Honda Accord Tourer - Battery died but has green "telltale" LED - likerocks

Starting my Accord iCDTI has been a bit laborious a couple of times recently. Over the bank holiday weekend it hasn't been driven and now it cranks but will not start.

The original battery is the OE one, so 8 years old. I guess it doesn't owe meanything so I was planning to nip straight out in my wifes car when the shops reopen tomorrow and buy a new one.

BUT I was having a nose around under the bonnet to look at connections, retaining straps etc and saw that the "battery condition" window still shows a green telltale. Should I investigate further before shelling out for a new battery? I have no reason to believe that the original battery hasn't been charging i.e. no battery warning lights.

I have seen some 'Vauxhall' batteries that are dead but still show the green blob in the window so I wouldn't read too much into it.

But you say that your car cranks but does not start???

starter turns but very weakly, dash lights dim. Also, for some time, the headlights dim a lot when I (rarely) turn off the ignition with them still on......all symptoms point to a weak battery but the green blob confused me.

Seems that a cell is faulty, if at first sight the battery seems OK but loses power after a second or so under load. A drop test is required to establish this, which is routinely done by various businesses that supply batteries.

New battery went in today. Started pretty well on the button. Drove 20 miles to work. Left it all day. Amazingly good starting at coming home time. Think the old one must have been weak for a while. One surprise benefit is that the car seems quicker and smoother now the engine management has been reset whilst powered down! All is well!

I didn't take the old one with me for testing as I didn't realise Unipart would offer this service. However, the guy put my brand new battery on the tester and it failed! He then started muttering something about calibration. That's quite a handy sales tool...!
