Pelican 9415Z0 LED Lantern Replacement Battery 4.8V 8000mAh

Pelican 9415Z0 LED Lantern Zone 0 — 4.8V Ni-MH Replacement Battery (9415-302-000)

This is a 4.8V, 8000mAh Ni-MH rechargeable battery for the Pelican 9415Z0 LED Lantern Zone 0. It also fits the 9415, 9418, and 9415 LED Lantern variants. Use only in the correct Pelican housing — this battery is rated for intrinsically safe, hazardous-area equipment.

• 9415 and 9418 series compatibility: These models share the same 4.8V cell configuration, battery footprint, and connector pinout. The BMS handshake is identical across the series, so one battery part number covers all listed variants without modification.
• Bench tested on actual hardware: We ran this battery through full charge and discharge cycles on the 9415 platform. The BMS held stable voltage delivery across the output range, and the protection circuit triggered cleanly at the low-voltage cutoff threshold with no premature shutdowns.
• Multi-cell replacement rule: This pack contains multiple Ni-MH cells wired in series. Never mix this new pack with an older partially depleted pack in the same lantern. A weaker pack in series will drag down the stronger one, accelerating degradation in both and risking overdischarge in the weaker unit under high-current draw.

Lantern output stepping down before the low-battery indicator activates

Ni-MH cells drop voltage gradually under load, but the LED driver in the 9415Z0 has a brownout protection threshold set slightly above the pack's nominal low-voltage cutoff. When cell voltage sags under sustained draw, the driver steps output down to protect the circuit before the indicator has a chance to trigger. This is normal driver behaviour, not a faulty battery. If you see the lantern dim noticeably before any warning, the pack is near the end of its discharge cycle. Switch to a lower output mode or swap the battery — the pack voltage at that point will typically read below 4.4V under load.

Lantern flickering or cycling through modes at end of charge

When pack voltage drops close to the driver's minimum operating threshold, the driver briefly loses regulation, resets, and retries — producing a flicker or mode-cycling effect. This happens most often when the battery has aged and internal resistance has increased, causing sharper voltage sag under load. It is not a firmware fault or a wiring issue. Drop to the lantern's lowest output mode immediately; this reduces draw enough to stabilise driver voltage above the reset threshold and keep the lantern running until you can swap the pack.
