Typical !!
As soon as I said I was happy with the SatMap it starts to have a problem.
After charging the Li-Pol battery it has started not wanting to switch on.When it first occurred I thought it may be "one of those things" but it has done it four or five times now.Can rectify it by disconnecting/reconnecting the battery but of course that is only a stop-gap.
Have e-mailed SatMap so i shall see what they suggest.

Hi Bosun
Have to tried flattening the battery completely before charging it? As the unit / battery will have a "memory" of the charge state.
Flattening it completely then fully charging it, will allow the unit / battery to become sychronised again.
Hopefully it might help
Thanks

Mark,
Thanks for your suggestion but I have flattened the battery a few times and recharged ( not particularly for this problem but I read somewhere that it needs five good full charges before it reaches its full potential ) and it hasn't made a lot of difference.
I am leaving it as "won't turn on" till I see what SatMap say as if it is working when/if I return it they won't be able to observe it.

Do you have 1.20 installed? I had something similar and it turned out to be a 'freeze' issue not the battery per se. |

DO NOT FLATTEN LiPol BATTERIES COMPLETELY. They will suffer degredation and not take or hold the full charge in future. Memory issues are not supposed to be a problem with LiPol batteries. The unit should be designed to disconnect before the battery voltage drops to the danger level.

Yes I have always had 1.20 installed.
jonesbach,thanks for the info about Li-Pol batteries.By flattening them I mearly meant until the unit switches off.

I have had exactly the same issue....had 8 months of regular re-charging with no problems...then started to get the problem mentioned in the Bosun's post, where the unit will not switch on after charging. It does not happen every time but often enough to be inconvenient...unplugging the battery sorts it out.
I'd be interested to hear the response from SatMap |

Charged it up night before last and it wouldn't switch on yesterday morning or evening.This morning it switched on but it said battery was low and switched off again.So it had never charged in the first place or it had discharged in 24 hours or so.
As I hadn't had a reply to my e-mail so far I telephoned SatMap this morning and they told me to return it to them to be repaired/replaced.
Incidenatally,if returning stuff to SatMap don't forget to ask for the Freepost address to save laying out on postage.

I see there are a number of people who suggest unplugging the battery
My Satmap went totally dead after many months of faultless use . Tried everything including replacing the Li pol withh AA batteries.Sent it back to Satmap and got it back 3 days later ! The Repair report reads "Board repaired - Power connector pins were badly bent "
I was not concious of forcing the pins but the connector is very delicate and not suitable for even occassional use never mind the great outdoors
As the Satmap is a computer it needs a robust way of disconnecting / swopping batteries |

Well got the SatMap back today and they have replaced the Li-Pol battery so we shall see how it goes.Hopefully all will now be OK.
Excellent turnaround time,especially as it is so near Christmas and no paying out postage and claiming it back etc.
I must agree with Michael,the battery connection seems awfully fragile and fiddly especially if there is a need to disconnect/reconnect whilst on a walk.I hope this can be rectified sometime in the future although I don't really see how for those who already own units but you never know.
