7.4V 1500mAh Li-ion Replacement Battery for MAICO MPT-II Thermal Printer
The MAICO MPT-II replacement battery is a 7.4V 1500mAh lithium-ion power cell engineered for the Sanibel MPT-II / MAICO MPT-II thermal printer — the standard output device paired with MAICO hearing screeners, audiometers, and tympanometers in audiology clinics worldwide. When the original battery degrades, print quality and wireless mobility suffer. This replacement restores full cordless operation at a fraction of the OEM cost.
Each unit is pre-tested for voltage stability, charge/discharge cycling, and safety cutoff thresholds. Compatible across MAICO, Sanibel, and Amplivox MPT-II printer variants.
Key Features
- Li-ion Efficiency: 7.4V 1500mAh (11.1Wh) lithium-ion core delivers stable voltage from full charge to cutoff — no Ni-MH memory effect, no periodic deep discharge needed.
- 500+ Cycle Lifespan: Rated for over 500 full charge/discharge cycles, translating to 2-3 years of daily clinical use before replacement.
- Triple Protection PCB: Integrated circuit guards against overcharge, over-discharge, and short circuit — critical for equipment shared across multiple clinicians.
- Plug-and-Play: Drop-in replacement — no tools, no configuration. Remove the old pack, insert this one, charge fully, and resume printing.
- Pre-Charged for Storage: Ships at ~40% state of charge — the optimal storage level for lithium-ion cells — ensuring the battery arrives healthy and ready for its first full charge.
- CE / RoHS Certified: Meets international safety and environmental standards for medical facility procurement compliance.
- 1-Year Hassle-Free Warranty: If it fails under normal use within 12 months, we replace it — no forms, no delays.

About the MAICO MPT-II Thermal Printer
The MAICO MPT-II is a compact thermal printer widely paired with MAICO hearing screeners (such as the MAICO Ero-Scan and MAICO easyTone), diagnostic audiometers, and tympanometers in audiology, ENT, and occupational health clinics. It produces instant hard-copy test results — audiograms, tympanograms, and screening reports — that clinicians share with patients or file in medical records.
Because the MPT-II is battery-powered and highly portable, audiologists routinely carry it between exam rooms, off-site screening events, and school-based hearing test programs. A degraded battery that dies mid-print or refuses to hold charge directly disrupts patient flow and creates frustrating rework. Replacing the battery every 18-24 months is standard preventive maintenance for high-throughput audiology practices — and this replacement cell makes that refresh cycle affordable.
Frequently Asked Questions
-
Q: Is this an original MAICO battery?
A: No — this is a high-quality compatible replacement manufactured to OEM specifications. It is not MAICO-branded. -
Q: How long does a full charge last?
A: Under typical clinic use (intermittent thermal printing), a full charge supports 1-2 workdays. High-volume screening events will drain it faster. -
Q: Does the battery come with a charger?
A: No. The MPT-II printer charges the battery internally via its standard AC power adapter. Use your existing charger — no additional accessories needed. -
Q: Will this fit my Amplivox printer?
A: Yes, if your Amplivox unit uses the MPT-II thermal printer module. The battery is cross-compatible across MAICO, Sanibel, and Amplivox MPT-II variants. -
Q: How should I store spares?
A: Keep at 40-60% charge in a cool (15-25°C), dry location. Avoid storing fully charged or fully depleted for extended periods — this maximizes Li-ion lifespan.
Installation & Maintenance
- Installation: Power off the MPT-II printer, open the battery compartment (typically on the underside or rear), unplug the old battery, connect the new one, and close the compartment. Power on to verify the battery is recognized.
- First Charge: Charge to 100% before first clinical use (approximately 2-3 hours). The printer's status LED will indicate when charging is complete.
- Routine Check: Test runtime every 6 months. Print continuously from full charge and note when the low-battery indicator activates. Log the result for maintenance records.
- Replacement Cadence: Replace every 18-24 months in high-throughput clinics, or when runtime drops noticeably below a full workday.
- Cleaning: Wipe with a dry microfiber cloth. Do not use liquid cleaners, alcohol, or submerge the battery.
- Disposal: Lithium-ion batteries require specialized recycling. Return to an approved e-waste or battery recycling facility — never dispose of in general waste.
