Rechargeable (USB-C)
Creates a more premium unboxing experience and reduces landfill battery waste, a genuine sustainability marketing angle for consumer-facing products — but adds a charging cable to your packaging and a charge cycle life limit to disclose.
Replaceable (AA/AAA)
Lowers unit cost and simplifies bulk corporate procurement (no charging behavior to manage across a fleet of devices), which is why enterprise-positioned products still frequently default to replaceable batteries despite the consumer trend toward rechargeable.
