General guidance for this part type - always follow your device manual- No tools required
- Check that the battery code printed on the old battery (for example BL-5C) matches the one on this listing.
- Wipe the phone's contacts with a dry cloth if the phone does not power on.
- 1Switch the phone off. Hold the power key until the phone shuts down. Never pull a battery from a phone that is still on.
- 2Remove the back cover. Press the release button or slide the cover off with both thumbs; on flip phones the latch is usually at the bottom of the back.
- 3Lift out the old battery. Use the small notch at the battery's edge. Note which end carries the gold contacts and which way the label faces.
- 4Fit the new battery. Line its contacts up with the spring contacts in the phone, slide that end in first and press the other end down until it lies flat.
- 5Close and charge. Refit the cover, switch on to check the phone powers up, then charge to full before regular use.
