During regular use, batteries charge and discharge countless times. A common mistake most users make with their batteries (lead-acid or Lithium) is overcharging and over-discharging, also known as deep discharge. Tubular Lead Acid Batteries are charged with the help of an inverter/UPS/home UPS.
Tubular Lead Acid Batteries are charged with the help of an inverter/UPS/home UPS. The manufacturer preprograms these chargers to cut off the charging process once the battery has attained the required voltage level, say 14.4V.
Yes pin voltage in excess of Vcc voltage will cause damage, so 5vdc limit on 5 volt boards and 3.3 volt limit on boards running a 3.3vdc. Your choice, but you might want to check battery manufacture data for safe discharge voltage to be sure. -i was thinking a voltage divider could be used to cut the battery voltage in half Yes, a typical solution.
Usually, the low voltage cut-off (LVC) for a 12V battery is 10.5V. It means the battery will stop running the load when it comes down to 10.5 V. This LVC can be set even higher, such as 11V, to improve the battery’s life and reduce all chances of deep discharge. The higher the LVC, the better the battery’s life, whether lithium-ion or Lead acid.
No it do not. :' ( If you read datasheets of lead-acid battery charger ICs (e.g.; BQ2031 and BQ24450), you will see that they have internal voltage references of 2.2V and 2.3V. They are for taking feedback from 1-cell battery (though multiple cell batteries can be connected by "fooling" the IC with a voltage divider network).
A battery’s Low voltage cut-off (LVC) is the voltage level at which the charger disconnects the load from the battery. It is when the battery stops powering your fans, lights, refrigerators, and other loads in the house.
