Editing IBM PS/ValuePoint (section)

'''The PS/ValuePoint planar battery is a standard CR2032 lithium coin cell, NOT a NiCd barrel cell.''' This is important — the PS/ValuePoint does '''not''' suffer the destructive battery leakage that afflicts certain other IBM ISA-era systems (e.g. some PS/2 Models 30 / 56 / 57 / 76 / 77 with soldered NiCd).<ref>http://ps-2.kev009.com/pcpartnerinfo/ctstips/e1f6.htm</ref> The IBM "Product Description" repeats "Lithium battery" for every PS/ValuePoint variant including 6381 SX, 6381 DX/DX2, 6382/S, 6384/D, 6384 P60/D, and 6387/T.<ref>http://ps-2.kev009.com/pcpartnerinfo/ctstips/27ae.htm</ref>

The battery sits in a clip at position '''B1 / BT1'''. A separate '''J2 "External Battery" header''' and '''JP8 "Battery Select" jumper''' allows switching between the on-planar cell and an external battery wired off-board — useful for long-term storage of unused systems.<ref>http://ps-2.kev009.com/pcpartnerinfo/ctstips/a26e.htm</ref>

Although CR2032 cells very rarely leak, they '''can''' do so under unusual conditions; restorer field reports document a leaked CR2032 specimen pulled from a 6381-Fxx, with minimal damage to the planar.<ref>https://www.zx.net.nz/computers/ibm/psvaluepoint_425sxsi/</ref> Check the area around B1 / BT1 for KOH-style alkaline-leak residue at every service interval.
