Janam XM5 Barcode Scanner Replacement Battery 3.7V 3600mAh

Janam XM5 / XM70 / XM70XP / XP Series — 3.7V Li-ion Replacement Battery

This 3.7V, 3600mAh Li-ion cell replaces the factory battery in the Janam XM5, XM70, XM70XP, and XP Series rugged handheld scanners. These devices are used in warehousing, retail stockrooms, and logistics environments where continuous shift coverage matters. Capacity figure is 13.32Wh as rated from the pack.

• XM5, XM70, XM70XP, and XP Series fit: These models share a common 3.7V battery platform, the same physical footprint, and a compatible BMS handshake. One pack covers the full line without modification or adapter.
• Bench tested on actual hardware: We ran the pack through charge-discharge cycles on an XM Series unit and monitored BMS response under combined scan-trigger and wireless radio draw. Cell voltage held stable through repeated burst-scan sequences and the BMS did not trip on inrush.
• First-shift preparation for pick-and-pack environments: After installing this pack, seat the scanner in its cradle and run a full charge cycle before using it on the floor. Scan-trigger inrush current peaks when the cell is near minimum, and a depleted new pack can cause a false BMS trip on the first burst scan of the shift.

Cradle showing a charging error on a freshly installed pack

Charging errors on new packs in the XM Series cradle are almost always a contact resistance issue, not a fault with the cell itself. Oxidation or debris on the battery contacts raises resistance above the dock's threshold, and the charger reads that as an abnormal pack. Wipe the gold contacts on both the battery and the cradle with a dry lint-free cloth, then reseat the pack firmly until you feel it click. If the error clears, the cell was fine — the contact surface was the problem.

Scanner losing wireless connection during a rapid scan burst

On the XM Series, the scan trigger and the wireless radio draw current at the same time during a fast scan burst. If the cell is aged or at low state of charge, that combined inrush causes a momentary voltage sag that drops below the radio module's minimum operating voltage. The scanner stays on but the wireless link drops for one to three seconds before recovering. Keeping the battery above 3.5V during heavy scanning prevents this — charge the pack between pick waves rather than running it to the low-battery warning.
