Suzuki Wagon R MH55S Mild-hybrid lithium-ion battery capacity
MH55S Type 1 versus Type 2: a smaller Wh figure is not an upgrade instruction
Applies to: Suzuki-hosted JARP recovery manual, December 2025 V2.3: pack label section pp.6–7; model table p.1; MH55S Type 1 sold through December 2019 p.26 and Type 2 sold from January 2020 p.13. Sale-period labels are the document’s wording, not Sri Lankan registration dates.
Keep the type and date boundary with the capacity
The recovery document separates the MH55S Type 1 application sold through December 2019 from Type 2 sold from January 2020. The published 120 Wh and 36 Wh entries are conditional pack references, not two freely interchangeable choices for the same car.
A later registration or import date does not establish which Japanese type was originally supplied. Have the actual vehicle and pack identification checked against the applicable documentation before comparing a replacement listing.

Wh and the lead-acid battery’s Ah answer different questions
The document explains that the lithium pack carries its capacity and manufacturing identification on a label. An energy figure in Wh must not be compared as if it were the conventional auxiliary battery’s Ah rating or used as a reason to substitute one chemistry for another.
This is a specialist recovery source, not an owner retrofit approval or evidence that fitting a smaller pack will work. No pack-opening or removal procedure is supplied here. Resolve the correct component and type with a qualified workshop; a change in a published energy figure alone does not diagnose the battery’s condition.
