Lihium battery packs can last years . They store lots of power when new If you leave the battery discharged for a few months then one of the cells inside the pack will not take a charge anymore. The battery packs are sealed up tight in plastic so buying a new pack is easier the trying to smash open the pack to replace a bad cell. That is the way it goes today, batteries made of recycled materials cannot be expected to last very long before they get recycled again.

I replaced a 5 year old battery with this. My laptop went form having 1 hour to 3 hours of battery life. It takes a long time to charge though, maybe it's just because it holds more so it takes longer.

This is a good replacement battery for my Dell Inspiron 15. Before buying it, I compared the specs with the original battery and made sure they matched. Now it is doing well, and has brought new life to my laptop.

The only reason I didn't give it 5 stars is that I've only had it a short while. Battery charged fully and the laptop was used for an hour and worked fine on battery.

Time will tell. So far, so good. Great value over OEM.
