If your Lenovo Chromebook S345-14AST<\/a> is no longer holding a charge like it used to, replacing the battery is a practical solution. However, searching for a replacement can be confusing, as you will likely come across three very similar part numbers: L18D3PG2<\/a>, L18M3PG2<\/strong>, or L18L3PG2<\/strong>.<\/p>\n\n\n\n

Which part number should you choose?<\/p>\n\n\n\n

Decoding the Part Numbers<\/h2>\n\n\n\n

In reality, these batteries are completely identical in terms of performance. All three options are 3-cell lithium-ion batteries designed specifically for the S345-14AST. They share a total capacity of around 57Wh<\/strong> and a nominal voltage of approximately 11.5V<\/strong>, meaning they are built for the exact same chassis.<\/p>\n\n\n\n

The only difference lies in the middle letter (D<\/strong>, M<\/strong>, or L<\/strong>). This code indicates the Original Equipment Manufacturer (OEM) that produced the battery cells for Lenovo’s production line. Lenovo relies on this multi-vendor strategy to ensure supply chain stability. If one factory experiences a shortage, another can immediately step in to fill the gap.<\/p>\n\n\n\n

The Crucial Difference: Cable Length<\/h2>\n\n\n\n

While these three models share identical technical specifications, they all come in both “long cable”<\/strong> and “short cable”<\/strong> versions.<\/p>\n\n\n\n

Important:<\/strong> When purchasing a replacement battery, you must check the cable length of your original battery first. The new cable must match the exact length of the one already inside your laptop.<\/p>\n\n\n\n

A mismatched cable can lead to installation issues, put excessive strain on the connector, or cause an unstable power supply.<\/p>\n\n\n\n
