6 Frequently Asked Questions about “Failure symptoms of lead-acid battery pack”
What causes internal shorts in lead-acid batteries?
Internal shorts in lead-acid batteries generally fall into two categories: hard shorts and soft shorts. Hard shorts are typically caused by paste lumps resulting from manufacturing defects. Soft shorts are the result of excessively deep discharges where the specific gravity becomes so low that lead begins to dissolve into the electrolyte.
Do lead-acid batteries self-discharge?
All lead-acid batteries will naturally self-discharge, which can result in a loss of capacity from sulfation. The rate of self-discharge is most influenced by the temperature of the battery's electrolyte and the chemistry of the plates.
What happens if a battery is left unchecked?
If left unchecked the battery will overheat and will start to evaporate the electrolyte. The overcharging will accelerate the break up of the active material and grids and the battery will lose performance. Examination of the battery will typically show low acid level and usually a black coating on filler plugs and a strong smell.
What happens if a battery is not recharged properly?
Additionally if the recharge does not recover the discharge cycle in full, the battery will exhibit loss of performance and concentration of the acid can occur between plates which can lead to corrosion and loss of performance.
What are the financial implications of a battery failure?
The financial implications of battery failures are significant. When a battery system fails, organisations face not only the direct replacement costs but also the indirect costs related to system downtime, potential damage to connected equipment and, in some cases, the loss of critical services.
Is a lead acid battery a live product?
Nevertheless, it should be clearly understood that wet (filled) lead acid battery is “a live” product. Whether it is in storage or in service, it has a finite life. All batteries once filled will slowly self discharge. The higher the storage temperature and humidity of the storage area, the greater the rate of self discharge.
