E4310 battery work on E4300?

I've had very variable performance with Li-ion batteries over the years. I took out the extended battery warranty for my E6400 and, so far (21 months), haven't needed to use it. However, although it frequently partially depleted, I have only run it to near empty on a few occasions.

I run around from meeting to meeting all day, running on battery power. any chance I get to be at my desk, I plug it in for a quick charge (express charge enabled). so many times throughout the day it gets a quick 5 to 15 minute charge. which with express charge is usually good enough to add a good 30% charge back to the battery.


Been doing this for 10+ years, and every battery I've had always die within 6 to 9 months.

Not limited to Dell, as I've had IBM/Lenovo/HP/Compaq/Asus laptops that all have had the same issue.

 

That's a lot of charge cycles and I suspect that the express charge doesn't help. The higher charge rate causes extra heat which isn't good for the battery's health. It would be interesting to see if the 3 year battery can cope better with this lifestyle.

From Dell rep - the E4310 battery can be used on the E4300, but the E4300 battery cannot be used on the E4310. The 4310 bios will identify batteries that do not support rapid charging - so it will tell you if a battery is not supported.

 

Interesting choice by Dell. I'm glad that even with the new form factor, the batteries are backwards compatible.

 

They go to great lengths to tell us that the E series is a platform that will be stable for 5 years.

My personal guess is that the e4300 battery will actually work with the e4310, but will not support rapid charging. That is my personal guess, and guesses are bad.

 

but the E4300 battery supports rapid charging on the E4300, so why wouldn't it support it on the E4310? strange.

It's good to know that the new 3 year battery will work on the E4300. I'm going to pick one up when they become more readily available, or when this new replacement battery starts to act up.

 

Sorry - did not realize that rapid charging was available on the e4300.
