When the accumulator battery is supplying a load, what percentage of the full capacity does it need to be charged after it is discharged?

When an accumulator battery is supplying a load, it is crucial to maintain its health and longevity by ensuring it is recharged to a suitable level after discharge. The correct percentage of 20-30% after discharge helps to prevent deep discharge, which can significantly reduce the battery's lifespan and effectiveness.

If a battery is regularly discharged beyond this threshold, it may suffer from sulfation, where lead sulfate crystals build up and hinder the battery’s performance. Additionally, charging the battery to only 20-30% capacity allows for the battery to recover adequately without causing excessive strain on its cells. This recharging range strikes a balance between maintaining battery health and ensuring it's ready for subsequent operations.

In contrast, lower recharge percentages may not provide sufficient power for the next use, while higher percentages could indicate overcharging risks, leading to overheating or reduced efficiency. Thus, the 20-30% range is recommended for optimal performance and longevity of the accumulator battery when used for forklift applications.
