Generally speaking there are two different types of lead acid battery, Starting and Deep Cycle. If a starting battery is routinely deep cycled (discharged below 20%-50% of max capacity) it will generally fail after 30-150 cycles. The same starting battery will last for thousands of cycles if it is just used normally (2% - 5% discharge).
These phosphates precipitate the solids to the bottom of the boiler drum. At the bottom of the boiler drum there is a bottom blow to remove these solids. These chemicals also include anti-scaling agents, oxygen scavengers, and anti-foaming agents.
Chemical disinfection can be used when instruments will be damaged by heat. Some chemicals that may be considered include glutaraldehyde 2% for 20 minutes, hydrogen peroxide 6%â7.5% for 20â30 minutes, peracetic acid 0.2â0.35% for 5 minutes and ortho-phthalaldehyde (OPA) for 5â12 minutes.
