ELI5: Why are batteries inserted in opposite ways?
So, if a device needs more voltage, they keep adding batteries until they have enough. Likewise, if a device (like a radio controlled car) needed the most possible amperage, they keep adding batteries.

Why do batteries with the same voltage have different currents?
Current depends on Voltage". So, if the voltage is high, current would be high. Agreed; (I=V/R) True, if you''re asking about resistance. But, you''re asking about a (non-ideal) voltage source - a battery. The voltage to current relationship of a battery depends on the chemistry, temperature, etc. Cells and batteries are not resistors. Now, it is the case that a first approximation of a …

Why are lithium-ion batteries stored at 50% voltage …
In short, lower is better, but there is a limit. Voltages both too low (below 2.7V) and too high will damage Li-Ion cells, and they are best kept at "happy medium" levels. Also, there is self-discharge (5% in 24h, then 1–2% …
Do batteries in series equalize charge
Lithium batteries even have separate ''equalising wires" connected to each cell, so the charger can adjust the current individually. Worse than charging an unbalanced pack is discharging it. The empty cells will be forcibly drained far past their safe minimum voltage, possibly until they are inverted. This will cause permanent damage, even if done at low current. …
Why do batteries fail? | Science
Performance degradation through battery lifetime is common to all battery technologies and can evolve at different rates, depending on operation conditions (temperature, charge/discharge rate, and voltage operation limits). Still, aging processes are ultimately rooted in chemical reactions between battery components and are thus technology-specific. These …

Why Proper Cell Balancing is Necessary in Battery Packs
Most typical battery chargers detect full charge by checking whether the voltage of the entire string of cells has reached the voltage regulation point. Individual cell voltages can vary as long as they don''t exceed the limits for overvoltage protection. However, weak cells (ones with lower capacity / higher internal impedance) tend to exhibit higher voltage than the rest of the series …

Battery aging phenomena evolve at substantially different rates depending on storage or usage conditions (temperature, charge/discharge rates, and voltage operation limits) and are specific to each battery chemistry. The study of the origin of such processes is important for battery calendar-life predictions, but this research is complex to carry out because it involves field trials …
electricity
When it detects an excessively low battery voltage it turns itself off. That circuit stays in the "off" state until voltage is completely removed from the circuit. When you operate your camera, the current required by your camera varies according to what you do with it. So the typical current required by your camera is less than the maximum current. Theoretically batteries are …

One aspect of solar lighting that you may need to replace or troubleshoot is the batteries, and I often see these 9 questions come up in forums or video comment sections:. Why Do Solar Lights Need Batteries?
battery charging
I have noticed that AA (or AAA in that case) rechargeable batteries are always of nominal 1.2V while non-rechargeable have nominal voltage of 1.5V. This works just fine in some cases, e.g. when the voltage requirement refers to just one battery and to a not really demanding load such as a tungsten lamp. In the latter case only the lumens would ...

Why Does Battery Voltage Drop Under Load . Batteries are like people in that they get tired as they work. The chemical energy in the battery is converted to electrical energy, and this process is not 100% efficient. That''s …
Why do rechargeable batteries deplete so quickly compared to …
An alkaline (non-rechargeable) battery has a nominal voltage of 1.5V. It will start at 1.59V at 100% and drop to 1.20V at 10% (with zero load, it will be lower with higher loads). An NiCd or NiMH (rechargeable) battery has a nominal voltage of 1.2V. NiMH batteries will start at 1.4V and drop to 1.1V. NiCd are more stable around 1.2V.
amperage
It is an optimization problem. You can optimize batteries for capacity and for ESR (which limits the maximum current). But unfortunately, these two are coupled in complex ways and there is an upper limit how much you can decrease the ESR while increasing the capacity, and vice versa (much simplified to the point its not accurate anymore: for high …
