These Batteries are good for 1.2Volt Appliances that require only 1.2 Volts Batteries. If you use in appliances requiring 1.5 Volts batteries, then they drain out faster.Even though it was my mistake and focused only on 2800 mAh and did not pay attention to 1.2 Volts ( I wish they advertise that prominently), the Vendor sent me more than a dozen Li-Ion Batteries (higher quality and more expensive) with Chargers to give 100% satisfaction to me. It was more than Fair.Very Fair Vendor
