Posted: Sun Apr 19, 2009 9:00 am Post subject: A10 battery drain on new software |
|
|
I have been using rechargeable AA batteries for some time (currently using Duracell 2650mah NiMH). But since the latest software upgrade I thought I had noticed that they were starting to drain more rapidly when the machine was off.
With the previous version I had charged them and left them in the switched off machine ready for the next walk. But this has caught me out with the latest software and a surprise change of batteries was necessary on one occasion.
As a test I charge up four cells a few days ago, put three in a switched off A10 and one on the window ledge the % drop in voltage from day one was
Batteries in the A10 10%, 13%, 22%
Battery out of A10 3%, 5%, 6%
On the fourth day I switched on the A10, got one red bar, was told the the battery was critical and it then shut off before I could do so!
I know this is not a very scientific study but it does warn me not to store the batteries in the unit.
Has anyone else had a similar problem? If so do you think it is the latest software upgrade? _________________ LostMike

I run RS Componants 2600mAh Ni-Mh AA's in mine After a full recharge I reinstalled them and left it on the shelf for the last two weeks. It is still reading 3 bars.
Version 1.3.2.3
Maybe its your batteries... |

In which case why did the one on the shelf not lose any where near as much?
P.S. Thanks for the response and delighted to hear that your's retain their charge. I would be interested in anyone else's experience on this. _________________ LostMike

How long roughly?
I had a set of 3 year old rechargables (UniRoss 2700 mAh Ni-MH) which had been used in my StreetPilot i3 almost every day for 2 years. Last year they were moved to my camera where i could leave them in for weeks and they'd be fine. However a few weeks ago they refused to hold a charge over night. Fully charged batteries would be fine after charging but left in a switched off camera they would be almost dead the next day - the warning light would come on after 2-3 shots and then camera would fail to retract. Eventually the only solution was a new set of batteries which cured the problem.
In fact, I've just checked, and the camera is still working off the new batteries and they were last charged 3 weeks ago....
I used a set of a set of hi powered "normal" batteries to test - a £4 set of Energiser Alkaline 4 x AAs - and even after having taken over 100 shots and having been sat in the camera for 10 days they still had a good charge in them, so i got the new rechargables.
If "normal" batteries go flat in the same time as your current batteries there must be a fault in the device, other it probably looks like time for new batteries. |

Perhaps the Active10 is 'waking up' from time to time to do some housekeeping etc? Quite common with PDAs. _________________ Phil |

Charged up my Satmap battery about six weeks ago and it was sitting in a drawer since then. Took it out today and after a two hour walk it is still showing four bars, so I don't think there can be any significant draw on the batteries when turned off. |

Thanks for that Davidor.
Can you just confirm that this is with the latest A10 software (1.323 ) and the Satmap battery pack?
Though I am using rechargeable AAs I assume that should not make a difference. I have now tried new rechargeables and they still seem to lose power when switched off! Ho hum.... _________________ LostMike

Hi Mike
Yes it is the standard Satmap battery that has been through many charge cycles now and V 1.300 software. I didn't think anything significant has happened to the software since then as I haven't been advised by email from Satmap to upgrade.
I was out of the country for 4 weeks (left just before the new world-wide base map!), so gave it a good charge before I went as I was a bit concerned about stories of battereis running down and flattening batteries never does them any favours. I checked the battery when I got back a couple of weeks ago and it was still showing four bars but it wasn't until today that I got out to use it.
Has V1.323 changed the power setup? |

That is the question. I don't recall my batteries losing any significant power under 1.3 but they seem to since I upgraded. _________________ LostMike

I've upgraded now so it should be fairly plain if there is a difference. I will report back.
I didn't realise until this thread that there was another upgrade, so hadn't put it on. I recall reading something about another version after 1.300, but thought that was just language upgrades; clearly there is a little more to it from the upgrade notes.
Obviously I will have to wait a week or so to see if I do now start getting battery drain whilest switched off. |

Thanks Davidor.
Seems fairly clear. The problem is mine. It does not seem to be the batteries which are fine outside the A10 and otherwise I can't see anything wrong with the A10 so I'm not inclined to send it in for a service yet. We, or rather I, shall see.
Thanks again for the help. _________________ LostMike

Mike: Used it again on Sunday for about 4 hours with a fair amount of screen viewing without recharging itfrom last week. It has just dropped to 3 bars. I'll leave it for a while without charging it to see if it drops any more.

Another week has gone by. Still showing three bars and also after two hours use still had three bars. I have to conclude that ther is no discernable battery drain while switched off, as after two weeks and about 9 hours use it is still showing three bars. |
