Panasonic BK-4HCA24/CA pro AAA High-Capacity Ni-MH Pre-Charged Rechargeable Batteries, 24-Battery Pack

I've been using these rechargeable batteries in my Kwikset electric deadbolt locks for a few months now, and I'm thoroughly impressed. They consistently provide reliable power, even during frequent use. Key Benefits: * Long-lasting Charge: These batteries hold their charge exceptionally well, significantly reducing the need for frequent replacements. * Reliable Performance: The batteries deliver consistent power, ensuring smooth operation of my electric lock. If you're looking for rechargeable batteries to power your high-drain devices, I highly recommend these. They're a cost-effective and eco-friendly solution that delivers excellent performance.

I thought the more expensive big brands would be much better, but in reality the battery drains very quickly and the battery capacity is not as much as before

There were at least 6 battery's that were bad,the rest was fine,but it was to late for a full refund...

Every time I need a battery I try to use these and the battery is dead so first I have to charge before use. Ridiculous.
