What protections and quality checks come with this replacement cell?

The DDONG AEC353535 is manufactured and inspected under quality control standards and undergoes testing before shipping.

How should I charge and care for the new battery to maximize lifespan?

New lithium batteries perform best after a few conditioning cycles.

Regular moderate charging and avoiding prolonged full discharges will help keep the battery healthy over time.

• Perform 3–5 full charge/discharge cycles initially for top performance.
• Avoid extreme temperatures while charging and storing the headphones.
• Do not leave the headphones plugged in continuously for long periods.
• If unused, store partially charged (around 40–60%) for best shelf life.

Will this battery work with every Beats Solo3 or Solo2 model?

The AEC353535 battery is made to be compatible with the majority of Beats Solo3 and Solo2 wireless headphone units, but internal revisions across production years can vary. Check the battery size and connector type in your earcup before starting the swap. If unsure, compare the original battery’s label or reach out to the seller with photos for confirmation.

• Compatible with many Solo3 and Solo2 units, but verify physical fit first.
• Inspect your original battery dimensions and connector before purchase.
• Contact DDONG customer service with pictures for compatibility help.
• Some models may require additional disassembly steps or soldering skills.
