Lightweight and compact, it ensures your BIOS settings like date and time remain accurate, preventing boot errors and system glitches. Ideal for HP 820 G1 and 640 G1 models, this battery is a must-have replacement every 3-4 years to maintain optimal laptop performance. ## Description Always got wrong date and error message when you turn on your laptop? Even the Windows XP can't be loaded correctly? (Windows XP can't be loaded correctly when the Date setting is no sense, this could happen when the CMOS battery voltage is low). Then it is time to change your CMOS RTC coin battery! Every computer has a small coin cell battery to power the BIOS chip to keep the date, and other internal settings effective. Without these cmos batteries or a dead cmos battery these internal setting will not function. CMOS RTC battery should be replaced every few years (typically 3-4 yrs). ## Features - Battery Size:CR2032 - Connector: 2 Pins & 2 Wire - Cable Length:2 inch(Including the Connector Length) - Connector Pitch:1.0mm - Compatible Model:All Coin-cell BIOS battery with 2 Pins 2 Wire,1.0mm Pitch ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08PRYPHKM | | Antenna Location | Laptop | | Battery Capacity | 220 Amp Hours | | Battery Cell Type | Lithium Manganese Dioxide | | Battery Weight | 4 Grams | | Best Sellers Rank | 94,515 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 1,904 in Laptop Batteries | | Brand Name | LeFix | | Compatible Phone Models | For Laptop | | Customer Reviews | 4.3 4.3 out of 5 stars (121) | | Item Dimensions | 45 x 20 x 3 millimetres | | Item Weight | 9 Grams | | Model Name | cr2032 | | Model Number | 820 G1 640 G1 | | Number of Batteries | 1 CR2 batteries required.
