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.

Apple iPod 4th Generation — 3.7V Li-Polymer Replacement Battery (616-0183)
This 3.7V, 900mAh lithium-polymer battery replaces the original cell in the Apple iPod 4th Generation, including models A1059, A1099, and the Photo 30GB M9829. It fits the same physical footprint at 51.13 x 33.84 x 4.10mm and connects to the same flex-ribbon power connector on the logic board. Capacity matches OEM spec — no inflation, no rounding up.
- A1059 and A1099 platform fit: Both model numbers share the same logic board revision, power connector pinout, and 3.7V nominal rail. The BMS on each accepts the same charge termination voltage, so one cell covers both variants without modification.
- Bench tested on actual hardware: We ran this cell in an A1059 unit and confirmed the BMS accepted charge current normally, balanced to full without tripping protection, and discharged across the full voltage window without premature cutoff.
- Post-install first charge: If the player has been stored flat for weeks or months, connect it to a charger and leave it for 30 minutes before pressing any buttons. The iPod 4th Generation enters a deep-discharge protection state that requires a slow trickle before normal charge current is accepted.
Battery percentage jumping after a cell swap on the iPod 4th Generation
The iPod 4th Generation reads battery level by mapping a voltage curve — not by coulomb counting. After a new cell is installed, the device has no charge history to reference, so the percentage readout can jump or drop suddenly during the first few cycles. This is the voltage-threshold indicator recalibrating to the new cell's discharge curve. Run the battery from a full charge down to automatic shutoff two or three times without interruption. After two to three full cycles, the percentage display tracks the actual charge state accurately.
Playback cuts out before the battery indicator shows empty
The audio amplifier in the iPod 4th Generation draws a voltage spike during playback — particularly at higher volume levels — that the end-of-discharge cell cannot sustain. When the cell voltage sags below roughly 3.2V under that load, the BMS cuts output to protect the cell, even if the on-screen indicator still shows a bar or two remaining. This is not a fault with the replacement cell — it is the BMS responding correctly to load-induced sag. Avoid running playback at maximum volume when the battery is below 20% to reduce the frequency of these cutoffs.

Frequently Asked Questions
My iPod 4th Generation won't turn on at all after sitting in a drawer for months — is the battery dead?
Probably not dead, but likely in deep-discharge protection. Connect it to a charger and leave it alone for at least 30 minutes before pressing the Menu or Select button. The iPod's BMS blocks normal charge current when the cell drops below a threshold voltage, so it needs a slow trickle to recover first. If the screen shows nothing after 30 minutes, try a different cable or USB power source — the trickle draw is low enough that a weak charger may not register.
The battery percentage on my iPod 4th Generation jumps from 40% straight to 5% and then shuts off — what's happening?
This is a voltage-curve recalibration issue, common after any cell swap. The iPod maps percentage to voltage thresholds, and a fresh cell with no discharge history throws that map off. Run the player from a full charge down to automatic shutoff without plugging it in mid-cycle — repeat this two to three times. After those full cycles, the indicator recalibrates to the new cell's actual curve and the jumps stop.
Audio cuts out mid-song even though the battery still shows a charge — is the new cell faulty?
The cell is likely fine — this is voltage sag under amplifier load. Near end of discharge, the cell voltage drops when the audio amplifier demands current, especially at higher volume. That sag triggers the BMS cutoff before the indicator reads zero. Keep volume below 75% when the battery is low and the cutouts will reduce significantly. If it happens consistently at full charge too, check that the battery connector on the logic board is fully seated.
