Word Description
R resistance
Rapid Charge The charging of a battery, typically a NiCad, to its capacity in a short period of time
Rapid-Charge Battery A battery pack that is designed to accept a high amount of current in a short amount of time, such as a radio-control battery
Rate Sensitivity Typically refers to battery performance under various discharge loads with operating voltage being the defining characteristic
Rated Capacity (Dry Cell) The average capacity delivered by a cell or battery on a specified load and temperature to a cutoff voltage, as designated by the manufacturer. Rated capacity is usually determined by an accelerated test approximating the cell or battery's capacity in typical use.
Rated Capacity (Flooded) The CCA, RC or amp-hours that a battery can deliver at a given rate of discharge, end voltage and temperature. These ratings are often displayed on the outside of the battery
RC reserve capacity
Rechargeable Battery A cell or battery capable of being recharged. Refers to secondary batteries
Recharging See charging
Recombinant The process in which the oxygen formed at the positive (+) plate diffuses to the negative (-) plate, reacts with the lead and suppresses water loss. In a recombinant (immobilized electrolyte) chemistry battery, gassing is recombined within the sealed battery so that water addition is unnecessary
Reconditioning See Conditioning
Rectifier Device that changes alternating current to direct current
Rectify To convert alternating current into direct current
Reserve Capacity (RC) BCI defines it as "the number of minutes a new, fully-charged battery at 80F (27C) can be discharged at 25 amps and maintain a voltage equal to or higher than 1.75 volts per cell" (i.e., 10.5 volts for a 12-volt battery). This rating represents the time the battery will continue to operate essential accessories in the event of a charging system failure.
Resistance (R) The opposition to the free flow of current in a circuit. Resistance is measured in ohms. See also Internal Resistance
Resistor A device, with electrical resistance, that is used in an electrical circuit for current control and efficient operation.
Reversal See Reversed Polarity
Reversed Polarity The changing or reversing of the normal polarity of a battery, which commonly occurs when battery cables or charging cables are connected backwards
Ri internal resistance.
