EMS FC-006-005 6V 5.0Ah AGM VRLA Rechargeable Battery | 6-9 Years Design Life, UL94HB Container
£23.19 (inc VAT: £27.83)
Key features
- 50A surge current for 5 seconds
- ~24mΩ internal resistance when fully charged
- Self-discharge under 3% monthly at 25°C
Summary
The EMS FC-006-005 is a 6V 5.0Ah sealed lead acid battery built for standby power in fire, security and emergency lighting systems, and it stands out on its low internal resistance of around 24mΩ when fully charged, which keeps voltage drop down even when a connected device pulls a sharp current spike.

For you on site, that means less risk of nuisance low-voltage trips on circuits with sounders, strobes or lock release mechanisms, where the current draw isn’t constant. A battery that copes with these surges without sagging in voltage is one less thing to troubleshoot on a callback.
SSB rates the SB 5-6 for a 50A discharge over 5 seconds and a 250A short circuit current, giving it headroom for brief high-load events well beyond its steady 5.0Ah capacity. Combined with a self-discharge rate of under 3% per month at 25°C, it’s a sensible fit wherever you need a compact valve regulated lead acid (VRLA) battery that holds its charge between maintenance visits.
Features
- Low internal resistance – around 24mΩ fully charged supports higher current draw without excessive voltage sag
- High surge current rating – handles 50A for 5 seconds, useful for sounder circuits or lock release loads
- Low self-discharge – under 3% monthly at 25°C reduces top-up charging between site visits
- Wide discharge temperature range – rated -20°C to +60°C for unheated plant rooms or external cabinets
- Fast-on 4.8mm terminals – quick, secure push-on connections on site
- Sealed AGM/VRLA construction – maintenance-free, no electrolyte top-up required
- Flame retardant ABS case – manufactured to UL94HB, with UL94-V0 available as an option
- Compliant construction – manufactured to PN-EN 60896, PN-EN 61056 and PN-E-83016 standards under ISO 9001 and ISO 14001

FAQ
Yes. SSB specifies two charging voltage ranges for this battery: 6.85 to 6.94 VDC for standby use and 7.30 to 7.40 VDC for cycle use. Make sure your charger is set for the correct application, as using the standby voltage on a cyclic duty will undercharge the battery over time. The FC-006-005 uses fast-on 4.8mm terminals, which take standard push-on spade connectors common across fire and security equipment. No soldering or crimping is needed on the battery end. Yes, the maximum charging current is 1.50A. If your charger or power supply unit (PSU) isn’t current-limited to this figure, check the manufacturer’s charging guidance before connecting, as overcharging can shorten service life. EMS rates the FC-006-005 for a 6-9 year design life in standby use under the Eurobat general purpose classification. The datasheet’s life expectancy curve shows this drops off noticeably above around 25°C, so keeping the battery in a cool, ventilated enclosure will help it reach the upper end of that range. The charge temperature range is 0°C to +50°C, which is narrower than the -20°C to +60°C discharge range. If the battery is fitted in an unheated outdoor cabinet, check that charging won’t happen below freezing, or consider cabinet heating. Yes, it’s a sealed AGM VRLA design with no electrolyte top-up required. SSB’s storage guidance does recommend a supplementary charge before use if the battery has been in storage, so it’s worth checking stock age before fitting.Can I use the FC-006-005 for cyclic applications as well as standby?
