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 up to 10A in 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, or a UPS that is no longer lasting through loadshedding, 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.
Using 12v 7Ah SLA batteries inside small UPS units (as is the standard) is especially troublesome if there is regular loadshedding, since they are not meant for regularly handling high current, being discharged often and discharged too low. When they are frequently drained (like during load shedding), or placed under high load like a UPS places on them, then they are internally damaged, and you will find that you need to replace them 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 128W 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 5hrs 20min (128 / 24 = 5.330).
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.
