Detailed Answer
For 8 hours/day warehouse work: lithium version (LDER LD series) 5-10 days, NiMH 3-7 days. Standby power draw is at µA level (sleep design). Recommendation: check battery level each shift, replace when the low-battery alarm sounds, rotate 2 batteries. In cold storage, NiMH runtime shrinks (low temperature), so double the spare batteries.
| Lithium | 5-10 days |
| NiMH | 3-7 days |
| Cold storage | Double spares |
Note:Include battery checks in the shift handover routine.
