I
Initial Charge
Many battery manufacturers recommend to slow charge a new NiCd battery for 24 hours before use. A slow charge also helps to bring all the individual cells within a battery pack up to an equal charge level because each cell may have self-discharged to different capacity levels during storage.
Internal resistance
Resistance to electrical current inside a cell or battery pack.
IR Drop
A drop in voltage associated with the electrical resistance (R) of a battery and battery cables and current flow (I). The voltage drop is the product of the current (in amperes) and the resistance (in ohms).
IUI Charge Algorithm
A charge algorithm for some valve regulated lead-acid batteries where an equalize charge stage is added to the traditional 3-Stage Charge Algorithm between the absorption and float stages. Reduces time to fully charge battery.
