Best Buy offers extra battery with PSP purchase
It's not too much of a deal ... especially because you have to buy a new PSP system. However, Best Buy is now smartly offering an extra 2200mAh battery with the purchase of a new PSP console. The 2200mAh battery contains about 20% more life than the standard battery, which will allow you to squeeze in some more playtime out of your system. With games going to utilize 333MHz soon, an extended life battery doesn't sound like too bad an idea ...[Via CAG]
Third party batteries suck
Don't be tempted by third-party batteries: they may promise longer battery life, but Ruriweb has proved that they're unreliable, and dangerous too. For comparison purposes, note that PSP is packaged with a 1800mAh battery. Sony offers a longer-life 2200mAh version as well.Ruriweb tested three third-party batteries and they all had incredibly disappointing results. The 2200mAh battery produced only 2000mAh of power. Two other 2600mAh batteries produced only 1500mAh of power: that's less than the battery that comes with your system! To make things even worse, one of the batteries actually caused massive damage to the system (pictured right). The official Sony battery may be pricey, but (ironically) it's the best battery solution by far.[Via PSP-Vault]
