You may notice that batteries are often rated for much higher CCA or 'Cold Cranking Amps' values, but since they deteriorate over time, that extra margin will come in handy. Especially in colder weather. Lead acid batteries as used in cars can last many years because they are used under near ideal conditions.
Ideally you can configure the cut-off coltage, such as with the depicted unit. So many lead acid batteries are 'murdered' because they are left connected (accidentally) to a power 'drain'. No matter the size, lead acid batteries are relatively slow to charge. It may take around 8 - 12 hours to fully charge a battery from fully depleted.
From that point on, it was impossible to imagine industry without the lead battery. Even more than 150 years later, the lead battery is still one of the most important and widely used battery technologies. Lead-acid batteries are known for their long service life.
Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.
Lead acid batteries comprise lead plates immersed in an electrolyte sulfuric acid solution. The battery consists of multiple cells containing positive and negative plates. Lead and lead dioxide compose these plates, reacting with the electrolyte to generate electrical energy. Advantages:
