EBL 9V Rechargeable Batteries NiMH Everyday 280mAh 9V Battery for Smoke Alarm Detector, 4-PacksClimatePartner certified

The EBL 9 Volt rechargeable battery is slightly smaller than my Rayovac and Radio Shack 9V rechargeables, so it fits better inElectrical Multimeters, Smoke detectors, Stud Finders.EBL 9V has 280 mAhr, which is better than 200mAhr in rayovac, and 150mAhr in RadioShack.I place scotch magic tape over the leads when storing after hearing about a 9V fire on 7/9/2025 in the news.9V batteries are very easy to short if thrown in drawers with paperclips!Great Battery, Thank You EBL- C

I have been using this brand of 9v battery a few years now. I ordered more because I added a few new 9v devices. The older ones still recharge and operate nicely.

Work great. Helps save money on batteries.

11/27 updated from 1 star to 4 for customer service. EBL issued me a refund on the 9V batteries. I really wanted these to work on our smoke detectors, hopefully they can come up with something that handles the constant drain better.We love EBL batteries and have saved hundreds by being able to recharge them for frequently used toys and remotes. But this ain't it for 9V and smoke detectors. I bought them in September and 2 months later the batteries are already drained and 2 detectors are chirping low battery. A normal 9V lasts a year. I could have been ok charging and replacing these every 6-8 months, but not replacing 6 units every 2 months.

Excelente calidad, las pilas han funcionado muy bien

Excellent

The EBL 9V Rechargeable Batteries are a fantastic choice for powering your smoke alarms and other devices. With 280mAh capacity, these NiMH batteries ensure long-lasting performance. I love that they are rechargeable, making them both eco-friendly and cost-effective. The 4-pack offers great value, keeping you well-stocked for multiple devices. These batteries are dependable, providing peace of mind knowing your smoke detectors will always be ready. You'll appreciate the convenience and sustainability of these rechargeable batteries!

The measured capacity of these NiMH 9 volt rechargeable batteries is 180 mA-Hr. I bought a 4-pack and they arrived promptly with no damage. I ran each through several charge-discharge cycles before evaluating the capacity. I also measured the equivalent series resistance, which is less than one ohm, and the self discharge current, which is small. The 4 samples I evaluated are high quality batteries suitabe for long standby applications but are not 280 mA-Hr capacity. They are suitable for many 9 volt powered devices but may have to be recharged more frequently than you expect.
