Premium X battery replacement

[R129]

Hi

My trusty premium x only lasts 10 mins or so if not plugged in to charge. I am looking to replace the battery. I’d be very grateful for any advice on (i) where to purchase a new battery (lots of options on the internet, not sure which is best !) and also (ii) how to remove the cover to swap the battery over.

Thanks very much.

Hello
A GPS that is switched on must remain permanently connected to the cigarette lighter socket provided with the GPS.

What battery reference? You must disassemble your GPS and check the reference.

 

[R129]

Thanks for the quick reply.

It isn’t clear to me how to disassemble the device. There are no screws that can be seen. Can you advise how to remove the cover so I can get to the battery please ?

 

[Willy875]

Try this video,

normally GPS devices are disassembled in the same way.

 

[R129]

Thanks for this.
My tomtom (premium x) does not have any visible screws on its shell. The video shows the first step to be removing 2 tiny screws. My tomtom does not have any screws that are visible.
If someone could please help with accessing the battery I would be very grateful.

 

[Willy875]

Look under the label if there are no screws, the shell is simply clipped, so take something flat to unclip the 2 parts.

Before disassembling your GPS, recharge your GPS with a phone mains charger for 2 hours, then plug your GPS into the cigarette lighter charger and test.

Thank you.

Yes, you'll find a fair number of sources for GO 5x00, and 6x00 batteries, all of which are fine in the Premium X.
The thing to watch for is that it's a 5 wire connector, and at least 1100mA. Some of the other devices use a 3 wire. Contrary to what they're showing above, the GO 5x0 and 6x0 didn't use this battery. Those use the 3 wire version.

The AHA11111008 is the key number for searching generically.

I like your deal on Amazon better than https://www.subtel.co.uk/Battery-fo...ro-Truck-5250-AHA11111008-VFAD-11-920458.html

Yes it is a better deal, but you still have to be careful where you get it from, look what happened to the battery that went up in flames with the Company my son works for !!!!!!!!

There are several reasons why a battery can explode, but it doesn't necessarily have to be the battery itself.
A faulty charger or leaving a GPS behind a windshield in direct sunlight can cause the battery to swell.

just to add - my Go Premium X did not have any screws - just unclipped (carefully) using plastic tools bought for a few GBP. Once the case was very carefully opened, it was just a matter of temporarily disconnecting two cables (one of the ribbon cables, one a pair of wires), leaving the screen partly connected via a ribbon cable- the battery was readily accessible - no screwdriver required. It took longer to unclip the case than to do the rest.
It's handy to have some double sided sticky tape to hand to adhere the new battery in place.

It was just a nightmare to open the case of my premium X for a battery change ! Even with the appropriate tools. Now for me it's clear TomTom never again. Sorry but that's life. Poor quality makes a company to diseapper quickly.

As I understand it, the standard 2.1A USB port in cars is *never* poweful enough to fully charge the battery in an TomTom sat nav I've had, no matter how long it is left plugged in to the car or how new or old the battery is.

The concepts in the - aged - manual that these are portable devices which can be used on foot on the battery are, IMO, not remotely practical.

In my experience, the only way to get the maximum charge that the battery will take is on a USB mains charger - even then, they don't seem to like any sort of fast charging. Probably old styie charging circuitry.

As to 'no more TomTom' I suspect TomTom will

I replaced the battery on an old model - now long disposed of... - the charge retention was no better than the old battery!

One option *might* be to plug it in to a USB Powerbank - say 5000mAh or higher - rather than rely on the car power.

This is probably a case of 'flogging the provbial dead horse', IMO.

These are devices designed to sit behind a windscreen for hours at a time. They should, IMO, have been designed for such conditions

Having done a couple of in-vehicle electronics product designs, I can assure you that the dashboard/windscreen area of any vehicle is a HORRIBLE environment for a device with a battery. Apart from the N and S poles, there's nowhere that isn't going to produce dash temperatures that exceed the storage specifications of any lithium ion battery manufacturer, much less the charging specifications!

Companies like TomTom do what they can by preventing charging when the battery temperature renders it unsafe to charge. That's about all they can do.

A car charger is included with the GPS. Its purpose is to keep the battery charged, but it will not recharge the battery.

There can't be many electronic devices that can withstand the heat behind a windshield.

TomTom or Garmin could have designed a heat-resistant GPS, but in my opinion, the price wouldn't have been the same.

Another solution is to mount the GPS near the air vents.

 

[John Usher]

Them how that is communicated clearly - or not - to the device user through the device user interface is also an issue.

Also, devices are priced to sell

Another solution is to mount the GPS near the air vents.hich, based upon bitter experience, and a desire to keep sight lines clear, is precisely where my TomTom now sits!!@ But no doubt someone will comment that we shoudn't use the air-con as it will overcool the device...

'...to keep the battery charged, but not recharge it...'

In my view, that's a Power Supply Unit (PSU) not a 'charger', which is misleading!

The problem with all this is that such things are learned by the owners by mental osmosis, and not - as far as I know - by TomTom documentation, owned by them freely available to the device owners. THAT, IMO is the real problem.

When I say cigarette lighter charger, I'm referring to this accessory.
