Hey guys - so the internal rechargeable battery in my dash cam has begun to swell - causing the case to bulge and the device to shut down randomly. (link to product) (It's outside of warranty)

I figure I could easily solder in a new one provided I check with you guys (I only have basic understanding of electronics as it's only a hobby, not my field of expertise).

• Any tips for how to source one? I was just going to look on eBay but am a bit lost with all the options.
• I obviously have to match the power ratings... but is there any flexibility?
• Is there a way to find out if this is a fairly common battery, eg. the serial

Here are the specs (as best I can read them!)

• Battery model no: 059445
• Rated capacity: 800mAh
• Standards voltage: 3.7 V
• Charge limit voltage: 4.2 V
• Executive standard: G?/T1?2?7-2000 (the first ? could be a B or an 8, and the last 2 ? could be 8's or 0's.)
• (unknown number at bottom) 20140515F (is that last digit really an F?)

Here's a photo of the battery, I already clipped it out since it's only going to damage the device if it explodes anyway...

 

It looks like a life-po battery pack like these

Get the measurements for your pack to compare.

At 3.7 volts the battery is a lithium type and so you do need to be cautious in charging and discharging the replacement device. My choice would be to build a regulator circuit and power the dash camera from vehicle power. The actual current is probably around 100Ma, so it would not be a huge regulator. There may be a linear regulator available, that would be the simple way to go. Then no more battery replacement issues.

Do you think about what you say? Do you know about load dumps in a cars wiring circuits? There was a reason the company making the camera didn't do what you suggested. But what the heck, it isn't your camera that could be destroyed.
