Hi everyone, welcome to HowFixit.
In this video guide, I'll show you how to replace the battery in Apple Watch Series
1
To disassemble Apple Watch 1, you'll need the following tools:
Tweezers Plastic tools
Glue - I will use B7000 glue due to its high elasticity, anti-vibration, and water resistance
properties.
Screen Disassembly Tool - This tool has a very thin curved metal blade for opening electronic
devices with a screen that is difficult to pry with a common plastic tool.
I think this is a must-have tool for disassembling an Apple Watch all series because the gap
between the screen and the watch body is so thin.
I left links where to buy all the necessary tools in the description.
Before you start, turn off the Apple Watch Series 1.
Insert the edge of the curved blade into the thin gap between the display and the watch
case.
From this position, gradually begin to separate the display.
For a more successful opening of the watch case, warm up the surface of the display with
a regular hair dryer.
To avoid damaging internal components, try not to push the blade deep inside
the watch.
The
Apple Watch Series 1 battery is glued to the watch body.
Use a plastic tool to pry out the battery.
Disconnect the battery cable.
Now you can
remove and replace the battery.
The replacement battery part number A1578.
In the description, I left a link where to buy the battery for Apple Watch Series 1.
Let's start reassembling the Apple Watch Series 1.
Use double-sided adhesive tape to re-glued the battery to the watch body.
Before gluing the display to the main housing, test the battery.
Possible battery issues: when you install a new battery and turn on the Apple Watch
Series 1, the apple logo appears for a few seconds and then disappears again, and so
the cycle repeats.
How to fix battery issues: Fully discharge the battery, then charge the battery to the
maximum and try again.
If the battery issue is not resolved, repeat the procedure.
Let's move on to gluing the display with the housing, this will restore protection from
water and dust.
You can use a special adhesive sticker for your Apple Watch Series 1 or silicone glue.
In my opinion, for protection against water and dust, glue is more effective.
The B7000 glue dries completely after 24 hours, but the minimum surface drying time is 6 minutes.
So, I recommend waiting at least 45 minutes, after which you can remove excess glue.
To fix the display and the main housing, you can use clips or rubber bands.
This repair is complete, you were on HowFixit, and see you next time!
