About this replacement
Bissell Multireach 1318 / Bolt ION XRT — 18V Li-ion Replacement Battery (42330101062CE)
This 18V 2500mAh Li-ion battery replaces the original pack in the Bissell Multireach 1318, Multireach 1312, and Bolt ION XRT cordless stick vacuums. It matches the original voltage and capacity spec to keep suction consistent across cleaning sessions. Capacity figures are taken from the product data — 45Wh at 18V nominal.
- Multireach 1318, 1312, and Bolt ION XRT compatibility: These three models share the same 18V battery bay, connector pinout, and BMS communication protocol. The same cell pack and protection circuit fits all three without modification.
- Bench tested on actual hardware: We ran this battery through charge and discharge cycles on the Multireach platform. The BMS held the cutoff voltage correctly under simulated motor load and flagged over-discharge protection at the expected threshold without nuisance tripping.
- Dock charging habit on stick vacuums: Do not leave the vacuum sitting on the charging dock permanently. Cordless stick vacuums on continuous dock charge develop capacity fade significantly faster than those charged only when depleted. Charge to full, then remove the vacuum from the dock.
Suction dropping before the battery indicator reaches low on the Multireach
This is not always a battery fault. On the Multireach platform, a partially blocked filter forces the motor to draw more current than rated to maintain airflow. That elevated draw causes voltage sag under load, which the BMS reads as a low-state-of-charge condition — even when the cell is still at a healthy voltage. Clean or replace the filter first. If suction recovers, the battery was fine. If the pack still sags after a clean filter, check resting cell voltage — a healthy 18V Li-ion pack should read above 19V at rest after a full charge.
Motor cuts out mid-use and then recovers after a short pause
This is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked nozzle, saturated filter, or a jammed brush roll — the motor draws a sustained spike above the BMS current limit and the protection circuit opens the output. The pack recovers once current demand drops and the BMS resets. Clear the blockage, check the filter, and restart. If the trip keeps occurring on a clean, unobstructed vacuum, the cell pack may have degraded to a point where internal resistance is amplifying the current spike beyond what the BMS allows.
