✅ Why Our Warranty Stands Out

Unlike marketplace sellers with short buyer protection windows, we handle claims directly — no automated disputes, no endless back-and-forth.

🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Keep your motherboard RTC and critical devices running with this ML2032 rechargeable lithium coin cell battery. Designed as a direct replacement for the standard CR2032 but with one key advantage — it‘s rechargeable. Ideal for devices that trickle charge the battery while powered on (PC motherboards, PLC controllers, industrial computers), this ML2032 can be recharged hundreds of times, offering an economical and environmentally friendly alternative to disposable cells.
Manufactured with high-quality lithium manganese dioxide chemistry and multi-layer safety protection against overcharge, over-discharge, and short circuits. UL recognized (MH12568), CE, and RoHS certified for safe transport and use. Perfect for long-term backup power applications — CMOS memory backup, real-time clocks (RTC), and low-current sensors. For reference, third‑party retailers sell this battery for approximately $8 to $15 per piece.
Compatibility Note: Same dimensions as CR2032 (20mm diameter x 3.2mm height) — fits standard CR2032 battery holders. For Logitech K750 Solar Keyboard, the original ML2032 is soldered directly to the board — professional soldering recommended. For Sega Dreamcast, a coin battery holder and diode are required — do not install directly without proper modification. Always verify your device’s power circuit supports rechargeable batteries before replacing a non-rechargeable CR2032.
Battery Care Tips: Avoid full discharge — recharge when voltage drops below 2.5V. Use a dedicated coin cell charger (2.9mA constant current recommended). Do not expose to high temperatures or direct sunlight. For long-term storage, keep at 40%-60% charge in a cool, dry place. If you notice swelling or leakage, stop use immediately.

Frequently Asked Questions

The ML2032 rechargeable battery for motherboard CMOS backup is compatible with devices that use a 3V coin cell for RTC or memory backup and provide trickle charging capability. Common applications include PC motherboards (CMOS settings and system clock), PLC controllers, industrial computers, POS systems, medical instruments, Logitech K750 Solar Keyboard (original battery is ML2032 — soldered to board), Sega Dreamcast (requires battery holder and diode mod), alarm systems, calculators, remote controls, and IoT sensors. Important: The ML2032 has the exact same dimensions as CR2032 (20mm diameter × 3.2mm height) and fits standard CR2032 holders. However, not all devices are designed to charge rechargeable batteries — verify your device’s power circuit before replacing a non-rechargeable CR2032. If your device does not provide charging current, stick with a primary CR2032.

The ML2032 65mAh 3V battery has a nominal capacity of 65mAh, with actual capacity typically reaching 65-70mAh when fully charged. Rated voltage is 3V, with a maximum charge voltage of 3.3V and discharge cut-off voltage of 2.0V. Standard charge current is 2.9mA (0.045C), and standard continuous discharge current is 0.2mA (max continuous 0.5mA recommended). Operating temperature range: -20°C to 70°C. Cycle life: up to 1000 cycles at 10% depth of discharge (6.5mAh discharge) or 300 cycles at 20% depth of discharge (13mAh discharge). UL recognized (MH12568), CE and RoHS certified. Dimensions: 20mm diameter × 3.2mm height — identical to CR2032. Weight: 3.1g. Use only a dedicated coin cell charger (constant current 2.9mA recommended) — never use a standard Li‑ion charger.

Installation depends on your device type. For standard CR2032 battery holders: simply remove the old CR2032 and insert the ML2032 with the positive (+) side facing up. Ensure the holder‘s metal contacts are clean. For devices with soldered coin cells (e.g., Logitech K750 keyboard, industrial motherboards): professional soldering is required. Desolder the old battery, clean the pads, and solder the new ML2032 in place — observe polarity (positive side marked with “+” on the battery). For Sega Dreamcast mod: requires installing a coin battery holder and a diode (in series with the positive terminal) to prevent the Dreamcast’s power supply from overcharging the battery. If you choose DIY battery replacement, use a temperature-controlled soldering iron (≤300°C), avoid prolonged heating, and never solder directly to the battery body — use pre-soldered tabbed ML2032 if available. If you are not comfortable with soldering, professional installation is recommended.
