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.

Dell PowerEdge 2600 / 2650 Series — 3.7V Li-ion RAID Controller Battery (1K178)
This is a 3.7V, 1800mAh Li-ion replacement for the RAID controller backup battery in Dell PowerEdge 2600, 2650, PE1650, and PE2600 servers. It powers the controller's cache during unexpected power loss, giving the RAID module time to flush in-flight writes to disk. Cross-references include OEM part numbers 1K178, LI103450E, FDL00-150137-0, 1K240, 7F134, Y0229, C0887, and 13JPJ.
- PowerEdge RAID controller compatibility: These PowerEdge models share the same PERC controller architecture and use the same 3.7V single-cell backup battery with an identical connector and BMS handshake profile. Swapping between 2600 and 2650 variants does not require any hardware modification.
- Bench tested on actual hardware: We ran this cell through charge, discharge, and BMS communication cycles on a PERC controller. The BMS negotiated correctly, reported cell voltage within the expected acceptance window, and flagged no fault codes during the test sequence.

Learn cycle initiation after swap:
After fitting this battery, trigger a learn cycle from the controller management interface — StorCLI:
/cx bbu start learn, or check status via/cx bbu show. The controller holds write-through mode until the learn cycle completes and the backup window estimate is recalibrated against the new cell's actual capacity.
RAID controller staying in write-through mode after battery swap
Write-through mode is not a fault — it is the controller protecting your data while it has no verified backup window. After a battery swap, the PERC controller does not automatically trust the new cell. It waits for a completed learn cycle before switching back to write-back mode. The learn cycle typically takes 24–72 hours under normal server load. If the cycle is still pending after 72 hours, confirm the battery is seated fully and run StorCLI /cx bbu show to check learn cycle state and current cell voltage — expected resting voltage is approximately 3.6–3.7V.
Management console reporting a battery error days after installation
The PERC controller runs its battery self-assessment on a timed schedule, not at boot or at the moment of installation. This means a newly installed cell may pass initial connection checks but still trigger a battery error when the first scheduled assessment runs — sometimes 24–48 hours later. The error usually clears on its own once the learn cycle has finished and the controller has logged a full charge-discharge recalibration. If the error persists past 72 hours, pull the current learn cycle status with /cx bbu show all and verify that "Learn Cycle Active" reads "Yes" and cell voltage is holding above 3.5V.

Frequently Asked Questions
My PowerEdge 2600 RAID controller switched back to write-through mode right after I installed the new battery — is the cell faulty?
The cell is almost certainly fine. The PERC controller defaults to write-through mode any time it cannot confirm a verified backup window, and a freshly installed cell has no calibration history yet. The controller needs a completed learn cycle — typically 24–72 hours under normal load — before it will switch back to write-back mode. Trigger the cycle manually with `StorCLI /cx bbu start learn` and confirm the cell voltage sits between 3.6V and 3.7V at rest.
The BIOS self-test shows the backup window as much shorter than expected — the original battery lasted far longer before replacement was flagged.
Backup window estimates are calculated against the cell's calibrated capacity, and a new cell won't match the OEM figure precisely until it has completed two or three full learn cycles. The controller recalculates the window after each cycle, so the estimate will stabilise over the first few charge-discharge passes. This is not a cell defect — it is the BMS settling its model of the new cell. Check the figure again after the third learn cycle completes using `StorCLI /cx bbu show` and compare the "Design Capacity" versus "Full Charge Capacity" fields.
The RAID controller battery is reporting a failed self-test even though I just installed the replacement cell an hour ago.
The PERC controller's battery self-test runs on a fixed schedule, not on demand at installation. A self-test failure logged within the first few hours almost always means the assessment was triggered mid-cycle before the new cell had reached a stable charge state. Let the server run for 24 hours, allow the cell to reach a full charge, then manually initiate a learn cycle with `StorCLI /cx bbu start learn` — the next scheduled self-test will run against the calibrated cell and should clear the fault.
