As we reported last July 31st, if your MacBook Pro batteries (a) have A1175 as their model number, and (b) their serial numbers end with U7SA,U7SB, or U7SC, you still might want to replace your battery, just in case.

For all other MacBook Pro battery owners, you can breathe a sigh of relief.

The US Consumer Product Safety Commission (CPSC) reviewed the substandard batteries used in early MacBook Pros sold between February and May, but found that they didn't pose any safety threat.

The battery exchange program came about after MacBook Pro owners complained of a "high-pitched buzzing sound" in their notebooks, and problems concerning recharging. However, Apple maintains that the recall of the MacBook Pro batteries stemmed not from any potential fire hazard such as that which plagued batteries in Dell laptops (or for that matter the batteries in Apple's iBook and Powerbook G4 models which were recently recalled), but because those batteries failed to meet the company's high standards for performance.

So except for those batteries - where the damage is really obvious - and those covered by the replacement program, as far as the CPSC is concerned, MacBook Pro owners can relax. Still, it doesn't hurt to be a little vigilant with your MacBook's battery. In light of the Dell exploding laptop and concerns with laptop batteries, it's better to be safe than looking at a damaged notebook from any manufacturer.
