Is it OK to charge battery with 10 amps?
For car batteries, it is always recommended not to fast charge them by using a charger that exceeds 20 amps because it can damage the battery, and it may affect its performance as well. Therefore, slow charging by using a 10 amps charger or less is mostly considered to be better.
Will a 10 amp battery charger charge a car battery?
Answer provided by Typically, a 10 amp battery charger will take approximately four to 11 hours to fully charge your car’s battery.
How many amps does a 10 amp battery charger use?
As you can see, even though the charger is rated at a maximum 10 amp charge rate, it would only be able to deliver 3.6 amps at 12.6 volts and that is not taking into account any efficiency losses that are usually in the 10 to 20 percent range reducing the charge current even more.
What’s the difference between a 5 amp and a 10 amp battery charger?
The higher the number, the faster they will recharge. A 5 amp charger will re-charge mid-range batteries fully in 10-12 hours and should be fine for most fishermen. But if you need lightning fast recharges, or if you have batteries that are 120 amp hours or higher, we recommend purchasing a 10 or 15 amp charger.
How long should you charge a 12-volt battery at 10 amps?
A 10 Amp charge will take 4-7 hours to fully charge the battery, a 2 Amp charge will take 1-2 days. You don’t need to charge the battery to start the car.
How many watts is a 10 amp battery charger?
A charger may be marketed as being capable of charging at 10 amps, but in reality, it may only deliver 50 watts of energy. A 50-watt charger could indeed charge a battery at 10 amps, but only if it’s a 1S LiPo pack. Using our formula above, the practical amperage delivered by the charger is actually 50W/4.2V=11.90A.
Do I need a 5 amp or 10 amp charger?
Yes, the 10 amp will charge faster than the 5 amp. If your like me and have a foot on the trolling motor 90% of the day AND you need to get back on the water the next day, a 10 amp or more is needed. Tourney guys run either 10 amp or 15 amp chargers.
How many amps is a 12V charger?
A medium amp output 12 volt charger would be in the range of 20 to 50 amps or so, and be used for many applications using about 100 amp hours of battery and up, or applications with a constant amp load (power supply application).
How do I know what size battery charger I need?
Compute Charger Size Using Battery Ampere-Hours
- ((AH x K)/T) + L = I where.
- AH is the ampere-hour capacity of the battery. K is the battery recharge inefficiency constant (1.15 for lead-acid and 1.4 for Ni-Cd)
- ((45 x 1.4)/24) + 0.8 = 3.425 amps.

What’s the difference between a battery charger and a trickle charger?
A trickle charger never was the “best way” but thankfully new generation of “battery chargers” is on the market, which do the job nicely. The difference between a trickle charger and a battery charger is that a trickle charger constantly applies a charge, whether the battery is fully charged or not.
What amp should I charge my 12V battery?
Most battery manufacturers recommend sizing the charger at about 25% of the battery capacity (ah = amp hour capacity). Thus, a 100 ah 12 volt battery would take about a 25 amp 12 volt charger (or less). Larger chargers may be used to decrease charge time, but may decrease battery life.
How many amps should my battery charger be?
As a rule of thumb your battery charger should be a minimum of 10% of the Ah rating of the battery. E.g A 100Ah battery would require a 10 Amp charger as a minimum. To prevent overcharging you should keep the charger size to within 20% of the total capacity.
