Battery Terms

Amperage / Amp Hours (Ah)
Represents the amount of energy a battery can hold. This measurement helps determine how long the battery will power the equipment it is used in. Generally speaking, the more 'Ah's' the longer the run time.

Capacity
The amount of energy a battery can store. Measured in Amp Hours or Milliamp Hours, this is the length of time the battery can supply the required voltage.

Cell
A single battery canister. Usually grouped together with other cells to form battery packs of different voltages and amperages.
Example: one NiCD cell is 1.20 volts therefore six cells packaged together makes a 7.2 volt battery pack.

Charge
The process of putting energy into a battery.

Conditioning A Battery
A process that utilizes a series of heavy discharges and recharges on a battery to assure optimum performance.

Cycle Life
The amount of times a battery may be charged and discharged. Every time a battery is charged and discharged it uses one cycle.

Discharge
The release of energy by the battery.

Memory
The term used to describe the capacity loss and subsequent voltage drop in a battery due to constant or repetitious charging and incomplete discharging. This results in a loss of run-time.

Milliamp Hours (mAh)
Refers to battery capacity. 1/1000 th of an amp.
Example 1.8Ah = 1800Mah

Rated Capacity
Measured in 'Ah' or 'mAh' capacity is determined by the cell manufacturer. This number is then used to determine run time and is also in warranty policies.

Self-Discharge
The process of a battery releasing its energy without being used. This can occur by just sitting on the shelf. Most batteries self-discharge about 1 to 2 percent each day.

Voltage
Units of measuring electrical current, all batteries are rated in volts DC. (Direct Current). This determines how much energy is needed to power your equipment, yet heavy discharge.

 

Batteries

What is a Standard Battery?
A Standard battery is a battery which has been manufactured to be charged with low currents. It should be charged using a Standard Charger.

What is a Rapid battery?
A Rapid battery is a battery which has been manufactured to be charged with high currents. It should be charged using a Rapid Charger.

What is a Battery Insert?
It is a battery pack without the hard case. They come ready to be installed in a hard case battery pack. Buying a battery insert instead of a complete battery pack represents a significant savings. Unfortunately, battery inserts are not available for all W & W battery packs. Please check our catalog or call for information.

What is memory effect?
Also called voltage depression. This phenomenon happens in the Ni-Cd batteries. The battery “remembers” how much energy was extracted in previous discharges and try to accept that amount of energy only in the next charge. This reduces the available capacity of the battery.

Memory effect is actually a gradual change in the crystalline structure of the battery’s cell plates. This change is often accelerated by repeatedly recharging before fully discharging. Over time an alloy derivative of nickel and cadmium forms inside the negative electrode. Because of its chemical composition, this alloy has a lower voltage potential than the original plate material. If a battery is continually recharged before being fully discharged, the alloy will continue to develop and will progressively reduce the level of energy the negative electrode is capable of retaining. This reduces the available capacity of the battery.

What is formatting a new battery ?
It is the process a new battery has to go through to make sure its electrolyte can use all its capacity to store energy. This process consists of 3 or 4 charge-fully discharge cycles. W & W Analyzer has the “Conditioning Mode”, which can format the battery in less time than other analyzers.

 

Battery Types

Nickel Cadmium. (NiCD) NiCd (NiCad or Nickel Cadmium) batteries are prone to what’s called the “memory affect” They like to be fully drained before being recharged. When they’re charged often without being run down first, they develop a “memory” which in time lowers their charge capacity and ultimately reduces their overall life expectancy. They are slightly less expensive than NiMH batteries and can be stored for much longer periods of time on a shelf while maintaining a relatively high charge capacity.

