Up to 17% off
New arrival
From $133.99 USD $160.99
Shipping calculated at checkout.
Fits Dell Inspiron 1300, Inspiron B120, and B130 notebooks — replaces OEM part numbers 312-0416, HD438, KD186, and XD187.
11.1V and 8800mAh capacity delivers 97.68Wh of charge — sufficient for typical office work and web sessions on this ultraportable.
Connector slides straight into the battery bay slot with a single locking tab — no modifications needed, seats flush against the palmrest frame.
We ran a full charge and load cycle on the Dell firmware — BMS reported nominal voltage under draw with no early cutoff signals or cell imbalance flags.
After installation, discharge fully to hibernation cutoff then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears the inaccurate health warnings that appear after every cell swap on this model.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,
Michael

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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

🔹 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 Inspiron 1300 / B120 / B130 — 11.1V Li-ion Replacement Battery (312-0416)

This is an 11.1V Li-ion battery rated at 8800mAh (97.68Wh), built to fit the Dell Inspiron 1300, Inspiron B120, and Inspiron B130 notebooks. It replaces OEM part numbers 312-0416, HD438, KD186, and XD187. If your original cell no longer holds charge or the laptop won't run unplugged, this is the direct swap.

  • Inspiron 1300, B120, and B130 compatibility: These three models share the same battery bay dimensions, 11.1V power rail, and connector pinout. The BMS on each platform uses the same charge handshake, so one cell covers all three without modification.
  • Bench tested on actual hardware: We cycled this cell on an Inspiron 1300 chassis. The BMS accepted the charge handshake on first contact, balanced across all cells without fault codes, and held voltage through a full discharge to hibernate cutoff.
  • Post-install calibration on Dell Inspiron platforms: After fitting, run one full discharge to hibernate cutoff, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.

Why the Inspiron 1300 shuts down at 20–30% after a battery swap

The Dell BIOS tracks a voltage-discharge curve learned from the original cell. A new cell with different internal resistance shifts that curve, so the fuel gauge IC misreads remaining capacity under load. When the CPU and display draw full power together, the cell voltage drops faster than the old curve predicted, triggering a hard shutdown before the gauge reaches zero. Running two to three full discharge-recharge cycles teaches the fuel gauge IC the actual curve of the new cell and eliminates the early cutoff.

BIOS reporting battery health as "poor" or "unknown" right after fitting a new cell

The BIOS reads health data from EEPROM registers carried over from the previous cell, not from the new one. Until a battery learn cycle runs, those stale registers report degraded values against the new chemistry. Boot into the Dell BIOS setup, navigate to the battery health screen, and confirm the learn cycle has not been locked by the old cell's wear flags. Complete one full discharge to hibernate cutoff followed by an uninterrupted charge to 100% — the BIOS will update its health status once the new cycle data overwrites the old EEPROM values.

Frequently Asked Questions

The Inspiron 1300 shows a wildly different battery percentage every time I check — jumps from 60% to 15% with no warning. Is the new battery faulty?

The fuel gauge IC on these Dell boards calibrates its percentage readings against discharge data from the installed cell. A brand-new cell has no learned curve yet, so the IC interpolates badly and produces erratic readings. This is not a cell fault. Run two full discharge cycles — drain to hibernate cutoff, then charge uninterrupted to 100% each time — and the gauge will stabilise to within a few percent of actual remaining capacity.

System information shows the wrong Wh rating for this battery — it lists a lower figure than the 97.68Wh on the product page. What's happening?

The Wh figure displayed in Windows or the Dell BIOS is pulled from EEPROM data written to the cell at manufacture, which reflects rated chemistry values rather than the measured capacity of the physical cells. The 97.68Wh on the product page is the actual cell capacity. The discrepancy is a read-out difference, not a capacity shortfall — the battery delivers its full rated energy regardless of what the EEPROM register reports.

The Inspiron B130 charges fine but stops at 80% and won't go higher — charger is connected and light is green.

Dell BIOS on several Inspiron-series boards includes a firmware-controlled charge limit that caps charging at 80% to reduce long-term cell wear when the laptop is kept plugged in. This is a BIOS setting, not a fault with the replacement cell. Open the Dell Power Manager application or enter BIOS setup, locate the battery charge configuration option, and switch from "Primarily AC" or "Custom" mode to "Adaptive" or "Standard" — the charge ceiling will reset to 100%.
