Colin electrocardiographs usually use rechargeable nickel-metal hydride battery packs. Nickel-metal hydride batteries are a common secondary battery (rechargeable battery) that combines the advantages of nickel-cadmium batteries (Ni-Cd) and hydrogen energy technology. They have high energy density and are environmentally friendly. They are mainly composed of the following parts:

1. Positive electrode (cathode): The active material is nickel oxyhydroxide (NiOOH), which is converted into nickel oxide (Ni(OH)₂) after charging.

2. Negative electrode (anode): The active material is a hydrogen storage alloy (such as LaNi₅, MmNi₃, etc.), which is used to adsorb and release hydrogen atoms (H).

3. Electrolyte: Alkaline solution (usually KOH aqueous solution) that provides OH⁻ ion conduction.

4. Diaphragm: Prevents short circuit between positive and negative electrodes while allowing ions to pass through.

Features:

1. No memory effect: Compared with the old nickel-cadmium (Ni-Cd) battery, the memory effect of nickel-metal hydride battery is weaker and can be charged at any time without affecting the capacity.

2. Overcharge/over-discharge resistance: Medical equipment is usually equipped with intelligent charging management circuits to prevent overcharge or over-discharge and extend battery life.

3. Low self-discharge: The improved nickel-metal hydride battery has a low self-discharge rate and can maintain a high power level after being fully charged and stored for several months.

4. No harmful substances: It does not contain toxic metals such as cadmium (Cd) and lead (Pb), and meets the environmental protection standards for medical equipment (such as RoHS).

5. Long cycle life: It can be charged and discharged 500~1000 times (high-quality batteries). If used every day, the life span is about 2~5 years.

6. Low internal resistance: It supports instantaneous high current discharge (such as when the device is started or printed), and the voltage fluctuation is small.

7. Anti-leakage design: The sealed structure prevents electrolyte leakage from damaging the precision circuit.

8. Wide operating temperature range: Usually works stably at 0°C~40°C, suitable for different environments such as hospitals and emergency treatment.

9. High temperature tolerance: Better than lithium batteries, not easy to catch fire when short-circuited or at high temperatures (but long-term high temperatures will still accelerate aging).

Warning

1. Avoid exposing the battery to extreme temperatures, especially in high temperature and high humidity environments.

2. If the temperature is found to be overheated during use, please stop using it immediately and check it.

3. Avoid metal objects from contacting the positive and negative poles of the battery to prevent short circuits.

4. Check the appearance of the battery regularly. If there are abnormalities such as swelling and leakage, stop using it immediately and replace it.

5. Used batteries should be recycled according to regulations to avoid random disposal and pollution of the environment.

6. Do not use the battery beyond the rated current and voltage to prevent damage or danger.
