Rechargeable Battery for Digital Blood Pressure Monitors

Description

The Welch Allyn BATT11 is an original one-cell lithium-ion rechargeable battery designed to power specific Welch Allyn diagnostic devices, most notably the Connex ProBP 3400 digital blood pressure monitor. It provides reliable 3.7 V DC power in a compact form factor and is intended as an OEM replacement battery, ensuring optimal performance, runtime and charging behaviour when used with compatible Welch Allyn equipment.

Bnefits

  • Original Welch Allyn lithium-ion battery designed specifically for compatible medical devices.
  • One-cell 3.7 V rechargeable power source matched to the power requirements of the Connex ProBP 3400 digital blood pressure monitor.
  • Helps ensure reliable operation and consistent performance versus non-OEM alternatives.
  • Compact, lightweight design suitable for handheld and portable clinical devices.
  • Intended for repeated charge and discharge cycles for routine clinical or home monitoring use.
  • Listed as the dedicated lithium-ion battery accessory for the Connex ProBP 3400 in Welch Allyn technical documentation.

Indications

  • Powering compatible Welch Allyn diagnostic devices that specify use of BATT11, primarily the Connex ProBP 3400 digital blood pressure monitor.
  • Use as a replacement battery when the original battery no longer holds sufficient charge or reaches end of service life.
  • Maintaining device availability in clinical environments by keeping charged spare batteries on hand.

Composition

  • Single-cell lithium-ion rechargeable battery pack (nominal 3.7 V).
  • Sealed battery housing designed for insertion in compatible Welch Allyn devices.
  • Integrated protection electronics (within the device’s charging and monitoring system) to manage charging and discharging safely.
  • Electrical terminals designed to mate with the Connex ProBP 3400 battery compartment contacts.

Formulation

  • One-cell lithium-ion (Li-ion) rechargeable battery pack engineered for use as the dedicated power source for the Welch Allyn Connex ProBP 3400 and other specified compatible devices.

Packaging

  • Supplied as a single OEM battery unit (BATT11) in manufacturer or distributor packaging.
  • Typically labelled with the Welch Allyn part number (BATT11) and basic electrical information (Li-ion, one cell, nominal 3.7 V).
  • Distributed individually for replacement use in compatible devices such as the Connex ProBP 3400.

Usage

  • Use only in Welch Allyn devices that explicitly specify compatibility with the BATT11 lithium-ion battery (for example, the Connex ProBP 3400 digital blood pressure monitor).
  • Insert the battery into the device’s battery compartment according to the polarity and orientation markings in the device instructions.
  • Charge the battery only via the compatible Welch Allyn device and/or approved Welch Allyn charging accessories; do not attempt to charge the battery directly or with unapproved chargers.
  • Do not short-circuit the battery terminals, disassemble, crush, puncture, incinerate or expose to excessive heat or open flame.
  • If the device shows significantly reduced runtime or difficulty holding charge even after full charging cycles, the battery may have reached end of life and should be replaced.
  • Follow local regulations and facility policies for disposal or recycling of used lithium-ion batteries.

Contraindications

  • Do not use in devices other than those specified as compatible by Welch Allyn or the device manufacturer.
  • Do not use if the battery casing is damaged, deformed, corroded, leaking or shows signs of overheating.
  • Do not expose the battery to water, high humidity or conductive contaminants that could cause short-circuiting.
  • Not intended for use outside approved medical devices or for any non-medical electrical applications.

Adverse Effects

  • If misused (e.g., short-circuited, overcharged, exposed to high temperatures, physically damaged), lithium-ion batteries can overheat, leak, vent or in extreme cases pose a fire or explosion risk.
  • In the event of leakage, contact with battery contents may cause skin or eye irritation; affected areas should be rinsed with plenty of water and medical advice sought if irritation persists.
  • When used according to manufacturer instructions within compatible devices, no specific adverse effects are expected for patients or users.

Storage Conditions

  • Store in a cool, dry place away from direct sunlight, heat sources and open flames.
  • Avoid temperatures outside typical lithium-ion storage ranges (for example, below 0 °C or above approximately 40 °C) to help preserve capacity and safety.
  • Do not store loose batteries in a way that allows the terminals to contact metal objects; keep in original packaging or a protective container.
  • For long-term storage, store partially charged rather than fully depleted, and check/refresh charge periodically in line with facility procedures.
  • Keep out of reach of children and unauthorised persons.

Duration

Not applicable. The battery serves as a power source and is used for the operational lifetime of the compatible device until it reaches end of service life.

Onset

Immediate electrical power delivery when correctly installed and sufficiently charged; enables normal operation of the connected device as soon as the device is switched on.
