How long will the battery last?

Typical battery life in the Oarlock is 10-25hrs, depending on the battery and ambient temperature. We recommend high quality Lithium disposables or Low Self Discharge rechargeable NiMH batteries for more economical use. We do NOT recommend use of alkaline batteries because they are prone to leaking, particularly in a humid environment, and A LEAKING BATTERY WILL DESTROY THE OARLOCK ELECTRONICS AND IS NOT COVERED UNDER WARRANTY! Here are some batteries we tested, along with the duration they ran under typical use at 75°F:

Energizer Ultimate Lithium 25hrs
Duracell Duralock Rechargeable 2500mAh 15hrs
Eneloop Pro Rechargeable 2450mAh 15hrs
Energizer Max Alkaline 15hrs (NOT recommended!)
Tenergy Rechargeable 2600mAh 14hrs
Energizer Power Plus Rechargeable 2300mAh 13hrs
Energizer Industrial Alkaline 13hrs (NOT recommended!)
Duracell Alkaline 1500mAh 11hrs (NOT recommended!)
Energizer Universal Rechargeable 1500mAH 10hrs
