How do you check battery charge? - Kodak EasyShare C913 Digital Camera

The charging error code "Err 3" on a Roomba 560 vacuum cleaner typically indicates a problem with the battery or charging system. Here are a few things you can try to troubleshoot the problem:

1. Check the battery: Make sure that the battery is properly installed in the Roomba and that the contacts are clean. If the battery is not properly installed or the contacts are dirty, it may not charge properly.
2. Check the charging station: Make sure that the charging station is properly plugged in and that the outlet is functioning. Also, check that the charging contacts on the Roomba are clean and free of debris.
3. Check the battery life: If the battery is old or has been used frequently, it may no longer hold a charge. In this case, it may be necessary to replace the battery.
4. Check the charging cable: Make sure that the charging cable is not damaged and that the connections are secure. If the cable is damaged, it will need to be replaced.
5. Check the firmware: Make sure that the Roomba's firmware is up to date.

You need to check the charging current and also the discharging of the battery in the IDLE mode.

Use a multimeter to check the charging current and also discharging rate when the engine is switched off.

The alternator and accessories must be checked.

In case the battery is not getting charged. It can be due to 3 reasons

1. The power adapter through which you are tryiing to charge the battery is u/s Check with another adapter and see if its charging then the problem is with the charger else.

2. Take out the battery and put it on another phone and try to charge it. If it is charging then the problem is with the mobile charging point and not the battery. If not charging then the problem is with the battery only.

3. Mobile charging point is not working due to which the battery is not charging to check this out just put your battery on another phone and check if its charging. If charging then you are required to get your charging point on your mobile repaired.

A new battery should have approx 12.62 fully charged
It could be slightly more
If you ever see 13 volts, on an old battery, it is gone

You need a min of 12.5, to do any testing of your vehicle, or you charge it
It should hold 12.5 or more for 3 or 4 weeks,then charge, if you let the truck sit
unused.

Sounds like your alternator isn't charging your battery.

The battery needs to be checked.If its running with jump start this indicates that mower is fine but the battery is not supporting it for normal start.In some cases the battery has low charge so getting the battery charged helps.In some cases the battery is dead so battery needs to be replaced.And in some cases the battery is new ,its charged but actually the terminals from the battery gets rusted and do not get connected so this leads the problem.So check the battery,if its low on charge get it charged,if its not getting charged then replace the battery ,if its charged and new then clean its terminals and reconnect and check. But if battery is properly charged and connected properly ,then also you see the same problem then its fault in the starter and starter solenoid.It needs to be checked and replaced.

Check if the battery is already fully charged. If it is, the charger will stop charging when battery is 100% charged.

You can check this by unplugging the charger cord from the laptop. If the battery is not fully charged, plug in the charger cord into the laptop again, start the computer and enter the BIOS. In the BIOS, look to see if you have a "battery check" and start it. This will test the charging and discharging cycles of the battery.

Check your battery and check the ground wire from battery. Make sure all your wires are clean and good connections. A bad battery will not charge and a dead battery will not charge a alternator maintains a battery not charge a battery, so charge your battery completely before checking that the alternator is working. Check all the wires going to the starter for good tight and clean connections . Hope this helps...

Solved own problem. Bad conection between pcb and battery contact pins. Reheat each battery pin on the pcb carefully until solder reflow occurs then remove heat. PDA now repaired
