Any ETA on the E7440 battery?

I have 2 E7440’s I got dirt cheap, but neither included a battery. However, I did find one in the junk laptop I bought for the FHD Touch panel which I tried to make work was sold with one that held a charge, so I figured I was set on the battery problem. However, it has always had an issue with unusual expansion and I did confirm it has a possible cell issue - whatever, it’s a 389+ cycle pack. It had 83% health, so it wasn’t like so many of these with low health where it’s a unnecessary risk!

However, while I was able to get the top to make it look okay I need to get another one since the OEM flat packs are somewhat known for this exact issue with high cycles and misuse (however, a properly cared for high cycle will probably be fine) and mine was affected. In addition, I’ll eventually need it for the other one because I need to update the BIOS at some point to remove the asset tag.

Is there an ETA when the E7440 battery will be in stock again?

Hey Nick!

Good question—let me check on this for you.


@kristen Sadly I suspect it may be a while due to Covid remote learning. I'm not shocked since the old OEM flat cell packs are often plagued with this issue, especially with years of deep discharging - I had a feeling once it felt off. Never see this on the E6 18650 pack - they just run like crap and never properly calibrate once it's bad enough or go into the 30-39% health range, which is the magic number that tells you it's time. I held out since it had ~83% health but only ran for 2-3 hours max, which is not a good sign.

Part of the problem is I'm probably going to be last to get them because I bought mine as a gamble seeing as the version I have is worth $250 working - and I got 2 as a lot super cheap. Everyone else is buying up the 768p i5-4300U SKU for remote learning, but my i7 Touch machines (WiGig ready!) got passed over due to a boot problem. Few come with batteries since they're a potential problem, especially high cycle.

Mine was fine, until I charged it once. It happened after one charge, and it got worse.

Hi Nick!

This part is estimated to be restocked in about two weeks, but there is a possibility of delay.

Yeah that's what I was afraid of. Especially right now.

But even if that used pack worked out to get me by, I'd probably need new at some point since the CPU I got with mine isn't exactly a power sipper (i7-4600U).
