Most “dead” LP-E6 packs are really dirty contacts, cold cells or normal ageing. Run three quick checks before buying a replacement. Batteries are consumables. As cycle count rises, internal resistance increases and the pack shows full charge for less time, or shuts down abruptly in the cold. Work in order: clean the contacts, retest in a second body, then log the shot count from three full charges.
Key specifications and limits: 8K / 30 fps → LP-E6P / LC-E6 150 min. Actual figures vary with resolution, frame rate, screen brightness and ambient temperature, so plan spares around the shortest figure in the table.
Symptom checklist
The table lists four symptoms by how often they occur. In most cases a replacement is not yet necessary; rule out contact and temperature factors first.
| Symptom | Likely cause | What to do |
|---|---|---|
| Full charge drops to low very quickly | Oxidised contacts or an aged cell | Clean the contacts, retest in another body, then log full-charge shots |
| Body reports "cannot recognise this battery" | Third-party decoding mismatch or dirty contacts | Wipe and reseat; if it persists, test with an original-spec cell |
| Shuts down suddenly in the cold | Higher internal resistance causes a voltage dip | Keep spares warm in an inner pocket and retest at room temperature |
| Shell bulges or the pack runs hot | Overcharge, hot storage or aged cells | Stop using it immediately and recycle under local rules |
A three-step diagnosis
Step one: wipe the contacts with a dry soft cloth and reseat the pack. Step two: retest in a second body from the same family. Step three: log the shot count from three full charges to separate real ageing from a bad gauge.

When to replace the pack
Replace the pack when full-charge shots fall below about 60% of a new cell, the shell bulges, or the body repeatedly refuses to recognise it. Stop using a swollen cell immediately and recycle it properly.

FAQ
Does a jumping charge level mean the LP-E6 is dead?
Not necessarily. Clean the contacts, retest in a second body, then log the shot count from three full charges. Only a sustained drop in shots points to real cell ageing.
What if the camera says the battery is not recognised?
Dirty contacts or a third-party decoding mismatch are the usual causes. Wipe and reseat the pack; if it persists, test with an original-spec cell to separate a battery fault from a body fault.
Is fast drain in winter normal?
Yes. Cold raises internal resistance and causes a momentary voltage drop. Keeping spares in an inner pocket helps considerably, and capacity normally returns at room temperature.
When must the cell be replaced?
Replace it when full-charge shots drop below about 60% of a new cell, the shell bulges, it gets unusually hot while charging, or it is repeatedly not recognised. Never squeeze, puncture or recharge a swollen pack.
