Designing a Cell for Ten Years, Not Five Hundred Cycles
Calendar ageing and cycle ageing are separate budgets. For idle-dominant products, storage voltage and cell temperature decide the outcome, and oversizing plus partial-SoC float is the practical fix.
Read article →Storage State of Charge: What Happens to Cells in Your Warehouse
A cell sitting in a box is still ageing. How fast depends almost entirely on two numbers you control: its state of charge and the temperatur
PSE, KC and BIS: The Certifications IEC 62133 Does Not Cover
IEC 62133-2 gets you a test report. Japan, Korea and India each want something more before your product clears customs — and each has a lead
Picking a C-Rate: Why Your Cell Runs Hot at Spec
Capacity sizing tells you how big the cell is. C-rate sizing tells you whether it survives the load. The two are different calculations and
Choosing Connectors and Harnesses for a Custom Li-Po Pack
Pitch, current rating, polarity protection, wire gauge and strain relief — the interface between a custom cell and your board, and the five
How to Read a Li-Po Datasheet Without Getting Burned
Every number on a lithium polymer datasheet was measured under conditions the sheet may not print. Here is what each line actually promises,
CR2032 vs LIR2032 vs ML2032: A Head-to-Head Coin Cell Comparison
Three families share the 20 mm coin form factor but solve different problems. A practical side-by-side on voltage, capacity, cycle life, ref
How to Choose Li-Po Battery Capacity for IoT Devices
A practical guide for hardware engineers selecting polymer lithium cells for low-power IoT applications.
IEC 62133-2:2017 + Amendment 1: The Complete Test Walkthrough
A compliance lead's plain-English guide to every mandatory and conditional test in IEC 62133-2, with cost estimates, timelines and how it fi
Stepped and L-Shaped Batteries: Geometry Guide for Wearable Electronics
Why rectangular cells do not fit modern wearable enclosures, and how stepped, L-shaped and U-shaped geometries work — including electrode co
