Voltages: Minimum, Maximum, Storage, & ReplacementUpdated 3 months ago

Minimum, Maximum, Storage, & Replacement Voltages for the 11.1v battery

The original Home battery is a 3S 11.1v battery 

  • Maximum capacity voltage is 12.6v (this number slowly declines over time - this is normal) 
    - the last phase of charging is balancing the voltage between the cells inside the battery pack - this is important to battery health & longevity.
  • Minimum voltage is 9.6v - the voltage should not be allowed to drop below this.
  • Storage voltage is 11.4v for storage or if it won't be used within 3 days 
    • If you store the battery long term - bring the battery out of storage every 3 months to charge fully and discharge back to storage voltage to continue storing.  
  • Replace the battery once the maximum capacity reaches 80% - which is 10.08v

Using the battery until it drains below 9.6 volts will shorten its life expectancy and may even permanently damage the battery causing it to fail to charge, fail to hold a charge, or even swell - never use a damaged or swollen battery. Keep it away from anything flammable and recycle it as soon as possible.

CAUTION: The battery should always be allowed to come to room-temperature before charging. Charging a hot or cold battery might delay charging or damage the battery. For best results, charge the battery at temperatures between 50º and 80ºF (10º-30ºC).
