Hi everyone,

i'm after a decent 3 stage battery charger for topping up my battery when in the one place for more than a few days. its an exide extreme (70ah), i'll be using a generator to power the charger. am i better off charging for a few hours a day? or waiting until the battery is under 40% then charging?

after searching there seems to be a few good choices:
the c tek 7a is this enough? or would it take too long to charge?
the durst 15a

http://www.durst.com.au/ smart charger

also found this on ebay, it looks the same as the durst? anyone used these?

would appreciate any advice on chargers and approx charge times etc..

thanks

Have a look at the new REDARC unit. Charges at five amps and outperforms conventional 10-amp chargers.

Oz-designed and made. Affordable. Has conventional, calcium, and AGM/gel programs. www.redarc.com.au

Have had one on trial for six months and most impressed with it.

Can you get bigger ones? or are they too bulky. My mate has a 35 amp charger that is pretty small and i think it is marketed by Durst, do you think that would be better or not?

Charge a few hours a day - battery will last much longer.

35 amp charger overkill - including for the battery!

Whenever a Lead-Acid battery is at less than 100% charge the Lead or Lead Oxide in the plates changes to Lead Sulphate which progressively hardens. Eventually this will stop the battery accepting charge.

- so for longest battery life, always charge the battery as soon as possible.

Smart Chargers are great thats why they are the only ones I sell. Durst, Solarforce and sidewinder all come out of the same factory.

The 15amp unit will run off a 1000w generator email me for a data sheet.