Nickel Metal Hydride. (NiMH) NiMH (Nickel Metal-Hydride) batteries are not nearly as prone to the “memory affect” and can therefore be charged at any time. They do not get as many charge cycles in their lifetime however, but your long-term battery life might still be better if you typically use NiCD batteries and don't wait until the battery has been drained down before recharging. NiMH are generally significantly higher in capacity (up to 30% higher per charge than NiCd batteries of the same physical size), which means they will last longer per charge, but are not great being stored for periods of time longer than 3-4 weeks. We recommend using NiMH batteries when available for agencies that don't have the luxury of running a battery down before recharging (police, fire, EMS, etc.) but NOT as 'emergency backups' that are left on a shelf until they are needed.

NOTE: While NiMH batteries *can* be charged in a NiCd-ONLY charger, it is not recommended. NiMH batteries run very hot, and NiCd-ONLY chargers lack the circuitry to shut down charging on a NiMH battery, which if left unattended for too long a period of time, the battery could experience melting, venting, bursting or fire. We've never seen it happen with batteries and chargers that were in good condition, but why take that chance. (By the way, we sell multi-chemistry chargers if you're interested)

Lithium Ion. (LION) The newest rechargeable battery chemistry available. Lithium Ion is not affected by the 'Memory Effect'. It can deliver the same capacity and run time in a smaller, lighter pack. The chemistry is most popular in cellular and laptop products.

NOTE: If you do not have a charger designed to charge a Li-Ion battery, then Li-Ion is not even an option for you. Your charger MUST specify that it is a tri-chemistry charger or that it can specifically charge Li-Ion batteries.

Sealed Lead Acid (aka: Gel-Cell) Primarily found in emergency lighting and burglar alarm applications. Designed for steady, constant charging with an infrequent.

 

Chargers

What is MasterCharger 6?
It is W & W Manufacturing Company's Rapid (Fast) charger with six stations (for six batteries). MasterCharger 6a can charge six different batteries simultaneously,with different voltages and capacities, Nickel-Cadmium, Nickel-Metal Hydride, Lithium Ion.... It does not make a difference. In addition, you decide which battery you wish to charge. You can charge batteries manufactured by Motorola, Yaesu/Vertex, Kenwood, Icom, Standard Maxon, Kyodo, Relm, etc. You can mix different manufacturers' batteries and if at later date, if so desired, you can change one or all six positions to accommodate other manufacturers' transceivers.

Note: This product has been discontinued, but will still be supported.

What is MasterCharger 5/10?
MasterCharger 5/10 can charge 5 or 10 different batteries simultaneously, with different voltages and capacities, Nickel-Cadmium, Nickel-Metal Hydride, Lithium Ion.... It does not make a difference. In addition, you decide which battery you wish to charge. You can choose batteries manufactured by Motorola, Yaesu/Vertex, Kenwood, Icom, Standard Maxon, Kyodo, Relm, etc. You can mix different manufacturers' batteries and if at later date, if so desired, you can change one or all positions to accommodate other manufacturers' transceivers.

What is a Rapid Charger?
Also called Fast-Charger. It usually charges the battery in about one hour. Since it uses a high current to charge the battery, it monitors the battery during charge. When the battery is fully charged it switches to Trickle charge to compensate for the self discharge of the battery. The battery can stay on the charger until it is needed.

What is a Standard Charger?
Also called Slow-Charger. It usually charges the battery overnight (typically 12 to 16 hours). It  does not monitor the battery during charge because it applies a small current to the battery. When battery is fully charged, it should not stay on the charger more than few days.

What is a Trickle Charge? 
It is the phase of the rapid charging process, where the battery is charged with a small current to compensate the self discharge of the battery. The current rate used in this phase is called Trickle current. W & W MasterChargers and W & W Analyzers use a 40 ma, 50 % duty pulse current as Trickle current.

What is a Universal Charger (UC1 and UC6)?
A true universal charger will charge all major radio manufacturers' batteries. If the radio utilizes all three chemistries, Nicd, Nimh or Li-ion, you will only need one adapter cup to accomplish charging the various batter chemistries. What makes the UC SERIES even more unique is that without any tools you can simple replace the adapter cups and the Charger will then charge another manufacturer's radio batteries. UC1 can be used in a vehicle with the use of a car cord.
