The 24-85-21 battery is a mid-sized deep-cycle lead-acid battery primarily designed for sustained low-rate discharge applications. With dimensions typically around 21 cm in length and 17-18 cm in height, this 85Ah capacity unit operates at 24V nominal voltage, making it suitable for mobility aids, marine electronics, and small-scale solar storage. Its AGM (Absorbent Glass Mat) construction ensures leak-proof operation and vibration resistance.
Understanding Forklift Battery State of Charge: A Complete Guide
What devices commonly use 24-85-21 batteries?
These batteries power electric wheelchairs, floor scrubbers, and light-duty UPS systems. Their compact size allows integration where space constraints exist while maintaining high energy reserves. Pro Tip: Avoid discharging below 50% capacity to prevent premature sulfation in lead-acid variants.

How does voltage affect 24-85-21 applications?
The 24V configuration reduces current draw by 50% compared to equivalent 12V systems, minimizing heat buildup in wiring. This makes them ideal for golf cart auxiliary systems and RV power networks requiring extended runtime between charges.
What charging specifications apply?
Optimal charging uses three-stage smart chargers delivering 28.8V absorption and 27.2V float voltages. Bulk charging typically requires 15-20% of capacity (12.75A for 85Ah). Pro Tip: Temperature-compensated charging (±3mV/°C/cell) prevents overvoltage damage in varying environments.

FAQs
Yes, but ensure charging voltages match AGM requirements—flooded battery chargers risk undercharging by 10-15%.
What’s the typical weight range?
22-28kg depending on plate thickness; AGM versions weigh 3-5kg less than flooded equivalents due to denser active material.
