Lead-acid batteries, such as those used to power electric forklift trucks in intralogistics, are meant to be used on a regular basis. If they remain unused for any length of time, the inevitable result is a loss of capacity.
When do we start talking about a deep discharge?
A deep discharge occurs when the residual capacity falls below 20 percent. This can damage the battery or render it unusable. Unfortunately, many operators are completely unaware that this has happened until they try to restart their production lines or logistics systems. Regeneration of batteries in a deep discharge state is often no longer possible with conventional chargers, and necessitates a new purchase involving high costs and wasted time.
How can I prevent batteries going into a deep discharge state?
Our battery chargers ensure that batteries do not go into a deep discharge state. Selectiva chargers are equipped with a conservation charge when they leave the factory, meaning that connected batteries are automatically charged very gently when not in use. Your batteries are therefore ready to use immediately, even if they have been out of action for a long time.
What should I do if a deep discharge nevertheless occurs?
In challenging times, however, a critical deep discharge state may still occur. What can an operator do in such situations? If a deep discharge occurs, our Fronius Selectiva battery chargers have a remedy up their sleeves, as they are equipped with a special deep discharge characteristic specifically for such emergencies. This is a clear advantage compared with other standard chargers, which often cannot be used when batteries are in a deep discharge state, as their voltages are too low and the batteries are consequently unable to detect them. The deep discharge characteristic enables the capacity and performance of the battery to be regenerated to such an extent that normal charging becomes possible again. This increases battery life and eliminates the cost of new purchases.
