I'm looking for a battery that offers longer usage time before needing a recharge. Ideally, it should have low self-discharge rates so I won't have to worry about it losing power quickly when not in use. Could you provide me with some options that meet these criteria? I'm particularly interested in specifications related to performance and longevity. If you have different models available, I'd love to know the details for comparison.
