Sealed Lead Acid batteries can be affected by ambient temperatures, charging patterns, and usage behaviors. The specification sheets linked below contain graphs and further information on the characteristics of the batteries used in VCUs.
- Scout VCU: 12V, 14Ah SLA battery (Specification Sheet)
- Power Pack: 12V, 9Ah SLA battery (Specification Sheet)
If purchasing new batteries, Miovision recommends the PowerSonic brands linked above. If PowerSonic is not available, another battery with the same specifications can be purchased. Miovision cannot guarantee that non-PowerSonic batteries will match the estimated Recording/Standby times below
- Scout VCU: 72 hours (3 days)
- Scout VCU + Power Pack: 164 hours (7 days)
Estimated recording times are based on deployments in optimal ambient temperatures, using batteries charged and maintained following Miovision’s best practices
- Scout VCU: 60 days
The VCU operates in Standby mode when it is not recording, which will impact overall recording times and battery power levels over time. The Power Pack does not operate in a standby state, however there will still be some voltage loss over time when in storage. When storing the VCU or Power Pack for an extended period of time, it is recommended to charge it at least every 30 days to ensure the batteries retain a charge reference. As a rough guideline to calculate deployment capabilities, a Scout Control Unit loses 1 hour of recording every 100 hours in standby.
The impact of temperature
Battery capacity as a percentage for a given temperature is as follows:
- 104°F (40°C) to 102% rated capacity
- 77°F (25°C) to 100% rated capacity
- 32°F (0°C) to 85% rated capacity
- 5°F (-15°C) to 65% rated capacity
