DeWalt DC9099 18 volt battery

The DC9099 and DC9096 XRP are both 18-volt batteries manufactured by one of the world’s leading power tool manufacturers, DeWalt. Both are nickel-cadmium batteries. XRP stands for eXtended Run and Performance. As the acronym suggests, they are both designed for heavy-duty use and provide longer run times than other batteries in the same range.

Quite similar in appearance, they are both portable, self-tightening, pod style, and black colored batteries. The DeWalt DC9096 battery weighs approximately 2.2 pounds. In comparison, the DeWalt 9099 is almost half a pound lighter, making it easier to transport. The DC 9096 battery measures 5.5 “in length by 3” in width by 4.5 “in height. The DC9099 battery is lighter because it is also thinner than the DC9096 by almost an inch. Compared to the battery of the previous model DW9099, these are almost half an inch thinner and half a pound lighter. The smaller and compact size of the DC9099 means it can fit in more places. small.


These two batteries, the DC9096 and DC9099, are 18 volt batteries compatible with all 18 volt battery operated tools and manufactured by DeWalt. This is a big advantage of these batteries because you can use the same battery to run multiple tools. You don’t have to spend the money to buy a different battery for each tool.

Battery capacity

By battery capacity, we refer to the maximum amount of energy that can be extracted from that particular battery. While it depends on many factors such as temperature, operating conditions, etc., it still gives an idea of ​​how much charge is stored in the battery. As claimed by manufacturer DeWalt, these batteries offer around 40% more runtime compared to other standard batteries of similar configuration.

The DeWalt DC9096 has a battery capacity of 2.4 Ah (ampere-hours). The DC9099 has a lower capacity of 1.7 Ah. Due to its higher capacity, the DC9096 lasts longer than its DC9099 counterpart. Note that a lower capacity does not mean that the DC9099 is less powerful than the DC9096. They both produce the same result and cause the same amount of work per ampere-hour. The difference is in the battery life on a single charge.


Nickel-cadmium batteries typically last around 1000 cycles, which is roughly three years with daily recharging. Likewise, the DC9096 and DC9099, being nickel cadmium batteries, can also be recharged and used once they are fully discharged. A big advantage of both of these batteries is the fact that they tend to deliver full power until the end of the discharge cycle, ensuring that maximum usage is derived from each charge cycle of the batteries. These two batteries are compatible with several DeWalt chargers. According to customer reviews, it takes about an hour for these batteries to charge to ideal temperatures of over 40 degrees and below 105 degrees Fahrenheit.

However, a downside to these nickel cadmium batteries is that once charged, they lose some of their charge over a period of time. The first day without a charger, they can lose up to 15-20% of their charge. The next day, a loss of about 7-10%. After that, the batteries lose about 1% of charge each day they are out of the charger. In addition, there is a possibility of short circuit if these batteries are stored too long without being used. This is due to the formation of dendrites or internal connections between their contacts. For these reasons, it is recommended to keep these batteries on the charger when not in use.


Since DeWalt chargers have a maintenance mode, which does not damage the battery even after it is fully charged, it is advisable to leave the battery on the charger to ensure that it goes through the battery modes. ‘equalization and maintenance. In addition, it is ideal to place the battery for at least 8 hours on the charger to allow full recharging on each cell. This prolongs the life of the battery.

It is also crucial that the batteries are charged under optimum temperature conditions. Failure to do so may result in permanent damage to the batteries, leading to a reduction in their autonomy.

Overall performance

Both batteries perform exceptionally well. Although there have been few complaints from customers about the short run time of these batteries, the general opinion seems favorable. DC9096 is recommended for longer run time with less frequent charging required, compared to DC9099. However, if portability is the key feature you’re looking for, the lighter, more compact DC9099 is a better option.

A big advantage of these two batteries is that they do not heat up when charged like other batteries. Also, since DC9096 and DC9099 are nickel cadmium batteries, they can perform better in extreme temperatures than lithium ion batteries.

The biggest drawback of these batteries is the high self-discharge rate. However, this snag can be circumvented by allowing the battery to remain on the charger. Another disadvantage of these batteries is the possibility of a reduction in their autonomy thanks to the “memory effect”. However, it is rarely seen in the daily practical use of these batteries.


Once these two batteries are at the end of their useful life, they can be taken to DeWalt service centers instead of throwing them away. Their manufacturer, DeWalt is a member of the Rechargeable Battery Recycling Corporation and they aim to recycle used batteries to reduce the dangerous impact on the environment.


These two DeWalt batteries, the DC9096 and DC9099 are covered by a 3 year limited warranty. Plus, both are also backed by a 90-day satisfaction guarantee and a 2-year free service contract.


Choosing between these two machines is difficult because the choice boils down to two things. Size vs runtime. The DC9099 is a bit smaller than the DC9096 and weighs about ½ pound less. This is important when you consider the fatigue that the extra weight could cause to your hand over time. But the DC9096 has a longer run time. If we had to choose between the two, we would definitely go with the DC9099 as the extra range you get with the DC9096 probably wouldn’t make up for the difference in dimensions and weight. Of course, you can decide to go the other way around, but that wouldn’t be a bad choice either.
