Description
12V 12Ah Lithium Battery — CLI12-12
The Canbat CLI12-12 is a 12V 12Ah lithium battery delivering 153.6Wh of usable LiFePO4 energy in a compact 151 × 99 × 95 mm footprint at just 3.3 lbs (1.50 kg) — a premium lithium replacement for 12V 12Ah sealed lead-acid batteries used in alarm systems, UPS units, emergency lighting, access control equipment, communications infrastructure, and compact auxiliary power systems. Equipped with standard F2 (T2) blade terminals for direct compatibility with existing SLA battery connectors and enclosures, the CLI12-12 installs into existing equipment without wiring modifications, adapters, or hardware changes.
The primary advantage of the CLI12-12 over the sealed lead-acid batteries it replaces is not runtime — it is lifecycle, standby reliability, and reduced service frequency. Where a 12V 12Ah SLA battery typically delivers 300–500 cycles before capacity degrades to the point of replacement, the CLI12-12 delivers 3,000–5,000 cycles at 100% usable depth of discharge — extending the service interval by a factor of ten or more and significantly reducing total cost of ownership in deployments where battery replacement requires a scheduled service visit.
It ships free across Canada and the USA, carries a 10-year warranty, and is built with UL 1642 certified cells. For Canada and USA orders, there are no import duties or cross-border complications.
F2 Terminal Compatibility — Direct SLA Replacement
The CLI12-12 uses standard F2 (T2) blade terminals — the same terminal format found on the vast majority of 12V 12Ah sealed lead-acid batteries used in alarm panels, UPS cabinets, emergency lighting fixtures, and access control systems. This means the CLI12-12 connects directly to existing battery harnesses and spade connectors without modifications — a genuine drop-in replacement at the connector level, not just the voltage level.
A sealed lead-acid battery at 12Ah nominal delivers approximately 6Ah of usable energy before reaching the depth-of-discharge limit that protects its cycle life. The CLI12-12 delivers its full 12Ah at 100% usable depth of discharge — twice the accessible energy in the same physical format and enclosure dimensions, with stable voltage maintained throughout the entire discharge cycle. For standby applications, lithium chemistry also maintains capacity more reliably during extended float periods compared to SLA batteries, which degrade silently and may fail to deliver rated backup time when actually needed.
At 3.3 lbs (1.50 kg) — approximately half the weight of a 12V 12Ah SLA battery — the CLI12-12 reduces enclosure load, simplifies installation in wall-mounted panels and ceiling-mounted emergency units, and improves handling in compact equipment housings where battery access is constrained.
Applications
Alarm Systems & Security Infrastructure
The CLI12-12 is a direct lithium replacement for the 12V 12Ah SLA batteries used in commercial and residential alarm panels, motion detection systems, security control units, and video surveillance backup power. F2 terminal compatibility ensures connector-level replacement with no rewiring. The 3,000–5,000 cycle life significantly reduces replacement frequency compared to the 300–500 cycles typical of SLA batteries in alarm system standby service — fewer service visits, lower maintenance cost, and more consistent standby performance over the installed life of the equipment.
UPS Systems & Standby Backup Power
For small and mid-size UPS units protecting network equipment, communications infrastructure, point-of-sale systems, and critical electronics, the CLI12-12 provides a lithium upgrade that delivers twice the usable backup energy of the SLA battery it replaces — in the same enclosure, with longer service life and without the sulfation degradation that reduces SLA battery capacity during extended standby periods between discharge events.
Emergency Lighting & Exit Sign Backup
Emergency lighting units, exit signs, and egress lighting systems that use 12V 12Ah SLA batteries for backup power are direct CLI12-12 replacement candidates. Lithium chemistry maintains capacity more reliably during extended standby compared to SLA batteries, which degrade silently and may fail to meet minimum illumination duration requirements during an actual emergency event if replacement intervals are not strictly observed.
Access Control, Remote Monitoring & Field Equipment
For access control panels, gate operators, intercom systems, trail cameras, remote monitoring stations, and compact field instrumentation where a 12V 12Ah SLA battery is the standard power source, the CLI12-12 delivers a lithium upgrade with no compatibility changes — same voltage, same F2 terminal format, significantly longer service life, and lower long-term replacement cost in deployments where service access is scheduled or logistically constrained.

Installées dans le bloc-piles de notre scooter de mobilité Scout 4, ces batteries ont une durée de vie bien plus longue que les batteries au plomb-acide d’origine. Le poids du bloc-piles a été réduit de 50 % et le taux de décharge lorsqu’elles ne sont pas utilisées est nettement inférieur. Je les recommande à tout le monde.
