Best DEWALT Battery Replacement?

DeWalt brand batteries are very popular among home users because they have high capacity and low price. They are made from durable materials like zinc alloy, stainless steel, or aluminum alloy. DeWalt brand batteries come in different sizes and capacities: 1Ah (standard), 2Ah (large), 3Ah (extra large) and 4Ah (ultra large). All of them offer good performance at affordable prices. However, there are some drawbacks with these batteries. One of the most common issues is the fact that they don’t last as long as other brands of rechargeable batteries.

There are several reasons why dewalt batteries may not perform well. First of all, their internal components aren’t designed to handle extreme temperatures or high current loads.

When it comes to these types of batteries, they need to be charged regularly. Another reason is that their lithium ion chemistry doesn’t hold up well under high temperature conditions. If your dewalt battery gets too hot, its ability to discharge will decrease significantly. A third issue is that the cells are prone to catching fire when exposed to high heat levels.

There are several ways to extend the life of your dewalt battery. First of all, don’t leave it plugged in for extended periods of time when it’s fully charged.

The other thing you can do is use a desulfating charger or a trickle charger rather than a conventional AC plug-in model.

DEWALT 20V vs 18V

Dewalt makes a 18V battery which has 3Ah cells, and the standard model which uses 1.5Ah cells.

The 18V version of the battery lasts longer and weighs more, so you need to decide how much runtime vs. weight is an issue. The 3Ah cells are physically larger, so they can’t fit in some of the smaller tools without modification.

DeWalt makes two models of drill drivers and impact drivers, DC970K-2 and DCD780. The smaller one uses the 18V battery, while the larger one uses 20V batteries.

DEWALT 20V vs. BOSCH

Bosch also makes a 20V lithium-ion system, which is cross compatible with their 18V NiCad system. The 18V batteries have a higher capacity, but they also weigh more.

The drill and driver are heavier. The 20V tools are more expensive than the 18V versions, so if you have to buy new tools anyway, you might want to go with the higher voltage.

The other big advantage for the Bosch is that the batteries charge faster and run longer per charge, which is why most professional users prefer them. The faster charging time is due to the higher voltage (20V vs.

18V), and the longer runtime is because the higher voltage means that the batteries don’t have to be made as large in order to have high capacity. The downside is that you do have to pay more attention because of the higher voltage. Do not buy a cheap knock-off charger; buy a charger made by Bosch or an authorized dealer.

Both systems have advantages and disadvantages, so it really comes down to which system is going to be the best for you. If you already own 18V batteries and are happy with them, then there is no reason for you to switch.

DEWALT 20V vs. MAKITA

Makita also has a 20V system. It is compatible with their 12V and 14.4V systems and uses the same batteries.

The big advantage is that you can use the same batteries for your drill and your driver, in addition to other tools.

The 20V batteries are not suitable for heavy-duty framing or decking, but they excel at finish carpentry or trim work.

As with the other brands, there are advantages and disadvantages to this system. The main disadvantage is that the batteries are more expensive.

The 20V battery costs about $80, where the 18V version is half that price. However, you can use the same battery in your drill and driver, so if you are doing a lot of work, this could actually save you money in the long run. You could also have spares charging while you use the first set.

The other issue for Makita is the availability of equipment. The tools are not as readily available at the big box stores, so you will need to go to a specialty store or order them online.

There are more tools being added to the 20V line every year, but they still do not have all the tools that some of the other systems have. It’s best to look at the type of work you do and decide which tool would be best for you.

BATTERY CARE

Regardless of which system you choose, proper maintenance will yield higher performance and longer life. All batteries tend to lose their charge quicker when not in use, so the best way to store them is fully charged.

Many people charge their batteries overnight and then remove them from the charger once they are done. This works fine as long as you remember to put them back in the charger once they get low.

If you don’t use your batteries for weeks at a time you should still keep them fully charged. If they sit for too long, even if they are charged, they can lose their charge very quickly when you put them back in the tool.

There are devices that will maintain the charge in the battery by putting just enough charge in to keep it from losing it’s charge.

Another thing to remember is that all of these batteries are sensitive to heat and cold. Heat will cause them to lose charge quicker, so they should not be left in a place that is excessively hot.

The same is true for cold. If you are using the tool in an area that is very cold, the batteries are more likely to die out much quicker. It is also important that you keep them away from radiators or other sources of heat.

Also remember to keep the vents clear. The battery will overheat much quicker if the vents are clogged up with dust or debris.

BATTERY SAFETY

Lithium-ion batteries are more dangerous than other types of rechargeable batteries, so extra care should be taken when charging and using them.

Due to the flammable liquid that is inside the battery, they should not be used near flame or heat and should be handled with care to prevent heavy sweating when handling. If the battery gets too hot, it could explode.

Due to this high heat, it is important to keep the battery away from your body. The plastic housing gets very hot very quickly and can cause serious burns.

Also be careful not to drop these batteries as they can leak if punctured.

If you are using the battery in a tool, be sure to read the instructions that come with the battery. Most of the tools will include safety features that will turn off the tool if it starts to overheat.

However, as with any power tool, care should always be taken when operating them. Always wear safety glasses and other protective gear as recommended by the manufacturer.
