Your use of this website constitutes acknowledgement and acceptance of our Terms & Conditions. Here we show the contents of various batteries, which is something you cannot normally see. Primary batteries, also known as non-rechargeable batteries, tend to get overshadowed by the media attention secondary or rechargeable batteries receive.
Primaries play an important role, especially when charging is impractical or impossible, such as in military combat, rescue missions and forest-fire services. High specific energy, long storage times and instant readiness give primary batteries a unique advantage over other power sources.
Secondary batteries are typically rated at 1C; alkaline uses much lower discharge currents.
Specific energy only indicates the capacity a battery can hold and does not include power delivery, a weakness with most primary batteries.
One of the reasons for low performance under load conditions is the high internal resistance of primary batteries, which causes the voltage to collapse. Table 3 illustrates the capacity of standard alkaline batteries with loads that run typical personal entertainment devices or small flashlights. Note: Resistance can also be measured in siemens (s) units, which is equal to reciprocal ohm. To cut cost, cities often consolidate purchases and this includes bulk acquisitions of alkaline batteries.
The relationship between battery capacity and current delivery is best illustrated with the Ragone Chart.
The performance of the battery chemistries varies according to the position of the Ragone line. Primary batteries are practical for applications that draw occasional power, but they can get expensive when in continuous use.
The state-of-charge of primary batteries can be estimated by measuring the internal resistance. Do keep Battery University updated and on the web it does have a world of good information. The article is correct; alkaline batteries should not normally leak, whereas for zinc-carbon batteries, this is practically an expected behavior. The reason why zinc-carbon batteries leak is that the casing of the battery serves as the negative terminal. You can use lithium and alkaline batteries in the same device, but not on the same circuit. If different types of batteries are connected in parallel, bad things will happen as one type of battery discharges to a lower voltage than the other (or is that way initially) and tries to charge the other.
In series, it is even worse, because a good battery in series with a dead one will reverse-bias the dead one (impose a reverse polarity on it).


Even new and old primary batteries OF THE SAME TYPE should not be put in series; you should change series battery packs at the same time. I have fujitsu ah530 laptop i tried to replace the battery cell of my old battery with the same voltage and amphere cells but I failed the battery’s Positive terminal does not have any charge.
What results when an alkaline battery and a re- chargable battery are placed into a remote control (2 - AA batteries are required in the remote control)? By submitting this form, you are providing your express consent to receive electronic communications from Battery University. Heavy focus on one product over another may convince folks that primary batteries are old technology on the way out. Regulated under IEC 60086, primary batteries also service pacemakers in heart patients, tire pressure gauges in vehicles, smart meters, intelligent drill bits in mining, animal-tracking, remote light beacons, as well as wristwatches, remote controls, electric keys and children’s toys. They can be carried to remote locations and used instantly, even after long storage; they are also readily available and environmentally friendly when disposed.
It has a high specific energy and is cost effective, environmentally friendly and leak-proof even when fully discharged.
The negative is low load currents, limiting its use to light loads such as remote controls, flashlights and portable entertainment devices. These have very strict air shipping guidelines and are subject to Dangerous Good Regulations involving Class 9 hazardous material. Manufacturers of primary batteries publish specify specific energy; specific power is seldom published. The figure clearly demonstrates that the primary alkaline performs well with light load typical to entertainment devices, while the secondary batteries represented by lead acid, NiMH and Li-ion have a lower rated capacity (Rated) but are better when being loaded with a 1C discharge (Actual).
Resistance determines how well electrical current flows through a material or device and is measured in ohms (Ω). Known as penlight batteries for pocket lights, the AA became available to the public in 1915 and was used as a spy tool during World War I; the American National Standards Institute standardized the format in 1947. A city the size of Vancouver, Canada, with about 600,000 citizens would buy roughly 33,000 AA, 16,000 AAA, 4,500 C and 5,600 D-size alkaline cells for general use.
NiMH delivers the highest power and works well at high loads but it has the lowest specific energy.
Price is a further issue when the packs are replaced after each mission, regardless of length of use. Battery University monitors the comments and understands the importance of expressing perspectives and opinions in a shared forum.
I have had a couple of flashlights that were used only a few times for brief periods and six months later would have to have the batteries almost driven out and yes they were turned off. The most economical and long use between replacements was 6 stacks of 26 x CR2032 Lithium coin cell parallel with 6 x 1N4148 diodes.
While most secondary batteries are rated at a 1C discharge current, the capacity on consumer-grade primary batteries is measured with a very low current of 25mA.


The AAA was developed in 1954 to reduce the size of the Kodak and Polaroid cameras and shrink other portable devices.
Lithium Li-FeS2 has the highest specific energy and satisfies moderate loading conditions, and alkaline offers an economic solution for lower current drains. Discarding partially used batteries is common, especially in fleet applications and critical missions as it is convenient to simply issue fresh packs with each assignment rather than estimating the usage. A more accurate method is coulomb counting that observes out-flowing energy, but this requires a more expensive circuit and is seldom done.
However, all communication must be done with the use of appropriate language and the avoidance of spam and discrimination. We recommend posting your question in the comment sections for the Battery University Group (BUG) to share. About 6x capacity of Alkaline PP3 and recharging such a number of NiMH or Lithium ion in series is problematic as well as avoiding reverse charging a cell. For instance, a device that draws the bulk of its power from AAA batteries could have a coin battery on its circuit board (on a dedicated circuit) which maintains the contents of a non-volatile static RAM (NVRAM) chip.
Digital cameras with primary batteries are borderline cases — a power tool on alkaline would be impractical. In the 1990s, an offshoot of the 9V battery produced the AAAA for laser pointers, LED penlights, computer styli and headphone amplifiers.
This is the case with bicycle lights where the AA format would only increase the size of the light slightly but could deliver twice the runtime for the same cost. The test standard was based on counting the shots of a digital camera until the batteries were depleted, a test that considered capacity and loading capability of a battery.
Energy in Ah presents the available storage capacity of a battery that is responsible for the runtime; power in watts governs the load current. At a battery conference a US Army general said that half of the batteries discarded still have 50 percent energy left.
When you go to change the batteries you have to clean the crud and corrosion out before installing the new batteries.
This provides impressive readings on paper, but the results are less flattering when applying loads that draw higher currents.
A spent alkaline in a digital camera often leaves enough energy to run the kitchen clock for two years. A much more ancient example of multiple batteries are portable vacuum tube devices, which used three separate batteries: a battery for the vacuum tube heaters, another one (high voltage, 30 or more volts) for the plate, and a third battery for the grid bias!
