A digital battery meter (voltmeter) is a good tool / equipment you should not do without if you have the battery in the caravan.
What can a battery meter (voltmeter) used to:
• Measures how many volts your battery has
• Measures how much your battery booster's charging voltage is
• Meter if the battery has a relatively large voltage drop by consumption (For example, using the Mover)
• You can see how much your battery has self-discharge when the caravan is in hibernation, or in the summer if you do not use it very often
• You can see how fast loading / charge happens to 100 % charged battery
• General troubleshooting 12 It was / batteri
The above just to name a few.
There are many different battery meters, you can use a digital multimeter or install an attached digital battery meter so you can constantly follow your battery capacity, consumption M. M.
You can connect a fixed digital battery meter directly to the battery, you should be aware on the battery meter (voltmeter) consumes little power.
You can also connect the battery meter (voltmeter) an on and off switch for on / off 12 volt battery for caravan, Thus, your fixed battery meter does not consume power because the teeth while you set the switch to the on (12 volt battery for caravan). The advantage of this option, you also can see if you have set the switch to the on 12 volt battery for caravan.
it is recommended, to mount a fixed digital battery meter which is a piece of delicious extras. Fixed battery meter can be purchased from approximately. kr. 20,- to kr. 1000,- excl. mounting (2014).
A digital multimeter as shown in the above image (see caption) may be acquired for approximately. kr. 70,- (2014), and can be purchased from such Harald Nyborg.
We have installed “Victron Battery monitor BMV-712 Smart” replacing the aforementioned battery monitor – Read more about why:

We recommend you install a battery monitor, see little info. cf.. below:
• The battery charge in percent
• How many volts the battery has
• Batteriet's temperature
• Information on: the battery is ok, let up soon, charge now
• Date of the percentage of the battery has been charged to
• What caravan battery guard is mounted in

Remember that your battery capacity is reduced by cold:
A fully charged battery incriminated cold by approximately:
+ 25°C giver 100 %
+/- 0°C giver 75 %
– 18°C giver 50%
Winter Ensure battery in the caravan click here .
When the battery is fully charged:
The values apply for a temperature of about. 20 ° C.
|charge Grad||Acid Battery voltage||Voltage AGM Battery||gel battery voltage||Importance|
|100%||12,60 V||> 12,80 V||12,95 V||fully charged|
|70%||12,36 V||12,55 V||12,74 V||There must be charged|
|50%||12,10 V||12,30 V||12,54 V||charged immediately|
|10%||11,90 V||12,20 V||12,34 V||Flat - possibly partially destroyed|
|0%||11,80 V||<12,00 V||12,10 V||100 % flat - possibly destroyed|
