FAQs

Is this a smart charger?****

Yes, it is.

What is the input voltage?****

It is 5V DC.

What is the output voltage?****

It is 4.2V DC.

How many batteries can be charged at one time?****

It can charge two batteries at one time.

Can a battery charger be left on all the time?****

Yes. We encourage users to leave the charger connected to the batteries and AC when storing the application. Once the charger completes its charge, it will begin monitoring the voltage of the batteries. Lead-acid batteries self- discharge over time and the self-discharge rate increases as batteries age

How long does a battery charger need?****

Depending on your battery charger, it may take 4-8 hours to charge your battery enough to start the car a few times. It may take 10-24 hours to charge your battery up to 100 percent. The longer you charge it, the more strength the charger can put in the car batter

How do you know when a battery charger is fully charged?****

The battery is fully charged when the current drops to 0 or no longer decreases or the automatic charger switches off.

How long should you leave a battery charger on a dead battery?****

Actual battery chargers take 10-24 hours to charge a car battery. That’s the fast, smart chargers. If you’re using a trickle charger, you could be charging your battery for three or more days. Charging slowly protects the battery.

What is the voltage of a battery charger?****

For the simple and often cheaper battery chargers, the charge current is specified for the nominal battery voltage (= 12 or 24 V). Charging a battery requires a higher charge voltage, namely 14.4 or 28.8 V.

Are all battery chargers the same?****

No, not all battery chargers are the same. Battery chargers can vary significantly in terms of their charging speed, the type of battery they are designed to charge, their voltage and amperage output, and their features and capabilities.

How do you calculate battery charger capacity?****

Most battery manufacturers recommend sizing the charger at about 25% of the battery capacity (ah = amp hour capacity). Thus, a 100 ah battery would take about a 25 amp charger (or less). Larger chargers may be used to decrease charge time but may decrease battery life.

How many amps does a battery charger use?****

A basic charger usually charges at around 2 amps – and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery. But there is a wide range of chargers with different charge rates on the market – from 2 to 10 amps. The higher the charge output, the faster a flat battery is recharged.

How many types of battery charging are there?****

There are three common methods of charging a battery; constant voltage, constant current and a combination of constant voltage/constant current with or without a smart charging circuit.

Where do you ground a battery charger?****

You need to ground the charger before hooking it up to the battery. A grounding clip is typically included with the power source. Attach it to a clean section of the vehicle’s frame. You’ll need to investigate the undercarriage in this case.
