SCANGRIP Miniform 03.5096 Replacement Battery 3.7V 1100mAh

SCANGRIP Miniform 03.5036 — 3.7V Li-ion Replacement Battery (03.5096)

This 3.7V 1100mAh Li-ion cell replaces OEM part 03.5096 in the SCANGRIP Miniform 03.5036 rechargeable work light. It matches the original cell's voltage and footprint, so it seats correctly without modification. When the original cell degrades and the light no longer holds charge, this is the direct swap.

• Miniform 03.5036 platform: The Miniform uses a single 3.7V Li-ion cell on a fixed-voltage driver circuit. Cell geometry matters here — the 40.30 x 36.40 x 8.60mm dimensions must match for the contacts to seat and the BMS to read the cell correctly.
• Bench tested on actual hardware: We ran this cell through the Miniform's charge cycle and confirmed the BMS accepted the cell without fault flags. The protection circuit engaged correctly at low-voltage cutoff, preventing deep discharge damage.
• Miniform storage tip: If the Miniform sits unused for several months, the onboard protection circuit may trip before the light ever powers on. Seat the new cell, connect the charger, and let it sit for 15 minutes before pressing the power button — this allows the BMS to initialise from a deep-sleep state.

Miniform dimming to low output before the indicator shows low battery

The Miniform's driver has brownout protection that steps output down when cell voltage drops below roughly 3.2V under load — even if the indicator hasn't triggered yet. This is intentional circuit behaviour, not a faulty cell. A degraded original cell hits this threshold faster because its internal resistance is higher, causing voltage to sag under draw. A fresh cell at full charge stays above that threshold longer, so the light holds its target output further into the discharge cycle.

New cell installed but Miniform won't power on at all

Li-ion cells shipped at storage charge — typically around 3.6V — can sit below the Miniform driver's minimum startup voltage after extended transit or storage. The protection circuit interprets this as an unsafe state and blocks output. Connect the Miniform to its charger immediately after installing the new cell. Once the cell reaches approximately 3.7V, the driver releases the lockout and the light powers on normally.
