AI Customer ServiceUnderstanding 12-Volt Batteries and Power Supplies. Before diving into the specifics of charging, it''s essential to understand what a 12-volt battery and a power supply
AI Customer ServiceWhen the power supply is not connected to a circuit, there will be no current flowing, therefore: V = E - 0 x r . V = E . i.e. the e.m.f voltage, is equal to the open circuit terminal voltage of the power supply. The internal resistance can be determined, by connecting a circuit of known resistance and measuring the current that flows.
If the device is running off battery, the output voltage of the battery will be increased by circuitry to run the device at the required level, however the voltage of the batteries themselves decreases as they loose power (and this is how the amount of charge left is calculated) When you have a power supply, it needs to provide the correct voltage.
When you have a power supply, it needs to provide the correct voltage. If there is enough current it will run the computer. If there is more current available then the computer requires to run it will charge the battery with the excess, and if it's not enough, the battery will provide power to top up the difference.
If a laptop, cell phone, or tablet will not be used for a long time, charge the battery to 50%, turn the device off, and remove the AC power supply (adapter). Recharge the battery every three months to 50% to prevent battery damage by over-discharge due to long-term storage without using.
If the charging source cannot deliver enough current to supply the load, the battery will discharge, providing the extra current required. The battery will switch between charging and discharging automatically as the load demand and charge source capability vary.
To extend battery life, when a battery maintains 90%-100% power after being fully charged, the system may not recharge due to battery protection mechanisms. Note: A battery’s charge initiation capacity (%) is usually set between 90%-99%. The actual value will differ by model.
