AnswerLR14, C, E93, MN1400 are the supported exact aliases for one 26.2 × 50 mm cylindrical household cell. No other family is treated as an automatic replacement.
- Format
- Cylindrical household cell
- Dimensions
- 26.2 × 50 mm
- Voltage
- 1.5 V nominal (alkaline)
- Chemistry
- Alkaline manganese dioxide / zinc
- Drain context
- Product- and device-dependent
- Rechargeable?
- No — primary cell; do not recharge.
- Capacity context
- No universal family value; chemistry, load, temperature and cut-off alter service.
- Confidence
- High
Supported application context
- Household devices specifying this size and chemistry
Application context is limited to the scope stated in Energizer E93 Product Datasheet; it is not a device compatibility claim.
This record describes the alkaline version of the physical format. Rechargeable and lithium products may share a familiar size while using different voltage and charging requirements.
C/LR14 has a 50 mm-class height similar to AA but a substantially wider body. Its greater internal volume does not create one universal capacity across manufacturers, loads and cut-off voltages.
Commonly confused
What the code means
LR14 is the IEC-style alkaline identity for this household format; familiar consumer and manufacturer codes are retained as aliases.
Discharge and drain behaviour
Service life is device-, load-, temperature- and cut-off-dependent. A rechargeable or lithium product sharing the physical format is not the same electrical family.
Capacity context: No universal family value; chemistry, load, temperature and cut-off alter service.
Substitution guidance
Use the exact size and chemistry required by the device. Rechargeable NiMH and primary lithium products can share the familiar format while differing in nominal voltage and charging rules.
