New Energy Sources WhatsAppIndividual cell voltages differ, even with batteries of the same brand and manufacturer. A 6 volt battery might have a cell voltage of 2.2 volts and a 12 volt battery might have a cell voltage of 2.1 volts. This can however be fairly easy to read with a volt meter if one was to check. Matching amp hour ratings is much more difficult.

New Energy Sources WhatsAppHowever, a general rule of thumb is that a battery should last between 3 to 5 years. It is important to monitor your battery''s voltage regularly to ensure it is functioning properly. According to the car battery voltage chart, a fully charged car battery voltage falls between 13.7 and 14.7 volts with the engine running.
New Energy Sources WhatsAppSo far from what i read..... assuming a battery with 1.5v and 2 amp hours - Two 1.5v batteries in series will increase voltage to 3v. - Two 1.5v batteries in parallel will increase amp hours, meaning if a tiny motor current draw is 2amps, the battery will last 1 hour, but since it is in parallel now last 2 hours.. In conclusion, series increases voltage, parallel …
New Energy Sources WhatsAppTime (12A) = battery size ÷ charge rate = 65 kWh ÷ 1.44 kW = 45.1 hours; Level 2 (L2) Circling back to the power equation, we can increase the charge rate by increasing the voltage or increasing the current. To charge with adequate speed and safety, higher voltage outlets are essential. Why can''t we increase the current, instead?
New Energy Sources WhatsAppVoltage and current are the essential components of power a.k.a. the ability to perform work. To do work by means of spinning machinery requires a rotary-acting force - a torque. The rate at which the work proceeds (introduce time) and the measurement becomes of power. More power - increase either current or voltage or both.
New Energy Sources WhatsAppForward current vs forward voltage, notice how the current increases rapidly for a voltage above 3 Volt. Only 0.5 V more gives 4 x the current! This curve also changes between LEDs and over temperature. That is why it is better to feed LEDs with a current instead of a voltage.
