Dell's notebook batteries...
While toying with the Dell notebook config site (I'm getting a notebook soon), I noticed that their 6-cell batteries are advertised provide over 4 hours of working battery life, supposedly because of a different battery technology.
While this is understandable, is this a solid claim? Is it worth the extra cash to get the 6-cell battery? |

Do you mean 9-cell?
The 9-cells are rated at a higher watt-hour rating because they have more "capacity" so to speak than the standard 6-cells. It's like having a flashlight with two batteries or one with three -- the three-battery one will have more power. It's not quite that simple, of course, but that's the gerneral idea.

There is always a trade off between battery life and lugging that big heavy battery around. It will add around a pound to the weight.

No, I'm talking about Dell's 6-cell batteries. Companies like Acer also come standard with 6-cells but are rated to only work 1.5 hours.

Weight isn't a concern to me, but what I was referring to about different battery technoligies was the difference between NiMH and LiON batteries. According to Dell, they use the latter which is a better technology... but how truthful are their claims as to actual working capacity? Last edited by RazorDX; 07-19-2006 at 09:12 AM. |

Everyone use Li-ion for notebook batteries these days. I would be very surprised if any manufacturer was still using nickel metal hydrive (NiMH) batteries (I actually have an Old Pentium MMX notebook that has a NiMH battery yet). I've got a 9 cell Li-ion on my Dual core Lenovo T60 and it probably lasts 3 to 4 hours. HTH

Excellent, thank you. I'll be having almost 11 hours of class each day so battery life is key to my laptop's success.

Lithium is also a lighter metal, lightest of them all, while it's a miniscule difference it is superior to NiMH

If you need that much battery life, you need multiple batteries and a charger.
