Alarm / Gate / UPS Lithium Battery Upgrade (12v 7Ah SLA Alternative)

12v6ah-MainFront_1024x1024@2x.png

12v 7Ah sealed lead-acid (SLA) batteries are typically installed in small electronics that require backup power, like alarm systems 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).

This battery can directly replace a sealed lead acid 12v 7Ah battery (same size, same charging voltages) and is an upgrade in terms of how many cycles the battery can do (how many time can be used before needs replacing).

Please note that while this is technically a 12v 6Ah battery, it performs like a 12v 7Ah lead acid battery in most applications since it is able to consistently deliver its full available capacity, whereas the lead acid 12v 7Ah battery will degrade rapidly in capacity as it ages, or when under high load.

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 75W with that number. Example, a 12v alarm system drawing 1A load, has a 12W (12v x 1A = 12W) load, so it can run from this battery for 6hrs 15min (75 / 12 = 6.25).
