![]() Which from the sounds of it, wasn’t a very high bar. By reverse engineering how the battery pack communicated with the computer, he reasoned he would be able to come up with an open source firmware that worked at least as well as what the the third party ones are running. Which is why decided to take the road less traveled and scratch built a custom battery for his ThinkPad T420. You can often get two or three of the knock-offs for the same price as a single real battery, but they never last as long as the originals. Which means you also know how much legitimate OEM packs cost compared to the shady eBay clones.

Remote Industrial Sensors (e.g., Meters, Alarms).Low Power Primary Battery Powered Systems (e.g., 1× LiSOCl 2, 2–3× Alkaline).The LTC3337 is offered in both 12-lead 2mm × 2mm LFCSP and 16-ball 1.64mm × 1.64mm WLCSP packages. To accommodate a wide range of primary battery inputs, the peak input current limit is pin selectable from 5mA to 100mA.Ĭoulombs can be calculated for either the BAT_IN or BAT_OUT pin, determined by the AV CC pin connection.Ī BAL pin is provided for applications utilizing a stack of two supercapacitors (optional) at the output. The LTC3337 also integrates additional SOH monitoring which measures and reports via I2C: battery voltage, battery impedance, and temperature. Coulomb counter accuracy is constant down to no load. When it is reached, an interrupt is generated at the IRQ pin. A discharge alarm threshold based on this state of charge (SOC) is programmable. The patented infinite dynamic range coulomb counter tallies ALL accumulated battery discharge and stores it in an internal register accessible via an I 2C interface. It is designed to be placed in series with a primary battery with minimal associated series voltage drop. The LTC3337 is a primary battery state of health (SOH) monitor with a built-in precision coulomb counter.
