Laptops With Sealed-in Batteries
- But thereâ€™s a dirty little secret about removable-battery laptops owned by average consumers: Hardly anybody buys extra batteries. Research firm NPD estimates that fewer than 5% of consumers buy a spare. So, a small trend has begun in the industry: More electronic products are being designed with their rechargeable batteries sealed inside. For instance, Dellâ€™s new high-end laptop, the Adamo, has a sealed battery, as does the excellent Flip pocket video camera.........Apple says this makes sense because sealing in the batteries lets the company make them larger, without adding heft to the laptops. Apple says the two models are the same size and weight as their predecessors, yet their battery capacity has grown by 33% and 46%, respectively.
