Often in our field, we hear questions like, "Why did my battery stop working?", "Why is my battery losing power?", or even "Why did my battery fail so quickly?" The Battery Professionals are here to explain some basic reasons why your battery might stop functioning properly or even get completely damaged.

Overcharging The most common cause of battery failure is overcharging. Overcharging occurs when the battery remains connected to a power source for an excessive amount of time, resulting in its destruction. Continuous charging causes increased temperature and the breakdown of the battery's chemical components. Overcharging can also happen when the battery receives more current than it can handle. Tips: Opt for maintenance chargers that match your battery and can stay connected for 364 days a year without causing overcharging (e.g., Telwin Touring 11).

Complete Discharge Apart from overcharging, a battery can also be damaged by complete discharge. Fully discharging a battery can harm its components, preventing it from charging properly again. This can happen, for example, if your vehicle is left unused for an extended period (over two weeks). Tips: If you need to leave your vehicle unused for a long time, disconnect the battery's positive terminal or connect it to a maintenance charger to preserve its charge.

Charging Errors Using incompatible chargers or low-quality chargers can lead to unstable energy delivery, causing long-term damage to the battery. Tips: Purchase chargers from authorized retailers and keep the warranty by following the terms.

Extreme Temperatures Extreme temperatures (very high or very low) also play a significant role in affecting the battery's performance. High temperatures cause uncontrolled chemical reactions, while low temperatures significantly reduce the battery's capacity. Tips: To keep your battery healthy during hot months, use windshield covers and regularly check the battery with a tester (e.g., Topdon BT100). During cold months, you can connect your battery to a maintenance charger when the vehicle is unused for a long time. This keeps it in good condition and fully charged, avoiding deep discharge due to cold (e.g., Victron BlueSmart 12/5A).

Battery Age Like all electronic components, batteries have a specific lifespan. Over time, their performance decreases due to natural wear and tear. Tips: A well-maintained battery lasts 3–4 years.

Short Circuit Finally, a short circuit can occur due to poor installation or damage to the battery terminals, causing rapid discharge and destruction. Tips: If you have doubts about your battery installation, call us at 2105981637 for assistance.

When it comes to choosing a battery for our vehicle or equipment, we often face the question of which technology to prefer. The main battery technologies we encounter are conventional lead-acid, AGM, EFB, and GEL. But what are the differences in their technology? Conventional lead-acid batteries are available in open and closed types. They are the oldest type and are designed to be used in a wide range of products. Closed-type accumulators contain lead sulfate plates and sulfuric acid electrolyte, which is added by us before starting its full charge.

Open-type batteries contain an electrolyte solution but do not have lead plates, requiring regular maintenance and refilling with deionized water. AGM batteries, on the other hand, differ significantly from simple conventional ones. They feature special glass fiber separators between the lead plates that absorb the electrolyte, preventing leaks. They are suitable for boats, motorcycles, and cars with start-stop systems, where high vibrations and sudden movements occur.

EFB batteries are widely used in start-stop vehicles that do not have an energy recovery system in braking. These batteries have denser plates and an improved composition. The positive plates are wrapped in special microfiber material that absorbs and retains liquid electrolyte, preventing excessive shedding of active material and significantly slowing down the sulfation process. Lastly, GEL batteries differ greatly from all other batteries, even in the materials of their plates. GEL batteries contain calcium plates and a silica gel where the electrolyte is housed. Due to this difference, we must be very careful about how we charge GEL batteries, as they require low voltages and a charger suitable for GEL batteries. This avoids the formation of voids in the silica gel and premature wear. They are ideal for start-stop vehicles, boats, and any machinery that can accommodate GEL batteries.
