Correctly selecting batteries for medical devices
In short: The device name alone is not enough. What matters are... Type number, voltage, capacity and design from the type plate of the existing battery. The same device type was delivered with different batteries over the years of production.
The four pieces of information that count#
| Information | Where she stands | Why it matters |
|---|---|---|
| Type or reference number | on the battery, often several separated by commas | most distinctive feature, such as 2056410-001 or MS29574 |
| Voltage in volts | Type plate | must match; common values are 3.7 to 14.8 V. |
| Capacity in Ah or Wh | Type plate | must be equal to or higher than, never lower |
| Dimensions and connection | Measure, look at the plug | The battery must fit in the compartment and make contact. |
An example from the product range: The battery for the GE MAC 2000 bears the reference numbers 2056410-001 and 2066261-013, operates at 14.54 volts and 3.50 Ah, which is 50.89 Wh, measures 99.6 × 53.8 × 41.7 mm and weighs 0.254 kg. Only this combination ensures a successful order.
Technologies in stock#
Four battery types are commonly used in medical technology. The type your device requires depends on the existing battery. Switching technologies is not a matter of choice, as the charging electronics and final charging voltage are specifically designed for each type.
| technology | Typical tension situation | Where it occurs |
|---|---|---|
| Lithium-ion | 3.7 to 14.8 V | newer patient monitors, ECG recorders, defibrillators |
| Nickel-metal hydride (NiMH) | 7.2 to 12 V | Monitors and pumps of mid-range manufacture |
| Nickel-cadmium (NC) | 4.8 to 12 V | older infusion and syringe pumps |
| Lead | 12 V and multiples | stationary devices, individual defibrillators |
Original or CE-compliant alternative#
We stock both. Original batteries bear the device manufacturer's name. Alternatives are marked as CE-compliant and list the reference number they replace. Both options require that the voltage, capacity, form factor, and connector match.
- Check whether defibrillators use a rechargeable battery or a primary battery. The lithium-manganese dioxide battery of a Lifepak CR2 is not rechargeable.
- For devices with a self-test function, the battery status is part of the documented operational readiness. Replace the battery before it expires, not after it fails.

Frequently Asked Questions#
- What information do I need to order the correct battery?
- Type or reference number, voltage in volts, capacity in Ah or Wh, as well as dimensions and connection type. This information is found on the existing battery. The device name alone is not sufficient, because the same device type was shipped with different batteries over the years.
- Can the capacity be higher than that of the old battery?
- Yes, provided the voltage, form factor, and connection remain the same. A higher capacity in Ah means a longer runtime. It must not be lower. The voltage must match in any case.
- What distinguishes an original battery from an alternative?
- The original battery bears the device manufacturer's name. Alternatives are marked as CE-compliant and display the reference number they replace. Both require the same specifications regarding voltage, capacity, form factor, and connection.
- Can I switch from nickel-cadmium to lithium-ion batteries?
- Not so easily. The device's charging electronics and charging voltage are specifically designed for the existing technology. Stick with the battery type specified by your existing battery, unless the device manufacturer specifies otherwise.
- Are all batteries in defibrillators rechargeable?
- No. Besides rechargeable batteries, there are primary batteries that are only used once, such as the lithium-manganese dioxide battery of the Lifepak CR2 or the M3863A battery for the Philips HeartStart range. Check the battery designation before connecting a charger.
- Do you also carry batteries for older devices?
- Yes. Our product range extends from current monitors to devices such as the Philips M3046 Viridia, Dräger Infinity Delta, and early B. Braun infusion pump models. Please provide the device type and reference number, and we will check the compatibility.
