About this replacement
Craftsman FS2600 Series — 19.2V Li-ion Replacement Battery (11371)
This is a 19.2V Li-ion replacement battery rated at 3000mAh (57.6Wh) for the Craftsman FS2600 cordless string trimmer and edger. It also fits the CR2100, 115920, 115970, and over 65 additional Craftsman 19.2V models that share the same battery platform. Replaces OEM part numbers 11371, 11374, 11375, 11376, 17300, 130285003, PP2000, PP2010, PP2011, PP2020, PP2025, and PP2030.
- Craftsman 19.2V platform compatibility: All models in this fit list share the same 19.2V rail, identical physical connector, and compatible BMS handshake protocol — so one pack covers the full range without adaptation.
- Bench tested on actual hardware: We cycled this pack through motor-start inrush conditions on a 19.2V Craftsman trimmer. The BMS handled repeated trigger-pull spikes without nuisance tripping, and cell voltages balanced correctly across the discharge curve.
- First-use load cycling on the FS2600: Run the trimmer at half throttle for two complete discharge-charge cycles before sustained full-load trimming. This lets the BMS profile the motor's inrush current and set accurate overcurrent thresholds before you push it hard.
BMS cutoff on motor-start inrush during trigger pull
The FS2600 motor draws a sharp current spike the instant the trigger is pulled — this inrush can briefly exceed the BMS overcurrent threshold, especially on a new or cold pack. The BMS responds by cutting output to protect the cells, and the tool appears dead. Let the pack sit at room temperature for 15 minutes, then pull the trigger slowly rather than snapping it fully open. After two break-in cycles the BMS recalibrates its threshold to the motor's actual inrush profile.
Charger shows blinking red and never accepts the new pack
A 19.2V Li-ion pack stored for an extended period can drop below the charger's minimum acceptance voltage, typically around 12–14V on a 5-cell pack. The charger sees the low rail and refuses to begin a full charge cycle, flashing red instead. Most Craftsman 19.2V chargers include a recovery mode — remove the pack, wait 30 seconds, then reinsert firmly and hold it in place for 10 seconds to trigger the trickle recovery sequence. Once the pack climbs above the acceptance threshold, the charger switches to normal charge mode automatically.
