AGM 7Ah Solar Battery: Maintenance-free, high performance
This new type of sealed battery uses "absorbed glass mat batteries" technology. This technology uses a thin sheet of boron-silicate fiber between the battery's lead plates. This thin sheet is soaked in electrolyte (70% water and 30% acid).
Advantages
AGM batteries have many advantages over conventional lead-acid and gel batteries:
- Maintenance-free, leak-proof.
- No off-gassing, shock-resistant.
- Low self-discharge rate of 1 to 3% per month (unlike a normal lead-acid battery, which discharges very quickly if not used for some time).
- Longer life means a return on investment over time, not to mention improved performance.
- As the electrolyte is soaked in the fiber, it cannot leak out, even if the battery casing breaks, so transport is much easier and safer. As they have no liquid, AGMs are highly insensitive to the damaging effects of frost.
- For solar applications, AGMs are ideal: no maintenance (which means they can be placed in inaccessible locations), no off-gassing (no danger of explosion or health hazards for users), use of conventional charging rates, which means they can be used with any standard charging system, and minimum maintenance during winter storage.
Life cycle versus depth of discharge
Comparative table of price per useful kWh over battery life at a glance!
There are many different storage technologies: Gel or AGM batteries, lithium batteries, OPzS and OPsV. It's not easy to choose the right technology for your needs. Each technology has its own characteristics (size, power, cost, number of cycles and service life, etc.). With this table, you can quickly compare the price per useful kWh over the lifetime of the batteries.
C10 = 10-hour charge/discharge test.
C24 = examination of a charge or discharge in 24 hours.
