## Can a converter be used as a battery charger?

The two terms are used interchangeably because for the most part, in modern RVs, an RV converter charges your batteries and converts shore power to usable 12v DC power. Simply, an RV converter is also a battery charger but with added capabilities.

## Is a converter the same as a battery charger?

In RV applications, the terms ‘power converter’ and ‘battery charger’ are used interchangeably. The converter takes AC power (from shore power or a generator), converts it to DC, and uses it to charge the RV batteries.

**What is a converter battery charger?**

Let’s begin with a simple description: A Converter Charger is a device that Converts 110 Volt AC (household) power into 12 Volt DC (battery) power and simultaneously charges the RV batteries.

### Do I need a fuse between battery and converter?

Yes a fuse is needed near the battery.

### What size converter charger do I need?

If only a power rating is given (watts), divide it by 12 volts to convert it to amps. Add up the amps of the appliances you’re likely to use at the same time. This is the minimum size power converter needed.

**Do I need a converter if I have an inverter charger?**

If it’s an inverter-charger, you don’t need a converter. If it’s just an inverter, you still need a converter to charge your batteries.

#### Is it better to charge a battery at 2 amps or 10 amps?

You would use 10 amperes on a car battery and 2 ampere on whatever small batteries you might want to charge that still use the same voltage. For example, a motorcycle battery could use the 2 ampere charging option.

#### How long does it take to charge a 12-volt battery with a 10 amp charger?

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.

**What size fuse do I need between battery and inverter?**

For example, if you have 1500 watt power inverter, you should be using a 175 amp fuse on the cable between the battery and power inverter….Fuse Size Between Battery and Power Inverter.

Inverter Capability | Fuse Size | Location (Positive) |
---|---|---|

500 watt | 50 amp | Close to battery |

1000 watt | 100 amp | Close to battery |

## What size fuse do I need for my inverter?

Recommended Inverter Cable, Breaker & Fuse Sizing

Inverter Voltage | Continuous Watts | Fuse Size (DC Amps) |
---|---|---|

12V | 800 | 110 |

1000 | 200 | |

1500 | 300 | |

2400 | 400 |
