Customer feedback is generally favourable about battery quality, reliability and value, and mentions successful use with inflatable mattresses. Battery life is a mixed point, so buyers choosing cells for equipment that must run for a predictable duration should account for that uncertainty. The listing gives no runtime figure, and its five-year claim concerns shelf life rather than in-device performance.
Positive themes
- Customer feedback describes the batteries as good quality and good value.
- Customers report that they function well, including with inflatable mattresses.
Mixed feedback
- Feedback is mixed on battery life during use.
