Background battery AGM Ultracell

AGM Ultracell 12V 18Ah battery: Autonomy and durability for your projects

This new type of sealed battery uses "absorbed glass mat batteries" technology. This technology uses a thin sheet of boron-silicate fiber between the lead plates in the battery .This thin sheet is soaked with electrolyte (70% water and 30% acid).

Advantages

AGM batteries have many advantages compared to conventional lead-acid batteries and gel batteries :

They are maintenance free, weatherproof.

No gas release, shock resistant.

Low self-discharge : 1 to 3% per month (unlike a normal lead acid battery which is discharged very quickly if not used sometimes).

Life is increased therefore the purchase price is profitable over time, not to mention the performance gain.

As the electrolyte is soaked into the fiber it can not sink even in case of breakage of the battery box, thus even the transport is much easier and safe. With no liquid, GM foods are not very sensitive to the damaging effects of frost.

For solar applications, the AGM are ideal : no maintenace, no gas release, conventional loading rates which then allows to use any standard charging system, minimum maintenance during the winter.
