AGM batteries, or Absorbent Glass Mat batteries, are a type of lead-acid battery that offer several advantages over traditional flooded lead-acid batteries. AGM batteries are sealed, maintenance-free, and have a longer lifespan than flooded batteries.
This sealed lead-acid battery employs lead plates suspended in an electrolyte. For example, if you are running a 5-amp load, the 100Ah capacity will last roughly 20
The amount of battery acid you should add to distilled water depends on the size of your battery. Typically, you should add enough acid to bring the specific gravity of the battery to the correct level. This is usually between 1.215 and 1.260 for most lead-acid batteries. Can you use distilled water instead of battery acid in a lead-acid battery?
The normally recommended maximum charge rate is C/4 to C/5, ie. 1/4 to 1/5 of the battery capacity in Ah. If your battery capacity is 90Ah then 30A is C/3. The battery should handle this OK but the voltage will rise faster. Above ~13.8-14.4V (2.3-2.4V per cell) the battery will ''gas'' as the water breaks down into hydrogen and oxygen.
