Stealth Energy Stealth 200 Battery

Stealth Energy Stealth 200 Battery is a 12V, 20Ah power source built for demanding car audio builds, delivering high-current capability from a compact ABS enclosure. With a 300A (5s) max discharge and a T12 terminal, it is designed to support high-current demands in automotive audio systems.

• Nominal Voltage: 12V — Standard automotive voltage that aligns with most amplifiers and vehicle electronics.
• Nominal Capacity (20HR): 20.0AH — Indicates the energy available when pulled from the battery at a 20-hour rate (roughly 1A for 20 hours).
• Approx Weight: Approx 5.78 kg (12.74 lbs) — Reflects a dense, energy-packed package in a compact form factor.
• Terminal: T12 — The high-current terminal type used for solid connections to power distribution in performance installs.
• Container Material: ABS — Durable plastic enclosure designed to withstand typical under-boot and trunk environments.
• Max. Discharge Current: 300A (5s) — Enables short, high-current bursts typical of bass transients without immediate voltage collapse.
• Internal Resistance: Approx 15mB — Lower resistance helps minimize voltage drop under load and improves efficiency during peak demand.
• Nominal Operating Temp. Range: 25 +3 C (77+5 F) — Indicates the conditions under which the stated capacity and performance are specified.
• Dimension:
  • Length: 181.512 mm (7.14 inches)
  • Width: 7712 mm (3.03 inches)
  • Container Height: 167.512 mm (6.59 inches)
  • Total Height (with Terminal): 167.512 mm (6.59 inches)
• RATED CAPACITY:
  • 20.0 AH/1.00A: (20hr, 1.80V/cell, 25 C/77 F)
  • 18.6 AH/1.86A: (10hr, 1.80V/cell, 25 C/77 F)
  • 17.0 AH/3.40A: (5hr, 1.75V/cell, 25 C/77 F)
  • 15.3 AH/5.10A: (3hr, 1.75V/cell, 25 C/77 F)
  • 12.6 AH/12.6A: (1hr, 1.60V/cell, 25 C/77 F)
• Capacity affected by temperature:
  • 40 C (104 F): 103%
  • 25 C (77 F): 100%
  • 0 C (32 F): 86%
• OPERATING TEMP RANGE:
  • Discharge: -15~50 C (5~122 F)
  • Charge: 0~40 C (32~104 F)
  • Storage: -15~40 C (5~104 C)
• SELF DISCHARGE: Batteries may be stored for up to 6 months at 25 C(77 F) and then a freshening charge is required. For higher temperatures the time interval will be shorter.

The Stealth 200 is well-suited to configurations that require robust current delivery for multiple amplifiers or bass-heavy setups, offering a 20Ah baseline with clearly defined high-current capability and a compact, durable ABS enclosure that fits into common install spaces while maintaining predictable performance across a range of temperatures.
