ECG replacement battery
Description
The Replacement Battery for Welch-Allyn CP100 ECG is a medical-grade sealed lead acid (SLA) battery designed specifically to power Welch Allyn CP100 electrocardiograph systems and other compatible devices that use OEM battery part 100660. It is supplied as a rechargeable valve-regulated lead acid (VRLA) pack with a nominal output voltage of 6.0 V and a rated capacity commonly specified as 6.0 Ah in distributor listings. The battery is intended as a direct biomedical replacement for the original CP100 internal battery, ensuring reliable performance, consistent ECG operation on battery power, and compatibility with the device’s internal charging circuitry. It is typically used in clinical environments to maintain portable operation of the CP100 ECG when AC mains power is not available, and is compatible with several aftermarket medical battery suppliers that meet or exceed OEM specifications for capacity, size and connectors.
Bnefits
Direct replacement for the original Welch Allyn CP100 ECG internal battery (OEM part 100660), ensuring correct fit and electrical compatibility.
Medical-grade sealed lead acid (VRLA) construction provides reliable, stable power delivery suitable for clinical ECG use.
Nominal 6.0 V output and rated capacity around 6.0 Ah provide sufficient runtime for routine ECG acquisition on battery power.
Maintenance-free VRLA design with immobilised electrolyte minimises leakage risk when used and handled correctly.
Designed to meet or exceed OEM specifications for performance and safety when installed and used according to device instructions.
Allows continued portable operation of the CP100 ECG during power outages, transport between rooms, or mobile clinics.
Relatively simple to replace as part of routine preventive maintenance by trained technical staff, extending the service life of CP100 devices.
Indications
Intended for use as a replacement internal battery for Welch Allyn CP100 electrocardiograph systems that specify OEM battery part 100660.
Suitable for maintaining or restoring battery-powered operation of the CP100 ECG in clinics, hospitals and other healthcare facilities.
Used during preventive maintenance when the original CP100 battery shows reduced runtime, fails self-tests or reaches end of service life.
In many aftermarket catalogs, also listed as compatible with Welch Allyn CP200 ECG and certain Lifesign models that use the same 6 V SLA pack; compatibility should always be verified against the device documentation and physical dimensions before installation.
Composition
Chemistry: Rechargeable sealed lead acid (SLA), valve-regulated lead acid (VRLA) type.
Electrodes: Lead (Pb) and lead dioxide (PbO2) plates.
Electrolyte: Dilute sulfuric acid (H2SO4) immobilised within a VRLA design.
Case: Impact-resistant plastic housing (commonly ABS or similar), enclosing the cells and terminals.
Terminals/connector: Medical battery connector suitable for CP100 ECG internal battery compartment (specific terminal style may vary by supplier but is matched to OEM 100660 interface).
Formulation
Battery type: Rechargeable VRLA/SLA medical battery.
Nominal voltage: 6.0 V.
Rated capacity: Typically specified as 6.0 Ah in replacement biomedical battery listings for CP100 ECG; some alternative compatible packs list 4.5–5.0 Ah, but the Medisave replacement battery is described as 6.0 Ah.
Chemistry: Sealed lead acid (VRLA).
Form factor: Block battery sized to fit the internal battery compartment of the Welch Allyn CP100 ECG (and compatible devices) with appropriate connector and orientation.
Typical physical dimensions from comparable 100660-compatible packs: approximately length 2.67 in (≈6.8 cm), width 1.77 in (≈4.5 cm), height 3.85 in (≈9.8 cm), though exact dimensions can vary slightly by supplier and should be verified against the existing battery before purchase or installation.
Intended use: Internal power source for electrocardiographs; designed for repeated charge/discharge cycles in medical environments.
Packaging
Supplied as a single sealed lead acid replacement battery pack per unit.
Packaged for protection during transport, typically in a cardboard carton with protective padding around the battery.
Labelling includes part number (100660 or equivalent cross-reference), chemistry, voltage and capacity information, along with manufacturer/distributor identification.
Shipped in accordance with regulations for lead-acid batteries, which may include specific labelling and documentation requirements.
Usage
Installation should only be performed by qualified biomedical engineers, service technicians or personnel trained to service Welch Allyn CP100 ECG devices.
Before replacing the battery, switch off the CP100 ECG and disconnect it from mains (AC) power.
Open the battery compartment according to the CP100 ECG service or user manual and carefully disconnect the existing battery from its connector, noting polarity and orientation.
Remove the old battery and install the new replacement battery in the same orientation, connecting the terminals/plug securely and ensuring there is no strain on the wiring.
Re-close and secure the battery compartment according to the manufacturer’s instructions.
After installation, connect the CP100 ECG to AC power and allow the battery to charge fully before relying on battery operation; refer to the CP100 directions for use for recommended charging times and battery conditioning procedures.
Perform any battery tests available in the CP100 service or user menu (e.g., battery life test) to confirm the new battery is recognised and performing correctly.
Use and charging thereafter should follow the CP100 ECG directions for use, including keeping the device connected to mains when practical to maintain charge and prolong battery life.
Do not attempt to open, modify or repair the battery pack; this can cause electrolyte leakage, fire or explosion.
At end of life, remove the battery from the device and dispose of it in accordance with local regulations for lead-acid batteries; do not dispose of in general waste.
Contraindications
Do not use this battery in any device other than those specifically designed to accept Welch Allyn 100660-compatible 6 V SLA packs (e.g., CP100 ECG and verified compatible models).
Do not install or use the battery if it shows signs of physical damage, cracking, swelling, leakage or corrosion.
Not suitable for use where a different chemistry or voltage is specified (e.g., lithium-ion upgrade batteries for CP100/CP200 that require different chargers and part numbers).
Do not expose the battery to open flame, high temperatures or direct heat sources that could cause rupture or explosion.
Do not short-circuit the terminals, reverse polarity during installation, or connect the battery to incompatible chargers or power systems.
Adverse Effects
If the battery casing is damaged and electrolyte leaks, contact with skin or eyes can cause irritation or chemical burns; affected areas should be flushed with plenty of water and medical attention sought immediately.
Incorrect installation, short-circuiting or overcharging can lead to overheating, venting or, in extreme cases, fire.
Use of a defective or depleted battery may result in CP100 ECG shutdown during patient testing, potentially interrupting ECG acquisition; devices should be checked for sufficient battery charge before use in situations where continuous monitoring is critical.
Lead-acid batteries present an environmental hazard if not disposed of correctly; improper disposal may contribute to environmental contamination.
Storage Conditions
Store the unused battery in a cool, dry, well-ventilated area away from direct sunlight and sources of heat.
Recommended storage temperature for sealed lead acid batteries is typically within approximately -15°C to +40°C, with optimal long-term storage around 15–25°C; extreme temperatures can reduce battery life.
Store in an upright position and protect from physical shock, vibration and mechanical damage.
Avoid short-circuiting the terminals during storage; keep terminals covered or isolated from conductive materials.
For prolonged storage, it is generally recommended that sealed lead acid batteries be recharged periodically (e.g., every 6 months) to prevent excessive self-discharge and sulfation; follow the battery supplier’s recommendations if long-term storage is anticipated.
Keep out of reach of children and unauthorised personnel.
