High-Capacity Replacement Lithium-Polymer Battery S85/WP10 — 8000mAh, 3.85V

Product Review (submitted on June 27, 2026):

Great value for the price. I needed a reliable backup battery for my UPS S80/UBS S85 device, and this Li-Polymer unit delivers consistent performance. It holds its charge well even when not in use for a few days. The build quality feels solid, and the 3.85V output matches the original specifications perfectly. If you’re looking to extend the life of your power bank or UPS system, this is a smart upgrade.
