Internal memory battery replacement EKP-IV
Iíve been flying my AvMap EKP-IV for about 5 years now. Really like the unit and still think it is a very cost effective GPS. I have mine panel mounted and run it off of the aircraft power exclusively, I donít keep any batteries in the unit.
Lately Iíve noticed if I donít fly often, the GPS loses its configuration information. If I fly every week or so itís OK but if the plane sits a few weeks without flying, the GPS goes stupid and I have to reconfigure it including the NMEA sentences sent to my Dynon unit for AP control. I tried hooking the EKP up to a power supply at home and left it on for a day or so to see if that would charge up the internal battery but it didnít seem to help.
So, has anyone replaced the internal battery on an EKP-IV unit? I havenít opened my unit up yet but thought if someone has already replaced their battery, I could get a part number, order a new one and hopefully replace it myself. I really donít want to send the unit in for service and Iím pretty sure I can replace the battery myself even if itís soldered in.
