765t Battery replacement

I have been having a discussion related to battery life and thought that its worth asking the question to all.
My unit does not hold a particularly long charge and I think that a new battery is needed, the mechanics of the replacement is not an issue but getting the right battery is!
No one seems to stock the correct battery which is a 361-00019-16 this is a 3.7v 1.25Ah Li-ion, having researched and spent lots of time studying the issue I cannot see any reason for not replacing the battery with a different model ie a 1.5Ah such as a 361-00019-02 or similar, there are also 1.25Ah avaliable, some of these are Li-Pl but this is just different battery technology and should not be an issue. The 1.5 should give a longerbattery life.
Or am I missing the blindingley obvious???
Over to you please

As far as I am aware, Li-ion and Li-Poly require different types of charging, so I would stick to the Li-ion type.

Are you sure that the 1.5Ah battery is the correct physical size, will it fit into the casing Laughing

Hello.

I checked 'on the fly' & immediately came up with this:

The correct voltage/ampere battery replacement

Not original brand of course & it's made in HK, but at least it's cheap Wink

Hi and thanks, not sure if there is a difference in charging but didnt think so, the poly is a diifferent type of construction but is still basically a Li-ion, but I might be wrong, regarding size the 760 unit and the 765 are the same therefore in theory should be the same, am working with "Batterymill" to try and sort the problem.

The site with the list of units again does not mention the 765 as a unit and it is an update of the 760 so who knows, it does look the same but cant see the part number which should be 361-00019-16 or 11 how much is it in GBP?
regards Derek

Hi Telev, Unfortunately the site that you recomended said that they will only deliver in Sweden! but never mind, I have a resolution from "Battery Mill" who are quite confident that a 760 battery will fit so I have ordered one, if it doesnt they will refund the dough, cant say fairer than that.
Incidentally the type of battery construction is not an issue.

Will advise the outcome

Couple of things.

What battery life are you getting ?

Why are you do you feel you have to replace battery ?

Units are less than a year old & come with a 2 year warranty, if there is a problem garmin should be doing this FOC.

Hi all Yes the unit is under two years old but its a second hand job and Garmin charge a fortune to do anything, they wont sell a battery to an individual.
The battery lasts between 2 and 3 hours if I just let it sit on the side, in use just less than 2. It looses a bar almost instantly it is taken off the charger, it matters not if its charged via PC, mains adapter or car, so the battery is definately not performing as it should have tried all the tips ie bluetooth off, lock the screen to operate backlight control, reduced brightness etc.
Batterymill have been excellent but even they could not locate the replacement part number so they are sending me a 760 type and will see if its ok, if not they will refund and if it is then they have learnt something as well.
The 760t does seem to be a good unit and with the current updates I have had no probs whatsoever, I did have a prob with bluetooth not showing the phonebook on my phone but even thats sorted with the latest "mandatory" update. I had read horror stories of this until but bought it at a good price and tried it with some trepidation but it appears that I bought a good un!!

5 was having problems with low charge on my unit last week, unfortunately I was away so did not take the cradle with me & I found out that the USB lead I took with me put gps into data mode !!.

However I found out if you plugged in route without usb lead in place then powered it via lead, though it was still in data mode, you could here voice instructions. (just as well), The screen was showing enter password all the time but then when you entered it it went into pc mode, then back to password again.

I have now ordered a lead the does not put into data mode :-)

Btw , what is the difference on a data mode power lead & not ?

On the battery i found this http://www.batteryship.com/htmlos/htmlos.cgi/batteryship/catalog.html?item=361-00019-11

they ship all over the world.

Well the battery arrived and apart from the battery technology, is identical, ie same size, capacity, voltage and connector, the technology is Li-polymer rather than Li-Ion but this should not make any difference whatsoever, the battery is fitted and I didnt switch the unit straight on but connected to the live updater which stated that it has the latest software, and none of the bits that I have loaded ie POIs etc have been lost so it could have just been switched on it would appear.

The unit is now on charge and I will leave it overnight and test tomorrow, fingers crossed that all will be well!

to save you reading back the battery is a 760 type and my unit is a 765t, the battery is supplied by batterymill who have been great.
