Determining Battery Health

There are several methods of determining your battery’s capacity relative to it’s initial specification (aka “health”).

* Press and hold the status button located on the bottom of your laptop battery. The five LED lights will initially display your battery’s current charge (five lights is charged, zero lights is discharged), and if you continue pressing the status button for three seconds the lights will blink off and back on again, now displaying the health of your battery. If zero lights appear your battery is operating at greater than 80% of its specified capacity, if five lights appear your battery is operating at less than 60% of its specified capacity. This information was pulled from the D620 User Guide.

* If you enter the system BIOS by pressing “F2″ during the Dell logo while booting, there is a “Battery Health” option under the “Sytem” menu which gives a qualitative assessment of battery health.

* The power manager under FC6 tracks the maximum capacity of your dell d620 battery at its last full charge and generates a health percentage based on the factory spec charge for your battery. To view this information, right-click the battery meter in your gnome panel, select “Information”, and expand the “More” area of the “Device Information” panel.

* If you kept your initial Windows XP install, there is a battery health meter under the Dell Quickset applet in the lower right hand corner of the screen that gives the same information that is available through the system BIOS.

Obtaining a Replacement Battery

Of course, you always have the option of purchasing a replacement dell laptop battery from Dell (9-cell or 6-cell), or simply living with degraded battery life. There are some circumstances where you may be able to obtain a replacement under warranty, though. If the BIOS/Quickset health gauges are showing the battery as failed even though it’s less than a year old, Dell will replace it under warranty. According to the phone rep that I spoke to, a battery is considered to have failed when operating at less than 50% of its rated capacity. When I called, my battery was five months old and operating at 50%-60% of it’s capacity (5 death lights, BIOS noted lowered dell d830 battery life but did not pronounce failure, FC6 power manager rated health at 56%, observed battery life was 50%-60% of expected). I was able to successfully make the case that the battery was clearly borderline and would certainly be replaced within a month or two, and that doing so now was an opportunity to provide excellent customer service whereas forcing me to wait would serve no purpose other than irritating me. To his credit, the phone rep immediately acknowledged that my line of thinking was reasonable, spoke to a supervisor, and was able to authorize the early replacement.

Reviews about dell battery

Physically, this item is nearly identical to the Dell branded battery. There are no quality issues at all. It does have the dell latitude d820 battery meter on the bottom, just like the original one. Since my Dell unit crapped out after 18mo, I can’t do any side by side comparisons, but I think the original unit had a bit more capacity. I recall getting 4 hours on my D620 running Fedora Linux (thought that was for maybe the first couple months). This unit is maybe 3-3.5 but again, I haven’t really done any scientific tests. It could be that I’m just harder on the battery now than I was then. Either way, it’s a steal at roughly 1/3 the cost of the Dell unit.

It’s been almost a year of regular use and I still have more than 3 hours of dell latitude d620 battery life! Had 4-5 hours when it arrived and that lasted for several months. Only downside, for some reason, after 25% use it thinks it’s out of juice and it turns my computer off. But, my computer turns right back on without problem. Also, it doesn’t exactly fit flush, but it’s still better than the battery dell sent me with this laptop. GREAT PRODUCT!

Review”I use my laptop on the road all the time. This power supply is a wonderful add on! It works as it is supposed to do and it is solid as a rock. Great Product. After my Dell Latitude D820 adapter broke on my latitude d620, I first bought a universal adapter from a major electronics retailer. Although, the universal adapter would power my notebook, it would not recharge the battery. After doing some research on the internet, I found that many aftermarket adapters will not charge the Dell’s notebook battery. The good news is that this adapter effectively powers the notebook and recharges the battery. It’s a lot cheaper then Dell’s OEM adapter and it has worked fine for me. “
