Energy Density: This refers to the amount of energy stored in the battery per unit of weight or volume. A high energy density is important for MWD batteries, as it allows for more energy to be stored in a compact and lightweight package.
Capacity: This refers to the amount of energy that can be stored in the battery and discharged before needing to be recharged. A high capacity is important for MWD batteries, as it allows for longer periods of operation without recharging.
Cycle Life: This refers to the number of cycles the battery can go through before its capacity starts to decline. A high cycle life is important for MWD batteries, as it allows for longer periods of operation without replacement.
Operating Temperature Range: This refers to the range of temperatures the battery can operate in without degradation of performance. A wide operating temperature range is important for MWD batteries, as they must be able to operate in high temperature downhole environments.
Self-discharge Rate: This refers to the rate at which the battery loses its charge when not in use. A low self-discharge rate is important for MWD batteries, as it allows for a longer shelf life and reduces the need for frequent recharging.
These are some of the key performance indices of lithium batteries in MWD battery packs of mud pulse inclinometers during drilling. To determine the overall performance of a specific MWD battery, it is important to consider all of these factors and how they relate to the specific requirements of the application.
