$begingroup$ The charge voltage depends on the battery chemistry. Some lithium ion batteries are charged to 4.2v, some to 3.6v, etc. And the battery voltage will vary with the current charge state - less charge means less cell voltage, but the relationship is not linear (quick drop from completely full, flatter plateau for a while, quick drop again when getting low).
Emergency Power Systems provide automatic backup power in the event of normal power loss.

- **Stable Power**: The power supply must provide stable voltage and frequency, as variations can affect the performance and longevity of the fire pump motor. - **Protection from Transients**: Surge protection devices should be installed to protect the fire pump controller and motor from electrical transients and spikes.
To compute the amps of a battery with any voltage, use this simple formula: POWER = VOLTAGE × AMPS (CURRENT) So, AMPS = POWER ÷ VOLTAGE (e.g. 6V) In that vein, we can also see clearly that the wattage of a 6V battery can be computed easily from the formula (power or wattage = voltage × Ah). For a 6V battery, we get. Wattage = 6v × 100Ah
Battery Backup Time – How Long Will The Uninterruptible Power Supply (UPS) Run When The Power Goes Out? A lot of people are confused by this and think that the capacity rating of the battery backup UPS (for example 1 kVA / 700 Watt) determines the amount of battery backup power time they will have during an outage. IT DOES NOT.
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. The 6 volt battery might really be a 5.2 Ah, while the 12 volt battery might be 5.5 Ah.
