1/26/16: Cybex and Hammer Strength HD SPARC console battery life explained. How long will the two D-Cell Alkaline Batteries in the console last?
Cybex Engineering tests showed average battery life is around 1,080 hours (45 days) straight at 24 hours a day which translates to:
- 1,080 days at 1 hour a day (close to 3 Years)
- 540 days at 2 hours a day
- 360 days at 3 hours a day
Average battery life is expected to be around 3 years. Recommended 18,000 mAh Alkaline batteries D-Cell Batteries:
- Energizer E95
- Energizer Max
- Duracell MN1300
- Duracell PC1300 Pro
- Panasonic LR20-D
The OEM batteries are all very high A/Hr (see above) where generic replacements will not be as good.
Note: Engineering did not test Lithium or Rechargeable batteries. Most rechargeable batteries are 1.2v (vs. 1.5v on an Alkaline battery) so their combined fully-charged starting voltage is only 2.4v and will likely trigger the LOW BATTERY message indefinitely.
