Yuasa 12V 7Ah SLA (NP7-12FR)

• Model: Yuasa NP7-12FR
• Type: Valve-Regulated Lead-Acid (VRLA), sealed (maintenance-free)
• Nominal Voltage: 12V
• Capacity: 7Ah (at 20-hour rate)
• Design life: Typically 3–5 years in standby use
• Flame Retardant: Yes (“FR” indicates flame-resistant case material)

Key Features

• Maintenance-free design
  Fully sealed construction means no electrolyte topping-up is required.

• Spill-proof and leak-resistant
  Uses absorbed glass mat (AGM) technology to immobilise the electrolyte.

• Flame-retardant ABS case
  The casing meets UL94 V-0 flame-retardant standards, improving safety in fire-sensitive environments.

• Rechargeable and versatile
  Suitable for both float (standby) and cyclic applications.

• Low self-discharge rate
  Retains charge well during storage, making it dependable for backup systems.

• Wide operating temperature range
  Typically operates effectively from around -20°C to +60°C (performance varies with conditions).
