Battery Charger and Portable Generators

There are many generators on the market that have an electric start. Most of these generators use a 12 Volt battery to start the engine. As well as nearly all standby generators use a 12 Volt battery to start their engines automatically.

These batteries need to be kept fully charged in order for them to have sufficient power to start the engine of the generator. Well thought out generators are designed to charge their batteries when they are running.

Sometimes if the generators are not run in a long time the batteries will tend to lose their charge and thus cranking power. It is at these times that you need to recharge the battery with an external battery charger.

120V Battery Chargers

Battery chargers are available that run on 120 volts and can recharge the stored batteries. There are different types of battery chargers available, some of these chargers have multi functions and can either charge a battery quickly in minutes for a quick charge as well as being able to charge them at a slower rate which would charge the battery in a few hours and also have a function of trickle charge which helps to maintain the charge in the battery.

6 and 12 Volt Flexibility

Some battery chargers like the Schumacher SEM-1562A-CA 1.5 Amp Speed Charge Battery Maintainer are flexible enough to charge both 6 Volt as well as 12 Volt batteries.

You can also find battery charges that are designed to just maintain your battery. These are known as trickle chargers, although you can also charge your battery with these chargers, though they can only charge your battery at a very slow rate.

Generator 12V Charging Capability

Some of the generators are equipped with a 12Volt DC outlet. These generators can also be used for charging batteries. You can find this option on many portable generators though not all of these generators are equipped with an electric start and do not have batteries installed. The 12 Volt DC outlet when connected to the terminals of a 12 Volt battery provides the ability to charge these batteries when the generator is running.

Price Ranges

Battery chargers are usually portable and they vary in price from $20.00 like the Battery Tender 021-0123 Junior 12V Battery Charger to over $140.00 like the Schumacher SE-4022 2/10/40/200 Amp Manual Wheeled Battery Charger and Tester.

You can find battery chargers that can automatically charge your battery as well as chargers that have to be manually set to charge the battery.

The price of these battery chargers depends on the functions that they can perform as well as whether they are heavy duty meant to be used in a workshop or light duty and meant to be used at home. The heavy duty battery charges have a heavy duty construction and some of these can charge more than one battery at a time.

Battery Charger Summary

A battery charger is a very useful piece of equipment to have at home. If you own a car or a riding mower or any other equipment that uses a battery to start the engine, having a battery charger means that you are always sure that you will be able to start your equipment.

Depending on use that you would have for a battery charger, you can always find one that suits your budget while meeting your need. Having one available when you need it can save you a lot of frustration if the battery on your equipment runs down.
