These battery's last a long time . I use them in my remote control ,my weighing scales and in my children's toys . I haven't had to change the battery in at least 1 year .

Probably the best rechargeable batteries ive used, quick charging and hardly ever have to recharge they last that long! Excellent value for the price

Very convenient to use in my Xbox controller. I have had these 2 sets (4 total) for just about a year now, and have used them VERY heavily. They still charge right up and I get a total of 4-5 days of moderate to heavy gaming of about 4+hours per day. I have saved SO much money on batteries. They pay for themselves almost immediately.
