Summary
The Casil CA650-V0 is a 6V 5.0Ah sealed lead-acid (SLA) battery moulded in a flame-retardant ABS casing, giving you a backup power cell you can fit inside enclosed fire alarm, emergency lighting or security panels with confidence in its fire behaviour under fault conditions.

For you as an installer, that self-extinguishing housing matters when panels are specified for restricted or occupied spaces, helping you meet site fire safety requirements without adding separate enclosure protection or re-specifying the battery mid-project.
Beyond the casing, the CA650-V0 delivers a genuine 50A surge for five seconds and a low 20mΩ internal resistance, so it copes with the brief high-current demands of alarm sounders, UPS switchover and emergency lighting test cycles without voltage sag.
Features
- Flame retardant ABS casing – suits installation inside enclosed panels and cabinets where fire behaviour of components is scrutinised
- 50A (5 second) surge discharge – copes with brief high-current demands from sounders, inverters or UPS switchover
- Low 20mΩ internal resistance – keeps terminal voltage stable under load, reducing nuisance low-voltage shutdowns
- Compact 70 x 47 x 100mm footprint – fits standard panel battery compartments without re-measuring the enclosure
- Dual charge voltage settings – 6.75-6.90V for standby float use or 7.2-7.4V for cyclic charging, so one battery suits both regimes
- 5 year design life at 25°C – supports longer service intervals before replacement is due
- Maintenance-free sealed construction – no topping up or acid handling on site visits
- UL, CE and ISO 9001/14001 certified – documented quality and safety compliance for your project file

FAQ
It uses an F1 blade terminal, as shown in the datasheet terminal diagram. Check your existing connector leads or adaptor tabs are rated for F1 before wiring it into a panel designed for a different terminal size. Yes. The datasheet gives separate charge voltage settings: 6.75-6.90V per cell for standby (float) use and 7.2-7.4V per cell for cyclic use, each with its own temperature coefficient. Set your charger to match the application rather than using one voltage for both. Casil states the CA650-V0 can be stored for up to 6 months at 25°C before it needs a freshening charge, with shorter intervals at higher storage temperatures. If a battery has been in your stockroom longer than that, give it a freshening charge before commissioning. No, it is a sealed, maintenance-free SLA design with no topping up required. Routine testing as part of your standard panel maintenance regime is still good practice to confirm it holds capacity. The datasheet rates it at 50A for 5 seconds maximum discharge current, with a low internal resistance of approximately 20mΩ supporting that surge. For continuous loads, refer to the constant current discharge table for the actual current your application draws. Its dimensions are 70mm length, 47mm width, 100mm container height and 106mm total height with terminals, which is a common footprint for this capacity class. Measure your existing compartment against these figures before ordering to confirm fit.What terminal type does the CA650-V0 use?
