Autosleeper Broadway Leisure Battery

Hi All,

A quick question I have placed a brand new tested leisure battery onto my 2016 Broadway and after one week with no use the voltage has dropped to 4.5v anyone tell me is this normal or what may be draining the power? Will connect.mains up for 24hrs before we go away and see what happens but seems weird it's dropped so fast. Have used a battery tester on the battery and all seems good.

If by “battery tester” you mean one of these

or a multimeter then they will be giving you reasonably accurate readings.

If you are reading the voltage from your Sargent control panel then those numbers are probably totally inaccurate.

In my experience, voltage readings on a Sargent system may not be highly accurate, but there's no way that they are that inaccurate! Current readings are a different matter - often wildly out.

No - it's not normal. Yes - use an independent means of testing to see whether the voltage on the battery itself (measured at the battery terminal) is the same (roughly) as shown on the display panel. Possible causes and actions will be dependent on that.

Possibly the Sargent display as ran engine firb10mins all charged thnx guys

Something not adding up here for me.....

If the LB voltage was 4.5v (how was that measured, multimeter over the terminals??) then running the engine for 10 mins won't have fixed it. It may have, temporarily, raised the voltage due to the alternator output voltage being seen, but no possible way a flattened to 4.5v battery is going to be charged in 10mins

Best way is, disconnect the LB from the van, it can stay in place just remove both terminals.
Wait 1 hr or so, then measure the voltage with a multimeter. Record it.

If not 12.7 or so, connect it to a main powered charger and charge it for 24 hrs.
After that time, switch off the charger then wait  1 hr or so. Then measure the voltage, record it

It, if the battery is healthy, now read 12.7 to 12.8 volts, the fully charged lead acid battery voltage.

Let us know what the result of this is please

Our Sargent panel frequently tells me our starter battery is at 3.6V even though I know it isn’t. It even does it with the engine running too. The only accurate way to test a battery voltage is with a decent multimeter (or voltmeter) wired across the terminals

Anyone know what the red unmarked switch if for near to the leisure battery by the wardrobe panel . I'd send a pic but this sore won't accept pics from.my phone. It's an Autosleeper Broadway
