Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

SumUp Air / AIR1E215 — 3.7V Li-ion Replacement Battery (DTS-1300-SW)
This is a 3.7V, 1200mAh Li-ion battery for the SumUp Air card reader (AIR1E215). It replaces OEM part DTS-1300-SW and fits directly into the Air's battery bay without any modification. When the original cell degrades and the reader dies mid-shift, this is the swap.
- SumUp Air and AIR1E215 fit: Both model variants use the same 3.7V cell, the same connector, and the same BMS handshake. One battery covers both SKUs.
- Bench tested on actual hardware: We ran this cell through full charge cycles on the SumUp Air and confirmed the BMS accepted the new cell without error flags. Charge IC entered normal CC/CV mode — no protection trip, no fault state.
- First-deployment calibration: After fitting the battery, complete one full transaction cycle before using the terminal in a live environment. The SumUp Air maps battery capacity during normal operation and needs at least one complete power cycle to register the charge indicator correctly.
SumUp Air rebooting mid-transaction after a battery swap
A fresh cell can trigger a BMS overcurrent trip if the terminal attempts a high-draw event — like a receipt print or wireless burst — before the protection circuit has settled. The BMS on a new cell starts conservatively and tightens the overcurrent threshold until it learns the load profile. This causes an unexpected reboot that looks like a firmware fault but is actually a protection event. Run two or three complete transaction cycles on the new battery and the trip threshold self-adjusts to normal operating current.
Terminal stuck at 99% charge and won't drop — new battery
This happens because the charge IC enters top-off mode on a new cell — it holds the cell at float voltage and the fuel gauge reports 99% rather than 100% until the first full discharge-recharge cycle completes. It is not a faulty battery or a faulty charger. Run the terminal down to the low-battery warning, then charge it uninterrupted to completion. After that cycle, the gauge re-anchors its 100% reference and reads correctly.

Frequently Asked Questions
My SumUp Air won't turn on at all after sitting unused for a few months — is the battery dead?
Most likely the cell has self-discharged below the BMS recovery threshold, which locks the battery out as a protection measure. Plug the terminal into charge and leave it for at least 30 minutes before attempting to power on — the charge IC needs time to trickle-charge the cell back above the recovery voltage (typically around 3.0V) before the BMS will allow a full boot. If the charge LED shows any activity, the cell is recovering. If there is no LED response after 45 minutes on charge, the original cell has failed and needs replacement.
SumUp Air restarted twice during back-to-back transactions — what's causing that?
Back-to-back transactions stack wireless, display, and card-read draw in rapid succession, and if the battery is degraded, voltage sag during that combined load pulls the cell voltage low enough for the BMS to trigger a protection cutoff. The terminal interprets this as a power fault and reboots. Check whether the restarts happen specifically during the receipt confirmation step — that is when the wireless module flushes the transaction data and draws peak current. A replacement cell with full capacity handles that load spike without sagging into cutoff range.
The SumUp Air completed its PCI boot sequence then shut off immediately on a new battery — why?
A new cell that ships at partial state of charge can sit just above the BMS minimum threshold. The boot sequence itself is a high-draw event, and pulling current for the PCI handshake can drop cell voltage enough to trip the low-voltage cutoff before the terminal reaches the home screen. Charge the battery fully before the first boot — connect to power and wait until the charge indicator shows complete, then power on. That gives the cell enough headroom to carry the full boot current without hitting the cutoff.
