I have just bought an electric hose reel, it is soo quick since I used a manual hose holder. I would like to know what amperage is better to use to power the hose rewinder as the one I have which is charged by the alternator , use a quite bit of power of the battery that also works the pump .

There is no right or wrong answer to your question as everyone's route is different.

Lead acid leisure batteries don't recharge very quickly. As most of our work is within 5 miles of home, a split charge relay only put 2 or 3 amps back into our battery on the way home. So we needed to plug a 230v smart charger in virtually every night, especially when using our diesel heater, to fully recharge the battery overnight.

 I changed to a battery 2 battery charger believing the hype this would recharge the battery faster. It didn't.

There are some window cleaners who claim that they never have to bench charge their leisure batteries. If they spend a lot of their working day stuck in traffic and/or travelling distances, then it just means the alternator has longer to recharge their leisure batteries.

The suppliers fitting a hose reel will usually go down the route of a lead acid leisure battery with a CCA (cold cranking amps) rating. (Its design comes from the caravan leisure centre where a motor mover is required.) This is a leisure battery 'halfway' between a normal leisure battery and a starter battery. It's however, a compromise. We always had good service from Numax batteries.
There are other good quality batteries in the marketplace to choose from.

Daz on the forum has a diesel heater and an electric reel. He charges his 2 Numax 105amp batteries every night when he gets home. He also has a b2b battery charger in his van.

An electric reel will draw around 25 amps when reeling the hose in. In 15 or so seconds, that doesn't equate to much power used from the battery. 10 winds would take around 1.5 amps a day. However, your battery needs for cough out a large power output for just a few brief seconds, which a standard leisure battery isn't designed to do.

We now have gone to a Fogstar Lithium 105 amp battery. My battery 2 battery charger just needed the settings changed as a split charge relay in no longer suitable to use with lithium.
Even in winter with the diesel heater going most days, the b2b charger keeps the battery almost fully charged.

I've gone and picked a great week to get back in to it    bloody (rain) typical 

Bonus is at least the customers next week will be glad to see clean glass at last.... hopefully

Sahara dust is on it's way for the next 48 hours.   Taking tomorrow off, not gong to risk wasting my time.

I noticed it today on few skylights I was cleaning....

I dont work most fridays so off anyway but I wouldn't take a day off if I had work scheduled in just because of a bit of Sahara dust.

Never been busier. Spring has started early up here, not used to double digit temperatures so customers are wanting stuff done as quick as possible. My radiator in my house sprung a leak and my washing machine needs a new bearing. Just waiting for something else to break because it usually comes in 3,s. Windows in the morning and home stuff in the afternoon, happy days.
