How to replace your M-Audio Microtrack Recorder battery yourself.

It will happen sooner or later, your battery in your M-Audio Microtrack 24/96 recorder will go bad. You have a few options. You could buy some other recorder, return it to M-Audio and have them replace the battery for around $150 or more, or you can replace it yourself for under $10. This article will tell you how to replace the battery yourself. If you are careful, are fairly skilled, and can solder, you should be able to replace the battery.

If your M-Audio Microtrack is dead and it won't power up, first try to recharge the unit for a few hours to see if the display will power up. If that doesn't work, press the power and delete key at the same time for a few seconds to reset and reboot the firmware. Ideally, you should open the case and check the battery and make sure the charging circuit works before you buy a battery. Read the entire article and read how to check the battery before you buy a battery.

Ready to replace that battery? Here is what you will need: a small flat bladed screwdriver and or some plastic case openers, a small philips screwdriver, a soldering iron and solder, a replacement battery (see below), and two inches of double stick tape or some adhesive RTV.

The battery from M-Audio Microtrack is a 3.7Volt, 1200mAhr, prismatic, Lithium battery. The size is: 60mm x 51mm x 4.6mm. A very common replacement battery that will fit is a battery from an original iPhone, which is 1400mAhr. Batteries from the iPhone 3G or 4G will not fit. The iPhone 2G battery is available from numerous sources on eBay for around $6.00 including shipping. The battery usually comes with an installation kit of plastic case openers and some star and philips drivers. Other sources of batteries are from RC model cars. Batteries markets change so often, you might have to search for a lithium battery of the correct size to fit.

First, remove the compact flash card. Place the unit on an open surface and use a ground strap or touch a ground source to eliminate any static charge on your body from damaging the electronics inside the Microtrack. Continue to ground yourself while working on the battery replacement

Next, open the back cover. This is the most difficult part. Take your time and take it easy or you can ruin the plastic cover. Place your sharp, small, flat bladed screwdriver at the corner of the case and push in and lever outwards. You may also try the plastic case openers that came with your replacement battery kit. The four corners open outwards. There are three catches along the midsection, where the flash card inserts and the opposite side, that should be levered inwards as your screwdriver is inserted. It will take a little time to gradually open the case. You may have to place additional screwdrivers at the latch points to keep the case from popping back together. You may leave some marks in the case plastic. That is ok, but try not to break the latches or the case may not close back together well. Remove and place the cover on your bench.

Remember to ground yourself or wear a grounding strap before touching the PC Board! Next, carefully lift the old battery from the PC Board. It has double stick tape holding it to the board. Now, remove two small philips screws holding down the PC Board. Put the small screws in a safe place so you don't loose them. Carefully lift the PC Board. It will be retained by the end pieces of the case. You don't need to completely remove the board, but you do need to lift away the end panel where the line out and S/PDIF RCA connectors are located to get to the battery wires. Some people have found it easier to just snip the battery wires off close to the old battery, without removing the board, and splicing in the the new battery.

You can check your battery voltage to see if is dead. Anything around one volt and the thing is dead. Check the voltage at the battery wires while a charger is plugged in. You will want to see around 4 to 5 volts. That will tell you that it is trying to charge and the charging circuit is working.

Now, you will replace the battery, and how you do this may depend on the battery you get. Do not touch the two battery wires together. It will short the battery out and may cause damage. Basically, connect the red wire where the red wire came from and the black wire where the black wire came from. Leave the white wire disconnected, since it is not used in the M-Audio unit, and be sure to tape over it and to the battery so it is electrically isolated. Your wires may be long enough to solder them to the board or, like mine, they may be short, and require splicing with the wires from the old battery. I used heat shrink tubing on my splice or you can use electrical tape or silicon RTV to insulate the wires. Apply some electrical tape or RTV to cover where the battery wires attach to the PC Board. It looks like the positive lead could almost touch ground if left uncovered.

Next, reassemble the end panel and PC Board with the small screws. Route the wires and placement of the battery so that the battery wires are routed around the battery and away from the case closure snaps. Apply a piece of double stick tape or RTV to the back of the battery and attach it to the PC Board. Then snap the back cover back on. Plug that charger or USB cable in and let the unit fully charge. You should immediately see the screen display working once the new battery is installed since the replacement battery is semi-charged.
