The Best Auto Battery Chargers
Different Types Of Batteries
According to Wikipedia, "A battery charger is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it." Whether a battery takes a charge depends upon the size and the type of battery being charged. There are 3 main types:

Different Types of Chargers
Many people use an automatic charger. When you try to charge up a battery and you are using a digital charger, will it work? A digital instrument will tell you if the battery falls below the 80%. Many people say it can't be recharged if it falls that low but it is not necessarily true. Some batteries can be rejuvenated and just need a charge to start, depending upon the age of the battery.
One customer had a problem with a generator. His battery charger indicated it was dead. He was using an automatic charger but you can have problems with an automatic charger too, if you battery falls below 80%. A battery has to have a certain amount of charge for it to start charging.
You need to understand how to check batteries. Auto parts stores will tell you that your battery doesn't have enough voltage so they can't charge it. What I recommend is to keep putting low voltage back in to your battery and see if it will come back up. A trickle charger may not bring it up at all because a trickle charger needs a certain amount of voltage for it to recharge. Sometimes you have to have a manual charger in place of an automatic because an automatic has to have voltage to start it.
Problems With Battery Chargers
Charger might tell you that your battery is dead when it still could be a good battery and be fully charged. Chargers can be deceiving. Problems can occur when trying to charge you battery.
Chargers go bad.
Battery dropped below their 80% level.
If it's a newer battery, it may come back up if it didn't kill a cell. A hydrometer is a tool that will test for a dead cell by checking the electrolytes. With sealed batteries, you can't open them to tell. If your automatic charger says it's dead, then try and put a little charge back in to it, manually and slowly. But be careful! You don't know the condition of the battery. It's dangerous. You could blow a battery apart.
Batteries can get complicated. Automatic chargers may not recharge your battery. You may need to use a manual charger to bring up your battery. Another opting is to bring it to an auto parts dealer and have them charge it for you. They use sophisticated equipment.
Some people are wasting money and filling up the garbage dumps with batteries because they are incorrectly charging them. Don't waste money. Make sure your batteries are completely dead before replacing them.
