Hi all, started m/h this afternoon after almost 4 weeks and all was well until I checked the leisure battery levels. after running the engine-started first time- I noticed that after running for around 30 minutes the leisure battery was only charged to 85% and as soon as I stopped the engine it started to drop immediately, to zero in about 10 minutes. Battery is 120 amp and 3 1/2 years old and the control panel shows no draw on the battery. any help welcome
take the battery out and give it a good charge with a proper battery charger, this could take several days til fully charged, in future its wise to remove and leave on charge using a smart charger, they are available from time to time for £14 from aldi, they cycle the battery so charging and then allowing to drop the charge a bit then recharging, rather than just a normal one which would just keep charging
Hi,
One thing to keep in mind with the smart charger, if the battery is really discharged ,it will not start it's cycle.
I think I am right in saying
you need to get some volts on it with a normal charger first.The smart charger will not register until there are some volts on the battery.
Regards,
Greg
and that Greg is why I said to get it on a proper charger first of all, and only then to use a smart charger for maintaining the battery for periods of laying up after that
hi all, charged battery and digital meter read 13.66 volts which dropped to 13.33 after a few hours and five days later is sitting at 13.10. any ideas anyone
Voltage will drop a few hours after disconnecting from charger & provided it maintains that charge then ok. Charge the battery once a month if it is not being used.
I know nothing about smart chargers. I do know that a battery from flat needs to have the fastest charge possible for roughly 30 mins or so. Then trickle charge. This knowledge is gained from leisure batteries that sit outside winter and summer running electric fencing. It is a wake up...the fast charge bit, then normal charge to full. After that back out they go and are continually charged by solar power. In the winter these batteries are likely to be found devoid of any power at all, and need to be roused from sleep / dead. Believe me farmers do not buy new batteries for the running of electric fencing they use old vehicle batteries.
