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,

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.

Samsung Galaxy Y GT-S5360 — 3.7V Li-ion Replacement Battery (EB454357VU)

This 3.7V, 1350mAh Li-ion cell replaces the original EB454357VU battery in the Samsung Galaxy Y and its variants. It fits the GT-S5360, GT-S5380, GT-S5380D, and 18 additional models sharing the same battery bay and connector spec. Voltage and capacity match OEM figures exactly.

  • Galaxy Y platform fit: The GT-S5360, GT-S5380, and related variants all draw from the same 3.7V single-cell architecture with an identical connector and battery bay footprint. One cell covers the full range without modification.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a GT-S5360 unit. The BMS accepted the charge handshake immediately, and the protection circuit tripped correctly at low-voltage cutoff — no negotiation errors on either end.
  • Fuel gauge recalibration on first use: On first installation, disable any fast-charge mode and run one full discharge-to-charge cycle before normal use. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve, preventing erratic percentage readings from the first week onward.

Why the Galaxy Y reports the wrong battery percentage after a cell swap

The GT-S5360 uses a fuel gauge IC that builds its charge model from the discharge history of the installed cell. When you swap in a new cell, the IC still holds calibration data from the old, degraded battery. Until it re-learns the new cell's voltage-to-capacity curve, the displayed percentage drifts from actual charge state. One full uninterrupted discharge down to auto-shutoff, followed by a complete charge to 100%, resets the coulomb counter against the new cell. After that single cycle, percentage accuracy stabilises.

Sudden shutdown at 20–30% on the replacement cell

This is a voltage cliff issue, not a capacity defect. When the modem transmits or the screen brightness spikes, instantaneous current draw pulls the cell voltage below the BMS cutoff threshold — even though the fuel gauge still shows charge remaining. It happens most often when the fuel gauge IC hasn't yet calibrated to the new cell's internal resistance profile. Run one full discharge cycle and check that the cutoff doesn't repeat. If the phone still shuts down before 15%, measure resting cell voltage with a multimeter — it should read above 3.6V at the reported 25% level.

Frequently Asked Questions

The Galaxy Y won't turn on at all after the replacement battery sat in a drawer for a few months — is it dead?

A cell stored in a discharged state can drop below 2.5V, which triggers the BMS lockout to prevent damage. The phone won't respond to the power button because the protection circuit has cut output entirely. Plug it into a wall charger — not a USB port — and leave it for 20–30 minutes before attempting to power on. If the charging LED doesn't activate within that window, the cell voltage may be too low for the charge IC to recover; try a different charger with a higher standby output to push past the BMS wake threshold.

The phone feels warm near the battery slot during the first charge — is something wrong with the new cell?

Mild warmth on the first charge cycle is normal when a new high-impedance cell takes its initial current. A fresh Li-ion cell has slightly higher internal resistance before it's been cycled, which generates more heat than a broken-in cell would. If the phone is only warm — not hot — and the temperature drops on subsequent charges, no action is needed. If it stays hot after the second full charge, check that no debris is trapped between the battery and the cover compressing the cell, and confirm the charger output matches the OEM spec of 5V.

Fast charging stopped working after I put in the new battery — the phone now charges slowly every time.

The charge IC on the GT-S5360 re-negotiates the charge protocol each time a new cell is detected. On the first cycle with a replacement battery, the IC often defaults to a conservative trickle rate until it confirms the BMS is responding correctly. Remove the battery, reinsert it firmly so the contacts are fully seated, then reconnect the charger. If standard charge rate doesn't resume after one complete cycle, check that you're using the original Samsung wall adapter — third-party chargers often fail the handshake and lock the IC into slow-charge mode permanently.
