– The photo in the battery testing material shows an imbalance in the Tyumen battery: more positive plates than negative ones in each section. The question arises: why this approach is taken?
– At the Tyumen battery plant, experts explained that during operation the positive plates tend to wear more quickly. To counteract this, the plates are made thicker, 0.9 mm for positives versus 0.7 mm for negatives. This extra thickness helps sustain performance over time.
– A deliberate count adjustment was also implemented in the specified battery design: eight positive plates and seven negative plates per section. The goal is to boost overall capacity while maintaining structural integrity and charge dynamics.
– In a standard configuration, a healthy battery shows eight positive plates and seven negative plates, whereas a simplified or “hacky” version might feature six positives and five negatives. The ratio and total plate count influence how much current the battery can supply in starter discharge mode, as well as the available energy reserve. A smaller plate count tends to raise current density on the plate surfaces, which can significantly shorten plate lifespan.
– The larger the total surface area of the plates, the higher the potential current during starter discharge, and the greater the energy reserve. Batteries with fewer plates often experience increased current density on the active surfaces, which can dramatically shorten plate life and reduce longevity in real-world use.
– For questions, inquiries should be directed through the official publications and notes associated with the Tyumen battery program. [Source: Tyumen battery plant technical notes].
