Jolog SRA07 Replacement Battery 14.4V 2600mAh Li-ion

Jolog SRA07 — 14.4V Li-ion 2600mAh Replacement Battery

This is a 14.4V Li-ion replacement battery for the Jolog SRA07 cordless vacuum cleaner. Capacity is 2600mAh (37.44Wh), matching the original cell specification. It restores power to vacuums where the original battery no longer holds a usable charge.

• SRA07 fitment: The SRA07 uses a 14.4V battery rail with a specific connector orientation and BMS handshake. This cell matches that voltage, connector, and communication requirement — the vacuum's power management circuit reads the battery state correctly on startup.
• Bench tested on actual hardware: We ran this battery through the SRA07's charge and discharge cycle. The BMS reported state-of-charge accurately at each stage, and the motor controller accepted the cell without fault codes or cutoff events under normal suction load.
• Dock charging habit: Do not leave the SRA07 sitting on the charging dock permanently. Continuous trickle charging degrades Li-ion cells faster than normal charge cycles. Charge to full, then remove the vacuum from the dock.

Suction dropping before the battery indicator reaches low

The SRA07 motor draws significantly more current when airflow is restricted — a partially blocked filter raises draw above the cell's rated output. The BMS responds by throttling power delivery to stay within safe limits, which the user experiences as weakening suction well before the indicator signals a low battery. The battery itself is not at fault. Check and clean the filter first — restored airflow reduces motor draw and the suction drop typically disappears.

Motor cutting out mid-clean and recovering after a few seconds

This is a BMS overcurrent trip, not a dead battery. When the motor sustains a high-draw state — usually caused by restricted suction from a blocked filter or a clogged brush roll — the BMS cuts power to protect the cell, then resets once current demand drops. The vacuum restarts as though nothing happened. Clear the blockage or clean the filter, then confirm resting cell voltage reads at or above 14.4V before assuming the battery is faulty.
