time.
