Any Nerf connoisseurs who use a blaster that requires batteries to run such as the fully automatic Titan CS-50 needs to be mindful of the type of battery it uses and its capacities to not find themselves in a situation where they are unable to use the blaster because the battery had run out. Naturally, what batteries does the Nerf Elite Titan take?

Types of Batteries

The Nerf Titan CS-50 uses 4 separate D batteries to power its motors which makes the flywheel launching system internals fire darts. However, a little prior knowledge of batteries goes a long way for users to choose the perfect kind of battery for their battery-powered blasters. A battery is a source of electrical energy, which is provided by one or more electrochemical cells of the battery after the conversion of stored chemical energy. Batteries can be divided into two major categories Primary Batteries and Secondary Batteries.

Primary Batteries

A Primary Battery is a disposable kind of battery. Once used, it cannot be recharged. Secondary batteries are rechargeable batteries, once empty, they can be recharged again. This discharging and recharging can happen many times depending on the battery type. They are sometimes called single-use or throw-away batteries because they have to be discarded after they run empty as they cannot be recharged for reuse. Primary batteries are able to produce current immediately on assembly. Batteries that are disposable are meant to be used once and discarded.

These are most commonly used in portable devices that have a low current drain and are only used intermittently or are used well away from an alternative power source. Such as in alarm and communication circuits where other electric power is only intermittently available. Disposable primary cells cannot be reliably recharged because the chemical reactions are not easily reversible and active materials may not return to their original forms. Battery manufacturers also recommend against attempting to recharge primary cells 

Examples of primary batteries are alkaline batteries, mercury batteries, silver-oxide batteries, and zinc-carbon batteries, whereas lead-acid batteries and lithium batteries fall into the group of secondary batteries.


The lowest-cost primary cell is the zinc-acidic manganese dioxide battery. They only have very low strength, but they have a long shelf life and are well suited to remote controls and clocks.


The most commonly used primary cell is the zinc-alkaline manganese dioxide battery. They provide more power-per-use compared to carbon-zinc and secondary batteries and have an excellent shelf life. 


Lithium batteries provide performance benefits well beyond traditional aqueous electrolyte battery systems’ capacities. Their shelf life can be well over 10 years and they can operate at very low temperatures. Lithium cells are mainly used in small formats (coin cells up to about AA-size) because bigger sizes of lithium batteries are a safety concern in consumer applications. For example, bigger size D lithium cells are only used in military applications. 

Silver oxide 

These batteries have a very high energy density, but due to the high cost of silver, they are very costly. Therefore, silver oxide cells are mainly used in a button cell format for watches and calculators 

Zinc-air cells

These batteries have been the standard for batteries for hearing aids. They have a very long run time because they only store the anode material inside the cell and use the oxygen from the ambient air as a cathode.

Secondary Batteries

They are mostly called rechargeable batteries because they can be recharged for reuse. In the discharged state, they are usually assembled with active materials. Rechargeable batteries or secondary cells can be recharged by applying electric current which reverses the chemical reactions that occur during its discharge. Devices that the appropriate current to cells are called chargers or rechargers.

Rechargeable Alkaline Batteries

Secondary alkaline batteries are the lowest cost rechargeable cells and have a long shelf life while typically are useful for moderate-power applications. However, their cycle life is less than most other secondary batteries but they are still a great consumer’s choice as they combine the benefits of the popular alkaline cells with the added benefit of a re-use after charging. They have no toxic ingredients and can be disposed of in regular landfills if local regulations allow so.


Secondary Ni-Cd batteries are rugged and reliable. They exhibit a high power capability, a wide operating temperature range, and a long cycle life, at the cost of having a low run-time per charge. They have a self-discharge rate of approximately 30 percent per month. They contain about 15% toxic, carcinogenic cadmium and have to be recycled and if not done so the environment can be polluted.

Nickel-Metal Hydride

Secondary Nickel-Metal batteries are an extension of the old-fashioned NiCd batteries. They provide the same voltage as the NiCd batteries but offer at least 30% capacity. They exhibit good high current capability and have a long cycle life. The self-discharge rate or the rate that it discharges without usage is higher than NiCd at approximately 40% per month. Thus they are meant for heavier usage compared to NiCd batteries because of the higher capacity and higher self-discharge rate. Nickel metal cells contain no toxic cadmium, but they still contain a large number of nickel oxides and also some cobalt, which are known human carcinogens and should be recycled. 


The latest breakthrough in rechargeable batteries is the secondary Li-Ion battery. They are at least 30% lighter compared to Nickel-Metal Hydride batteries and provide at least 30% more capacity as well. They exhibit good high current capability and have a long cycle life, thus their applications in smart gadgets. The self-discharge rate is also better than NiMH at approximately 20% per month. Overheating however will damage the batteries and could cause a fire to occur. Li-Ion batteries contain no toxic cadmium but they still contain cobalt oxides or nickel oxides which are human carcinogens and they must be properly discarded at a nearby recycling facility. 


To conclude, which kind of battery is the best suited to be used inside the Titan CS-50? In my opinion, going to the nearest store that has a D size alkaline battery is not the best option in my opinion. While it is convenient as parents or nearby adults would not need to worry about recharging and would simply need to purchase another set of batteries if the ones bought in the first place are empty. However, users also need to consider that rechargeable secondary cells are also a much more economically wise option because no additional batteries are required to be bought in any time soon, and recharging the batteries is much easier than going out to the store to purchase a new set. I believe that the rechargeable alkaline, lithium, or lithium-ion is the most considerate choice. However, adults need to remind the kids to not tamper with the battery as they will contain carcinogenic material.
