I copied this from the very useful and relevant webpage on LED driving - here and they in turn copied it from an LM317 data sheet. The off list query said. You mentioned a way by …
How to judge whether the car battery needs to be replaced? Old driver: Just look at these 4 points! In fact, we all know that the car needs further maintenance after buying it back, but for many times, if we do not maintain in place, then some of the conditions of the battery are not noticed at all, so We also need the supply of batteries for many parts of the car.
• Specific Energy (Wh/kg) – The nominal battery energy per unit mass, sometimes referred to as the gravimetric energy density. Specific energy is a characteristic of the battery chemistry and packaging. Along with the energy consumption of the vehicle, it determines the battery weight required to achieve a given electric range.
Empirically, we study the new energy vehicle battery (NEVB) industry in China since the early 2000s. In the case of China''s NEVB industry, an increasingly strong and complicated coevolutionary relationship between the focal TIS and relevant policies at different levels of abstraction can be observed. Overall, we argue that more research is needed to …

The way the power capability is measured is in C''s.A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A.The amount of current a battery ''likes'' to have drawn from it is measured in C.The higher the C the more current you can draw from the battery without exhausting it prematurely. Lead acid batteries can have very high C values (10C or …
1. Measure voltageMeasure the battery voltage with a battery meter or multimeter. Under normal circumstances, the no-load voltage of the battery is around 13 volts, the full-load voltage is generally no lower than 12 volts, and the starting voltage should not be lower than 9.5 volts. If the battery voltage is too low, it may be difficult or impossible to start the …
