12V 12Ah Alarm / Gate Lithium Battery (12V 7Ah High Capacity Upgrade)

Regular price R 1,499 R 999 Sale

Key Benefits:

- Increased storage capacity. This battery will open your gate twice as many times, or keep your alarm on for twice as long as an old 12v 7Ah battery.
- Increased life span (10 x longer than lead acid). Load shedding does not destroy these batteries and you can expect a 5+ year life span from them.
- Direct replacement for 12V 7Ah Lead Acid. This battery is exactly the same size and dimensions as standard gate and alarm batteries. Compatible with existing chargers and machines.

Ideal for use in:
- Gate motors backup battery
- Home and business Alarm system backup battery
- Access Control Gates backup battery
- Electric Fences backup battery
- CCTV backup battery

This is a very reliable lithium gate battery. This long life lithium upgrade is perfect if you are tired of replacing your 12v 7Ah sealed lead acid batteries regularly due to load shedding AND you want increased capacity so your battery can power equipment longer on a single charge.

This battery can directly replace a sealed lead acid 12v 7Ah battery (same size, same charging voltages), but it is also a capacity upgrade (stores 50% more energy), it can handle 12A continuous current, and is an upgrade in terms of how many cycles the battery can do (how many time can be used before needs replacing).

If you have an electronic gate that is very busy, a large alarm system, an electric fence, then this is the battery for you. It stores more energy, and will last through 10 times more loadsheddings than a sealed lead acid battery.

12v 7Ah sealed lead-acid (SLA) batteries are typically installed in small electronics that require backup power, like alarm systems, UPS devices, and gate motors, but they are not ideal for regularly handling high current, and being discharged often or discharged too low. Thus when they are frequently drained (like during load shedding), they are easily damaged, and you will find that you need to replace them quite often.
This lithium iron phosphate battery on the other hand has a high cycle rate (2000 cycles, versus 200 to 400 cycles of an SLA battery), it can handle higher current, and the internal battery management system protects the battery from overcharging or discharging too low.
That simply means this lithium battery replacement should last 10 times longer than the typical SLA battery it is replacing.

Other advantages are that there are no fumes, the self-discharge rate is less than 3.5% per month (SLA will drain itself dead in 12 months), the batteries weight 700g vs the 2kg average weight of a 12v 7Ah SLA battery, and they can be charged and discharged faster (at higher current).

TIP : To calculate how long this battery can last in your application, lookup the load power of the device it will be powering in Watts, then divide 150W with that number. Example, a large 12v alarm system drawing a 2A load, has a 24W load typically, so it can run from this battery for 6hrs 15min (150 / 24 = 6.25).

NOTE : If the extra capacity is not required, but you are simply tired of replacing your 12v 7Ah SLA battery often, then also see our Lithium Battery Upgrade (12v 7Ah SLA Alternative) product listing.

UPS NOTE : Only use this battery inside a UPS if the UPS low voltage disconnect can be set to 12v, or if you are sure the UPS will last longer than loadshedding. Otherwise if the UPS is run until it stops working (battery voltage too low and BMS low voltage protection triggered) then the UPS will not turn on when the power comes on. The battery BMS needs a charge to wake up and UPS won't turn on and charge it without battery being detected.

Questions & Answers

Ask a Question
  • Can these be put in series, and what is the charging voltage (min and max)

    Charging / Discharging :
    - Bulk Charging Voltage : 14.4 VDC
    - Float Charging Voltage : 13.8 VDC

  • Guarantee?

    Warranty 3 years / 3000 Cycles 

    Expected Lifespan = More than 5 years

  • Can this be used in a UPS, in series, for 24V?

    These batteries are not compatible with UPS. They are mainly for Alarm Systems and Gate Motor replacement batteries.

12amp 12v Lithium battery

Not my 1st ones i use. I am an installer and used them previously in my own equipment. Absolutely a great product. Works perfectly on both the D5 smart and JVA Energisers.

12V, 12A lithium battery

Exceptional service! Fantastic battery!

Rory W.
So far so good.

The order was delivered within 2 days of order. I connected the battery to my system yesterday and it appears to be working well so far. Great service as always from Extreme Lights. Their products always match or exceed expectations, which is why I had no hesitation in ordering this battery from them. I expect the performance will live up to expectations.
