4
+The CR1220 is a lithium coin cell battery with the following key features:
5
+
6
+Specifications:
7
+- Diameter: 12 mm
8
+- Thickness: 2.0 mm
9
+- Nominal Voltage: 3V
10
+- Capacity: Approximately 35-40 mAh (varies by brand)
11
+- Chemistry: Lithium Manganese Dioxide (LiMnO2)
12
+- Operating Temperature Range: -30°C to +60°C
13
+
14
+Common Applications:
15
+- Watches
16
+- Calculators
17
+- Car key fobs
18
+- Small medical devices (like glucose meters)
19
+- Motherboards (for CMOS memory)
20
+- Small toys
21
+
22
+Advantages:
23
+- Long Shelf Life: Typically 5-10 years due to low self-discharge rates.
24
+- High Energy Density: Ideal for compact devices.
25
+- Stable Voltage Output: Ensures consistent device operation.

28
+## Pulse Current
29
+
30
+The CR1220 lithium coin cell battery is designed for low-power devices, and its discharge current specifications depend on the manufacturer and application. Here's an overview:
31
+
32
+1. Continuous Discharge Current
33
+- Typical Range: 0.1 mA to 0.2 mA
34
+- This current is sufficient for steady operation in devices like watches, calculators, and small sensors.
35
+
36
+1. Maximum Pulse Discharge Current
37
+- Typical Range: 1 mA to 5 mA (varies by brand)
38
+- The battery can briefly supply higher currents for short bursts, such as transmitting signals in key fobs or powering small LEDs.
39
+
40
+### Important Notes:
41
+
42
+Overloading the Battery:
43
+
44
+If the discharge current exceeds the specified range for a long time, it may cause:
45
+- Sudden voltage drop
46
+- Reduced capacity
47
+- Battery heating or leakage
48
+
49
+Brand Variation:
50
+
51
+Manufacturers like Panasonic, Sony, or Maxell may have slightly different specifications for their CR1220 batteries. Always check the datasheet for the specific brand you're using.
52
+
53
+### Recommendations:
54
+
55
+If your device requires higher discharge currents (e.g., above 10 mA), consider:
56
+
57
+Adding a Capacitor: To handle short bursts of high current.
58
+Using a Larger Battery: Such as CR2032 or CR2450, which are better suited for higher-power applications.
