I have Nuvi 3590LMT in need of a replacement battery.
Has anyone purchased a replacement battery lately, and if so, what was your source?
I see a "NEWPOWER99.Com", and a few on ebay and Amazon
But what has been your best source?
NewPower99 is certainly a great source and has great YouTube videos. They may be a bit pricier than other sources.
Some folks go to eBay and that's probably a cheaper source for usually great products.
My suggestion is to use who I've bought from in the past, BatteryShip:
https://www.batteryship.com/ and just put in nuvi 3590LMT in the Find box. Interesting, I see two batteries offered with tools and the slightly larger capacity battery is actually a tad cheaper and looks different. Batteryship includes tools and offers free shipping.
If buying from Batteryship, I'd suggest the cheaper 1250mAh battery since it corresponds to what the NewPower99 one looks like and has the same capacity.
Thanks for the info CraigW.
Thanks for the info CraigW.
I do see that the 1250mAh battery for your nuvi is a special order item with a 2-3 week shipping while the 1000mAh battery is in stock today. Unless you're in a big hurry, I'd still suggest ordering the 1250 battery.
If ordering through eBay, be sure to check where the Seller is shipping from. If from China, my experience is shipping times of 4-8 weeks and maybe a 5% loss in transit experience. Also, if you need the tools, make sure your purchase is for battery plus tools.
Got mine from https://www.batteryship.com/ earlier this year for my Nuvi 760. The same CraigW suggested it on this thread: http://www.poi-factory.com/node/46110
The battery comes with tools too and it has worked fine so far.
Don't need a battery at the moment but are the Garmin units easy to open up to replace the internal battery?
With the exception of some of the oldest nuvi devices (e.g., the 3x0 and 6x0 series), it's pretty easy with the right tools. Go to YouTube and search for your model GPS plus battery replacement for a visual guide.
Jgermann has linked several in his FAQ which will give you a good idea on how to change the battery:
Well, I ordered one from where CraigW suggested. I did order the 1250 battery, but realized it was a special order and looking at 3-4 weeks out.
I need a replacement "Now"! So I ordered one from NewPower99 and paid top dollar. But I did need it right away.
I left the other order in place since I have 2 3590's and I am sure the other 3590 will need a battery soon.
I tried charging the 3590 with the bad battery with a wall charger, but when it was completely charged, I looked at the diagnostics screen where it shows the battery "capacity". It started out at 100 and went down rapidly to 4% very shortly after I unplugged the charger form the unit.
Did you set brightness level to 100%? It sounds like you got a bad battery. Mine lasts a long time unplugged but I set mine to screen lock (dimmed).
Thanks for the reply.
The brightness level was set pretty high, either 90 or 100.
I am pretty sure the battery is going bad.
The new battery should arrive in a couple of days and I plan to change it as soon as it gets to me.
I have replaced the battery in my old 760 and it was pretty easy to do. Just go slowly and be patient. If only it was that easy to replace the battery in my phone.
