[quote=“allperils”]The batteries in Taiwan are the same batteries they use in Canada. They’re both made in China.
Your vehicle is losing it’s charge and it’s not a normal occurance.
Get a multimeter to check the charge of the battery. It could be the sparkplugs, or ignition coils/wires. Batteries do not lose their charge in 4 days, especially Taiwan’s mild climate.[/quote]
And I have never, ever heard of a battery drain due to its spark plugs or ignition coils and wires. nine times out of ten its the alarm system or stereo. Eight times out of ten its a door lock motor. One time out of ten its something else.
Pull the positive terminal off the battery and connect your multimeter between positive battery and positive wire. The multimeter at this point should be set up to be showing Amps, and this commonly requires that the leads on the multimeter be switched around. Use the 20A setting. Oh, and remember to have the vehicle switched off, all door lights off, and in the case you have a bonnet/hood switch, then depress the switch, or use a screwdriver to close the locking clasp and mechanism which holds the bonnet shut. You need the bonnet open to read your multimeter, but you don’t want any closed switches potentially setting off any computer systems.
With the multimeter connected, you should be getting a typical normal reading of around 0.03 amps. In this case you have no parasitic draw. Just to make sure you have set up properly, you can experiment by turning on the interior light to see if your meter readout changes. If nothing changes, or your screen is reading zero when your car has an electronic control unit, then you likely haven’t set up your meter properly.
If you have a reading over 0.05, then this is considered high (unless working on Fords) and you should investigate your vehicle’s systems to figure out where additional the drain is.
If you have a higher reading over 0.03 at the beginning of the test, then having checked all lights, stereo and auxiliaries are off, wait for up to twenty minutes with multimeter hooked up, and then re-check the multimeter screen. A few (very few, and mostly non Japanese) vehicles will show a high drain for up to half an hour as the vehicle’s ECU has taken longer to go into “sleep mode”. After the half hour point, then almost all vehicles should be reading around 0.03.
If reading over 0.03 after all is done, then you should begin disconnecting any alarm system first, starting with its siren, as that is often built with a backup battery which typically fails after around four to five years. Next disconnect any stereo system, and especially any amplifiers which may be permanently wired to the battery. In some cases vehicles may be fitted with additional T.V. boxes, GPS tracking units and other systems which sometimes require a backup battery. Any system which incorporates a backup battery will often fail and result in a direct parasitic draw from the vehicle’s main battery. These types of systems should always be investigated before any other as they are almost always the greatest common cause of significant battery drain.
If your vehicle’s systems are only drawing around 0.03 amps, and you are still loosing significant battery power over a relatively short time of around a few days, then the fault is most likely your vehicle’s battery or charging system.
First, in the event of a battery drain, check any system which has a battery backup, i.e. alarm, GPS Tracker
