How to charge a battery-6 Ways for the best results

So charging your batteries, is a thing that I do keep harping on about. However I do believe that it is the single cause of batteries that fail after winter storage. It’s important to charge batteries correctly if you want them to work well and last a long time. So, different types of batteries and uses need different ways to charge them. Here are the most popular ways to charge a battery:

Constant Voltage Charging:

This is probably one of the first type of battery chargers that I came across as an apprentice mechanic. The charger was a great big thing with a few pointy needles. Looking like something from “Star Wars” movies.

Ironically though, Lead-acid batteries work best with this method of charging. The battery is charged until it reaches its maximum charge level at a constant voltage. The voltage is then brought down to a maintenance level to stop the battery from getting overheated and too charged.

Float charging:

If I remember correctly this type of charger became very popular. Float charging is the best way to keep a battery in good shape for a long time. We could keep the charge level, at a constant low-level voltage, which was sent to the battery. This is the best way to charge backup batteries that don’t get used very often.

Trickle charging

This is the type of charger that I recommend for charging motorcycle batteries up over the winter period. Subsequently, it is a slow, low-level way to charge so that the level of charge stays the same.

This method is good for motorcycle batteries that are only normally used in the summer months. The Smart charger keeps them from getting sulphated and losing their power.

Pulse charging:

This enables short pulses of high current which are used to remove sulfation from the battery plates. This makes the battery work better and last longer. This method is perfect for lead-acid batteries that have been stored for a long time or have a lot of sulfation on them.

Pulse charging may be able to charge at even higher rates without gassing if it can get a burst of current into the cell before it starts to gas.

Smart charging

This is now bringing us more up to date with charging systems.  So this is an intelligent way to charge that uses advanced algorithms. Of course, to give your battery the best charging profile.

 This method can figure out the type of battery, how much voltage it has, and how hot it is, and then change the charging current and voltage to match.

Until technology surpasses this charger then it is the “bee’s knees” of battery chargers.


How to charge a battery by using the most appropriate battery charging method for you. So will no doubt give you the best performance and longest life from a battery? Hence it all depends on using the right way to charge it.

All the methods that I used on the old charging machines finally gave me a charged battery. However now a days the machines have also to be good looking and modern. Generally though whether you’re using a lead-acid battery or another kind. So there are different ways to charge it that can help keep it charged and stop problems like sulfation (the main enemy of lead acid batteries) and capacity loss.

Charge a battery, by choosing the right charging method for the type of battery and how it will be used, you can make sure the batteries are always charged and ready to go.
