 Posted: Mon Nov 20, 2006 8:46 pm Post subject: Mio 510 battery problems |
 |
|
Hello folks!
I've had my 510 for quite a while now - maybe 6 months or a little more and I've noticed that the battery life is no more than an hour now (in smart screen mode). It used to last for 2.5 to 3 hrs!!
I've also noticed that no matter how long I charge it, the battery never goes over 75%.
I've discharged the battery completely and charged it for hours and hours many times but I just can't get it to 100% or get more than an hour from it.
Is it time to get the wonderful Mio support involved (oh god, please noooooo!) or is there anything else I can do?
Any ideas anyone?
Ravi

You have described the classic symptoms of a worn-out battery.
It might be worth contacting Mio as they do seem to be quite good at resolving hardware failures - it's the software bugs that they won't acknowledge. Having said that, batteries are normally considered a consumable item and excluded from guarantees. You may have the doubtful privilege of being the first user to find out where to buy and how to fit a replacement battery - please let us know how you get on as we will all have to do the same eventually.
Good luck!

Hi ravi.
Long time no hear.
I do hope it's not anything like a Navman, the poxy battery is soldered in and the only way to change the battery was to send it back to the manufacturers, so they said.
Haven't had my Mio apart yet so I don't know.
I seem to recall I got mine a couple of weeks after you but my battery is still charging to 100% and it's been used every day.
Is this a sign of things to come?
I know it will eventually come as it does with all rechargeable batteries, but I'd have thought you would have got more than 6 months out of it. Most rechargeables are good for 1000 charges these days. I make that over 3 years if you charged it every day.
Good luck in getting it sorted.
CeeJay. |

Hey CeeJay,
Pressure of work has kept me away but it's nice to hear from you!
I just checked the purchase date this morning and I've actually had the thing for 4 and a half months! In total, I've used it maybe once a week or so after the initial unnecessary usage that every one goes through for the first couple of weeks.
I got the Mio from Super E Trader so I'm fully expecting the old "you have to send it back to the manufacturers" run-around from them so I'll post the details a little later for all to see.
Still, I'd say that 4.5 months is a bit crappy for battery life but well within the expectation of failure that I have for a device from Mitac!!

Mine is 5 months old and is definitely not holding the charge as long as it did when new. I suspect that what kills the battery is not cycling it but a constant overcharge when it's plugged in to the car. I often unplug it on a long journey to let it cool down.
There are several battery specialists so it's probably worth a Google and a quick phone call.

Hi Sal
I always use it on battery in the car as I really hate the cable trailing about the place. I've always charged it at home, run it for as long as possible (until it runs out) in the car and then charged it again at home until it's at 100%. Surely this is the best way to use the battery?

You are correct if it is a NiCad (Nickel Cadmium) battery. Not sure what type of battery is in the Mio, haven't seen my manual for ages.
If it's a LiOn (Lithium Ion) battery then it doesn't matter when you charge it as they do not suffer from the dreaded 'memory effect'.

Absolutely true, but neither type likes to be continuously overcharged. My point is that judging from the heat generated in the box it is likely that the current through the battery is excessive once it's fully charged.

That could well be the case. So I'll shut up now. 
But, like yourself Sal, I charge mine up fully, then run it right down. It is certainly the best way to use a rechargeable battery of any kind.
Seems to work for me.

| Can understand the comments on using it on battery until discharged, but this does not help when you are using the TMC. The receiving adaptor needs to be pluged in to function as i understand it, or have i got this wrong? |

Not with the 710, which has the TMC receiver built-in.

Sorry, got a bit blinkered towards the C510 there. |
