Customer ServiceIn fact, factory defects are responsible for less than 7% of battery failures. So why do batteries fail? In most cases, it comes down to driving habits, environmental conditions and natural wear and tear. In this blog post, we will look at what causes battery failure and how to get the most life out of your battery.
Customer ServiceTo reduce dry-out, sealed lead-acid batteries use lead-calcium instead of the lead-antimony. The optimum operating temperature for the lead-acid battery is 25*C (77*F). Elevated temperature reduces longevity. As a guideline, every 8°C (15°F) rise in temperature cuts the battery life in half. A VRLA, which would last for 10 years at 25°C (77°F), would only be
Customer ServiceLead-acid batteries, widely used across industries for energy storage, face several common issues that can undermine their efficiency and shorten their lifespan. Among the most critical problems are corrosion, shedding of active materials, and internal shorts.
Customer ServiceBattery failures caused by sulphation, wear and tear, deep cycling and physical damage are not manufacturing defects and are not covered by the Yuasa guarantee. Under normal operating conditions, a battery cannot become discharged on its own. The reason can normally be traced back to: Malfunctioning alternator, regulator, or starter motor
Customer ServiceValve-regulated batteries often fail as a result of negative active mass sulfation, or water loss. For each battery design, and type of use, there is usually a characteristic, dominant aging mechanism, determining the achievable service life.

Customer ServiceThis is the reason why lead-acid batteries must be charged as soon as possible (to prevent the building up of lead sulfate). Charging of the lead batteries is usually done by providing an external current source. A plug is inserted which
Customer ServiceSealed lead-acid batteries, also known as valve-regulated lead-acid (VRLA) batteries, are maintenance-free and do not require regular topping up of electrolyte levels. They are sealed with a valve that allows the release of gases during charging and discharging. Sealed lead-acid batteries come in two types: Absorbed Glass Mat (AGM) and Gel batteries.
Customer ServiceJust because a lead acid battery can no longer power a specific device, does not mean that there is no energy left in the battery. A car battery that won’t start the engine, still has the potential to provide plenty of fireworks should you short the terminals.
Nevertheless, positive grid corrosion is probably still the most frequent, general cause of lead–acid battery failure, especially in prominent applications, such as for instance in automotive (SLI) batteries and in stand-by batteries. Pictures, as shown in Fig. 1 taken during post-mortem inspection, are familiar to every battery technician.
In both flooded lead acid and absorbent glass mat batteries the buckling can cause the active paste that is applied to the plates to shed off, reducing the ability of the plates to discharge and recharge. Acid stratification occurs in flooded lead acid batteries which are never fully recharged.
Internal shorts represent a more serious issue for lead-acid batteries, often leading to rapid self-discharge and severe performance loss. They occur when there is an unintended electrical connection within the battery, typically between the positive and negative plates.
At the same time the more watery electrolyte at the top half accelerates plate corrosion with similar consequences. When a lead acid battery discharges, the sulfates in the electrolyte attach themselves to the plates. During recharge, the sulfates move back into the acid, but not completely.
Contamination in sealed and VRLA batteries usually originates from the factory when the battery is being produced. In flooded lead-acid batteries, contamination can result from accumulated dirt on top of the battery and when the battery is being watered. Watering the battery with tap water has a serious consequence on the battery.
