9V Batteries:
The Quick And Easy Guide For Optimized Devices
9V batteries are one of the "big 5" or highly in-demand batteries because of the many applications or devices it can power up. Each 9-volt battery is literally described as a rectangular prism cell having rounded edges and polarized snap connector at its top. It has product dimensions of approximately 46.40 mm to 48.50 mm in height; 25.0 mm to 26.50 mm approximate length and the width ranging from 15.0 mm to 17.50 mm. It is first used in transistor radios. This is the reason why some manufacturers still refer to nine-volt batteries as transistor batteries.
9V Batteries:
Types And Chemistries To Consider
9V batteries come in two basic types. These are primary 9V batteries and the 9-volt rechargeable batteries. The primary ones have different chemistries or composition. Rechargeable batteries are also made of various chemical compositions with slight differences in some features. Primary cells are either alkaline batteries, Lithium, zinc-air, Zinc chloride, silver oxide, and other variants. On the other hand, rechargeable batteries are made up of such chemistries as rechargeable alkaline batteries, Lithium-ion, Lithium Iron Phosphate (LiFePO4), Lithium Manganese Oxide (LiMn2O4), Lithium Titanate (Li2TiO3), Lithium Nickel Manganese Cobalt Oxide
(LiNiMnCoO2), Lithium Cobalt Oxide (LiCoO2), Nickel Cadmium (NiCad), Nickel Metal Hydride (NiMH), Lead Acid. Different chemistries have different characteristics. This affects the performance and compatibility with your chosen devices.
Primary Batteries
Primary batteries are mostly composed of 9V lithium and alkaline batteries from such brands as Energizer, Duracell, Procell, Varta, Ansmann, Ultralife, Stryka, Fujitsu, Panasonic, Master, MI Battery Experts, Philips, GP, Vinnic, Kaba Ilco Unican, and many others. Popular and long-lasting 9V alkaline batteries include Energizer MAX Plus Advanced 9V, Energizer MAX 9V, GP29A 9V, Ansmann 9V, Varta High Energy Alkaline Batteries 9V, Duracell Coppertop 9V, Panasonic 6LR61T Industrial Grade 9V, Fujitsu Universal Power 6LF22 9V size alkaline battery, MI 9V Alkaline batteries, A136 9V Alkaline Battery, and 9V 120mAh Alkaline Battery. Long-lasting Lithium batteries include Ultralife 9V Lithium battery, Heartstart FRx-OnSite-HS1 Battery (M5070A), and Ultralite 9V Lithium Smoke Alarm Battery.
Primary 9V batteries are usually sold in blister packs either solo or a single piece and in packs of 2, 4, or even 10. These are also available in boxes of 12, 24, 28, or bigger boxes of 72 or more and have various options labeled as bulk batteries. These have varying prices based on brand, bulk pricing plans, and other specific battery requirements. Primary alkaline batteries last for four hours while Lithium disposable batteries last as twice as that of alkaline. This means that Lithium primary batteries can last for up to 10 hours or even more as some expensive brands claim.
Rechargeable 9V Batteries
Rechargeable 9V batteries come in two size variations. These are the PP3 and PP9. The nine-volt battery rechargeable size variations exist to allow higher capacity charge capacities, whenever required. Long-lasting rechargeable 9V batteries include Ansmann 9V E Type 300mAh NiMH LSD, VARTA Ready 2 Use 200mAh 9V Ni-MH Battery, and many other popular products. Energizer has a wide range of 9V rechargeable batteries. Eneloop, Power, Tenergy, and other leading brands also manufacture rechargeable batteries that are even sold with chargers in a pack. Some rechargeable 9V batteries are sold in blister packs of one or more cells. Others are also available in stores with their respective chargers so consumers will find it more convenient to have these nine-volt battery chargers ready whenever their initial charge wears off. Another option is that you can buy 9V batteries in bulk. Depending on the manufacturer, direct supplier, or battery wholesaler, these bulk batteries come in various bulk pricing plans to suit any specific battery requirements and aesthetic preferences.
Common Nine Volt Battery Applications
A nine-volt battery, either disposable or rechargeable, is usually used in smoke alarms, smoke detectors, walkie-talkies, transistor radios, test and instrumentation devices, medical batteries, LCD displays, and other small portable appliances. 9V batteries are also ideally used in patient monitors, monitoring devices, emergency beacons, data recorders, surgical lighting, and other medical devices, equipment, and instrumentation. 9V batteries are not just commonly used in the healthcare industry but are also popular in manufacturing, contracting, commercial properties, education, hospitality, or any other sector from a global perspective.
Other 9V Battery Facts Explained
9V batteries are not exactly 9V in voltage. A nine-volt battery is standard battery size and shape, not the actual voltage or nominal voltage itself. Some of these batteries have working voltages ranging from 6.5V - 8.4V. Only 9V alkaline batteries have a voltage that is exactly 9 volts. In the case of rechargeable batteries, the voltage may come even lower or higher than this range. This depends on the 9V cell chemistry. Rechargeable 9V batteries may have nominal voltages of 7.2V, 7.4V, 8.4V, 9.6V. The difference in voltage also varies on the 9V battery model.
9V BATTERIES
DIFFERENCES IN PERFORMANCE AND OTHER ISSUES
9V batteries that have different working voltages also have some minor differences in performance. A 9.6V NiMH nine-volt battery is rare but provides good performance and runtime. A working voltage of 9.6V is achieved using eight cells with 1.2V each.
The 8.4V NiMH battery will also do well but not so good with power-hungry or high drain devices compared to 9.6V. This working voltage is achieved by putting together seven 1.2V cells.
9V cells with either NiMH or lithium chemistry also performs better at 7.2V working voltage. This working voltage is achieved by using two 3.6V cells. Li-ion batteries have nominal voltages of 3.6V and 3.7V.
Rechargeable 9V batteries usually come in two options. These are NiMH and Lithium. Lithium batteries double the NiMH capacity. NiMH batteries last for about four hours with the rechargeable Lithium lasts for 7 to 7.5 hours.
9V batteries come with a special charger as these are not compatible with universal chargers or any other battery charger. Most 9V batteries are sold in the market along with corresponding battery chargers in a pack. One advantage of getting these battery packs with chargers is that it can save you time and helps to optimize your batteries as well as the performance of your devices or equipment since these are compatible products.
DIY 9V Battery Pack
Get a battery holder that can hold up to eight cells. Place 8 NiMH batteries into it. Finally, attach a 9V battery connector to the loaded holder. Now, you have the DIY 9V battery pack. Your very own 9V battery pack offers more run time compared to the standard size 9V battery.
The Bottom Line
9v batteries are used in many applications requiring a greater amount of power than other devices. A nine-volt battery pack usually comes with a charger that makes it easier for consumers to instantly charge anytime they need to. These standard cells serve various applications and devices. As with any other battery size, it is important to note the differences in chemistries that affects cell performance and other features.
FREQUENTLY ASKED QUESTIONS
When Is a 9V Battery Dead?
The answer here depends on the device you are powering up. Different devices have different voltage requirements. In the case of 9V batteries used in smoke alarms, smoke alarms start functioning between 6V to 7.6V. If the voltage falls under 6V for this device, then a particular 9V battery is considered dead.
Can 3.7V Device Run-Off 9V Battery?
Some devices are indeed voltage sensitive. So, if you have a 3.7V device and try to use 9V batteries on it for power, it can fry your device. The concept here is so simple. A 9V battery is different from a 3.7V battery or 3.7V battery-powered device. Using 9V batteries on 3.7V devices is more dangerous in electronic devices while it is less dangerous on motors.
