Up to 65% more capacity
"Newer Technology's iPod batteries are almost perfect, no-brainer replacements for Apple's own internal components: for a considerably lower price than Apple's replacement battery service, the new batteries offer markedly extended run time with virtually no prospect that an installer will damage the iPod's exterior. These factors alone qualify them as highly recommended products from iLounge's perspective."
"It was easy to install and delivered 22 hours of continuous play -- more than double the play time of the original battery."
"Overall, the Newer Ultra High Capacity 2100mAh battery is the most cost-effective way of getting more out of a first or second generation iPod. If it were $50 it would be a bargain: at less than $40, it's excellent value for money."
"For 40 bucks you can buy some fairly sexy items for your iPod -- a cool case, hip headphones, or a sleek stand -- but I've yet to find a $40 accessory that adds as much value to a first- or second generation iPod as Newer Technology's high-capacity iPod Replacement Battery."
"I'd basically given up on using my iPod 5GB before the swap due to the old/original battery - although it ran 4hrs on the continuous play test, in typical use it seemed shorter and within a few days of no use, the battery was dead usually. Frustrating. Now it's like having a new iPod again (only better, with amazing runtime)."
"I hit play at MIDNIGHT on Friday, and let the iPod continuously run. No track skips, no backlight, no volume adjustments. After 309 songs, the iPod finally gave the battery warning and shut down at 11:35 PM Saturday night. That's right....23 HOURS AND 35 MINUTES later, the iPod ran out of power! Instead of buying a new iPod, this is the best $39 I ever spent! Or, if I decide to sell it on eBay, this will stand out above the rest!"
