do i need to charge it every night only used it half a day should i put it on charge or will it be fine

Hi Ritchie. A lot will depend on the AH (amp hour) rating of the battery, Current drawn and the number of hours worked.

EG setting the flow controller around 50 - 60 flow rate, the pump will draw 3 - 4 amps per hour. times this by the time worked to give you the approx amps used.

Battery manufacturers recommend the battery should not be depleted by more than 50% of its capacity or for volts to fall below 10.5v
So if you have a 80AH battery, you can drain 40 amps in theory before you need to charge the battery. Bear in mind the lower the amps the longer it will take to recharge. Also as the battery nears full charge it will take less amps from the charger.

Based on my example of 3 - 4 amps and hour used an 80AH battery could give you 10 hours work before it needs recharging.
A better guide is the volts shown on the controller at the start of the day I would suggest volts should be 12.5 or more.

think mine is 115 ah battery

I use a leisure battery I think it 100 amp hour,I charge every night,after using it for approx 6 hours on a one man system.
Never had any problems with battery and it's coming up to three years old

or another way of saying it is CHARGE IT EVERY NIGHT TO BE ON THE SAFE SIDE!

OK with a 115AH battery you have 62.5 amps to play with so If you use 4 amps and hour you are going to get 15hrs approx. so Certainly charge every other day. If you have a heavy usage day then a recharge that night would be a good idea.

Every 2-3 days, take into account the pump is not in constant use when walking from one window/house to another.

I found my battery's last longer charging every other day , when I charged every day they lastest a lot less time
