Review on π Tenergy Rechargeable 9V NiMH Batteries (4 Pack) - High Capacity 250mAh for Smoke Detector/Alarms, TENS Unit, Metal Detector, and More by Marcel Snoddy
They do their job UPDATE: Actually NO, they've never done it before. e 3 out of 4 rubbish.
There are 2 green/red/white from tenergy, one died young and the other is still alive. Spare parts were needed and another device was added that required 9 volts so I got these. an old 9V battery that is still in use today simply no longer has the runtime. I hope one of these 4 will still be working in a decade. daily use. UPDATE 4/2020, 3 out of 4 were scrap, didn't even get used for the first time. took the last one out of the box and charged it, lay on the charger / it said fully charged. Use a timer, don't get 6 minutes on the timer before it's completely dead. Will definitely never buy them again.
- Tenergy protected - Our 9V replacement battery pack is backed by a 90-day warranty and lifetime support from our friendly and knowledgeable customer service team. They also have European RoHS (Restriction of Hazardous Substances) certifications.
