Results across four studies indicate that, overall, consumers perceive objective price-quality relationships with only a modest degree of accuracy. However, findings also suggest that the accuracy of consumers'' perceptions is moderated by product type; that is, price-quality perceptions are more accurate for nondurable products than for durable products. The authors …

The relationship of price and quality is at the heart of the model described by Philip Kotler. He sees three levels of price – high, medium and low. He also recognises three levels of quality – high medium and low. The combination of these levels of price and quality result in nine pricing strategies. These are shown in the figure below.

That is, for the participants in their rational assessment in terms of the relationship between price and quality, the quality of the premium product was only recognized and valued by 25% of the participants in the experiment. Our research in practical terms goes deeper into the concepts of price image, price consciousness, and price perception. The perceived-value represents …
The relationship between voltage and charge is at the heart of lithium-ion battery operation. As the battery discharges, its voltage gradually decreases. This voltage can tell us a lot about the battery''s state of charge (SoC) – how much energy is left in the battery. Here''s a simplified SoC chart for a typical lithium-ion battery:
I''m thrilled to share my passion and years of experience in the world of batteries with you all. You might be wondering why I''m so excited about battery capacity measurement. Well, let me tell you, it''s not just because I''m a …
A ratio between 18 and 26 is observed between the VI of GHI timeseries and WVM-smoothed timeseries. Similarly, the PV power drop of the isolated scenario is reduced by up to 60% between the pyranometer and the WVM-smoothed timeseries, which remains consistent with [20] where a 40% variability reduction was estimated for the same timescale.
A Price Quality Matrix is a strategic tool used by businesses to analyze and visualize the relationship between price and quality across different products or services in a market. This two-dimensional graph plots price on one axis and quality on the other, allowing companies to map their offerings against competitors and identify potential market …
Design/methodology/approach. Using data from consumer reports objective-test results of 14,476 durable products available in the US the authors identified product categories containing both national and PL brands; constructed relative price- and quality-indices for each category; calculated price and quality differentials for each category then modeled the relationship …

Some batteries are known as dual-purpose batteries and are designed to be both starting batteries and deep-cycle batteries. The main difference between these two types of batteries is their cold-cranking amps (CCA) rating. A starting or dual-purpose battery will have a higher CCA than a deep-cycle battery.
