ASOL 18650-2600mAh Rechargeable Lithium Battery — The Trusted Power Choice for Electric Toothbrushes & Personal Care Devices
Power your electric toothbrush with the ASOL 18650-2600mAh lithium battery — a premium rechargeable battery cell trusted by leading oral care brands worldwide. Engineered for consistent performance, extended runtime, and built-in safety, this is the battery your products — and your customers — can count on.
🔋 High Capacity: 2600mAh Means Less Charging, More Brushing
The ASOL 18650-2600mAh delivers 2600mAh of power in a compact 18650 form factor. Your customers get 2–4 weeks of daily electric toothbrush use on a single charge — cutting down on charging frequency and keeping their oral care routine seamless. No interruptions. No frustration. Just a consistently fresh clean every morning.
⚡ Stable 2.6A Discharge: Consistent Power from Start to Finish
Inconsistent battery voltage causes motor speed to drop mid-brush — a complaint that leads to returns and negative reviews. The ASOL 18650 maintains a stable 2.6A discharge current throughout the entire charge cycle, ensuring your toothbrush motor runs at full power from the very first second to the very last. Consistent performance. Every time.
🛡️ Built-in 5-Layer Safety Protection
Safety is never optional in personal care devices. This ASOL lithium battery comes with comprehensive built-in protection against every common battery failure mode:
- ✅ Over-charge protection
- ✅ Over-discharge protection
- ✅ Over-current protection
- ✅ Short-circuit protection
- ✅ Over-temperature protection
Protect your product. Protect your brand. Protect your customers.
📐 Compact 66×18.6×18.6mm | Lightweight 46g — Fits Any Slim Toothbrush Design
At just 66mm long and 18.6mm in diameter, the ASOL 18650 slides into ultra-slim electric toothbrush handles without adding bulk. Weighing only 46 grams, your toothbrush stays light and easy to hold — especially important for travel-sized and kid-friendly designs. Premium performance. Premium feel.
🔄 300+ Charge Cycles — Built to Last
The ASOL 18650 is rated for 300+ full charge cycles at 80% depth of discharge. That’s over a year of daily brushing with zero significant capacity loss. Fewer battery replacements mean fewer warranty claims, lower support costs, and happier customers who come back for more.
