What’s in the box

• Package Content: A pair 7.4V 3000mAh Rechargeable Lithium Polymer Batteries (Please charge batteries for 3–4 hours before your first use).
• Two rechargeable LiPo batteries are included to keep you powered during longer sessions.

Design, performance and compatibility

These batteries are rated at 7.4V and 3000mAh, offering dependable energy delivery for extended wear in cold environments. The 2-pack format supports uninterrupted use—ideal for back-to-back activities or easy swaps between sessions. They are designed to fit Sun Will battery ski gloves and electric heated motorcycle gloves, providing reliable power where it matters. They are not intended for heated socks or glove liners, due to pocket sizing differences.

Important sizing and charging notes

• ATTENTION: 3000mAh is larger than 2200mAh, so this size cannot be used in battery socks or glove liners whose pockets are too small.
• 2pcs Rechargeable Lithium polymer Batteries Included. Charge with Sun Will chargers only, and remove the battery from heated gloves or socks during charging.
• Batteries have an estimated life of 500–600 charging cycles. If stored for long periods, charge every six months to maintain readiness.

Care, storage and practical use

Store batteries in a cool, dry place away from direct heat or moisture. In everyday use, you may experience consistent warmth during commutes, outdoor activities, or winter hobbies, with the two-battery setup reducing downtime between charges. A simple charging workflow helps you stay prepared for your next outing without frequent replacements.

Real-world scenarios

From early-morning runs to slope-side breaks, Sun Will batteries are designed to simplify warmth on frosty days. Paired with Sun Will heated gloves or compatible gear, they offer a cohesive power solution for outdoor exploration. While warmth isn’t guaranteed, the dual-pack design allows flexible rotation between charges for longer adventures.

Safety and best practices

Always follow the charging guidelines. Remove batteries during charging and use only the recommended Sun Will chargers to help preserve battery health and performance over time.
