Ongo Vision Long-Term Storage Guide

Overview

This guide provides important information about storing Ongo battery for extended periods without recharging.

The battery gradually loses charge over time, even when not in use.

Typical self-discharge rate: 2-3% per month under proper storage conditions.

Extended storage without recharging can reduce the battery's overall capacity.

This may result in shorter runtime when the battery is eventually used.

If left uncharged for too long, the battery voltage may drop to a critical level.

Deep discharge can cause permanent damage, potentially rendering the battery unusable.

A passivation layer may form on the battery's electrodes over time.

This can reduce the battery's efficiency and capacity.

This battery includes a built-in protection circuit board (PCB) that provides:

- Overcharge protection: Cuts off at 4.325V ± 0.05V

- Deep discharge protection: Cuts off at 2.5V ± 0.1V

- Overload protection

Note: While these features offer some protection, they don't eliminate all risks associated with long-term storage.

1. Charge Level: Store the battery at a partial charge (40-50%) if you know it won't be used for a while.

2. Storage Environment: Keep the battery in a cool, dry place with a temperature around 25°C (77°F).

3. Regular Checks: Periodically check and recharge the battery if storing for extended periods.

4. Avoid Full Discharge: Never leave the battery in a fully discharged state for long periods.

By following these guidelines, you can help maintain the health and performance of Ongo battery, ensuring it's ready for use when needed.
