Howzit,

Can any one give me an idea on how long one can run the battery using  a 34lb thrust trolling motor before it runs dead. I intend getting me  a small 2 man inflatable and a deep cycle battery to run the trolling motor.

You can run all day at low speed on a good 75Ah DEEP CYCLE battery. But flat out you will only get around 2.5 hours.

Invest in a U.S Battery 130Ah (DC31XC)and you will be able to fly around the dam all day long flat out, and then some.

prove it...i have seen some backyard experiments...done with different aged batteries...but never actual proof from a supplier like deltec who sells both 105 amp/hr and the 130 amp/hr deep cycle batteries.

i would like to see an actual test done using batteries which are both new...charged with the same charger and discharged using the same load.

thanks fishton, been following your posts, you are always available when people need advice. Keep up the good work.

If you don't have the trolling motor yet, you could consider the 24V ones and use two batteries. The advantage would be that you draw less power and you improve battery life, the extra battery is the drawback. Remember a battery drawed flat each time does not live as long as one you only deplete 50% each time.

Always ask for the battery spec for the type of battery, it will indicate the life expectancy vs discharge cycle, i o w how many times can you recharge at what discharge depth. Some batteries are better suited to work like that or you will buy new batteries every few months.

Here is my ... quote cranky - "some backyard experiments"

My biggest challenge was to find something that draws a very constant current, but not too high and not too low.  I came up with a eurolux energy saver spot lamp powered by a 1000 watt power inverter.  The constant current was between 1.5 and 1.6 Amps.  This is roughly the same current you would draw on a slow steady pace fishing the shoreline on your trolling motor once the boat got a little momentum.  Ideally I would have liked to pump the current up a bit every now and again to simulate varying speeds on the boat, but how do you replicate this 100% for each battery?  So a constant 1.5Amps it is for now.   The cut off voltage for the test was 11.4V.

Before each test, the batteries were given a full charge and reconditioning by my CTEK XS7000 charger.

1. M27MF: (bought February 2009)

It has a capacity rating of 105Ah and lasted a total of 15 hours and 20 minutes.

2. M27MF: (bought March 2010)

It has a capacity rating of 105Ah and lasted a total of 21 hours and 42 minutes.

3. Yellow Top Optima Y75L: (bought in May 2007)

It has a capacity rating of 75Ah and lasted a total of 40 hours and 55 minutes.

4. U.S Batteries 31DCXC:  (bought March 2010)

It has a capacity rating of 130Ah and lasted a total of 63 hours and 23 minutes.

Conclusion:

I was nothing short of shocked when the M27 conked out at just over 15 hours.  So I did the test again with the second one of the pair – very much the same result.  The first six months of this battery’s life it was charged with an old standard type charger that back then was regarded as a high end charger.  Did this possible damage the battery?  The next question is, is the M27 the same battery it was some years ago?

The Optima is a fantastic battery and its reliability is nothing short of exemplary.  Even after 2½ years of charging abuse on an ‘old school’ charger before I got the pulse charger, it still offers great storage capacity.  The only down side is the retail price tag of R3600 excl. VAT

I expected the 31DCXC to do well, and that it did.  I will do this test again every 6 months to see how it compares to this first test, after 5 months of use nearly every weekend, to see how it maintains its capacity.  I was asked on the weekend of the Albert Falls Tournament "Why would anyone want such a high capacity battery as a bass angler?"  There are a dozen really good reasons, all of which are very obvious, but for me it is the fact that I am not pushing my batteries every time I go out.  Hopefully this will ensure a longer life span of the battery - and that's money in the bank!  Not to mention that at R1999 it's a great buy.

Ok hier is my vrae as ek so voorbarig mag wees.

Is die Deltec 130 a/h batery goed wat Outdoor Warehouse verkoop, en sal die Ctec XS25000 charger die beste kopie wees as 'n charger vir my gebruik? Rede hoekom ek vir die 25000 wil gaan is die tyd (3 ure) wat dit sal vat om 'n 100 a/h batery tot 80% vol te charge en (ek het ook 'n Deltec 105 a/h batery wat nou sy kop begin afdraand buig) om die tweede batery op dieselfde tyd (is dit moontlik en hoe hoe kan ek dit doen?) te charge as ek die Genie run of as ek by die huis kom na ek gekamp het.

Ek gaan die twee baterye inspan tesun my inflatble se trol motor, aasboot & remote se baterye, vrieskas/yskas en ligte in die aand. Omdat ek twee baterye sal hê wil ek my yskas/vrieskas meer kere van die inverter af hardloop om te verseker dit bly gevries want daai baber aas VROT as dit afgaan en ek sukkel te veel om dit in die hande te kry om net so 'n loss te vat. Soos ons weet gaan die inverter dus baterye vinniger vreet, maar omdat ek die genie het kan ek hulle elke dag vir so drie of dalk minder ure optop.

Mond vol maar ja enige hulp sal BAIE waardeer word, of pak ek nou weer te veel dinge op een slag aan?

Hier is die Ctec XS 25000 se specs as dit sal help:

Voltage / 170 - 260 VAC, 50-60 Hz.

Charge voltage / 14.4 V

Charging current / 25 A max.

Current Ripple / < 4%

Current, mains / 2.9 A rms at full current

Ambient temperature / - 20°C to + 50°C

Charger type / 8 Step fully automatic

Type of Batteries / All types of 12 lead-acid batteries

Minimum battery / 50 Ah

Max battery charging / 500 Ah

Max Battery maintenance / 500Ah

Cooling / Fan

Back current drain / < 2Ah per month

Insulation / IP 44 - outdoor use

Dimensions / 233L x 128W x 64H mm

Weight / 1.4 kg

Warranty / 2 Years

i dont need to...i am not the salesman trying to sell batteries...BTW nor am i an agent for deltec...

however i would love to know how a 130amp/hr out last a 105 amp/hr by 48 hrs...becuase my limited knowledge about batteires and what deltec have told me this sounds like a bit of a tall story...thats why i mentioned i would like to see some credible  facts.

tyson dont forget you need a good charger for the battery... they dont come cheap so make sure you budget for the charger.

you need to take into account a battery i wouldnt get smaller than a 105 amp/hr...a good charger...there are some good makes for around R850 but it all dpends on your budget...if you have the money to spend then go all out...and get the best of everything...but if your budget is limited then shop around i had a person offer me a deep cycle battery for R850 this week...a 3 stage charger for around R850.

i have a deltec 105 amp/hr battery on my kickboat and i did a round trip at hazelmere...it took me 4 hours with my 34 lb trolling motor on 5 most of the time and spent an addtional 2 hours on the water just idling around and the green light was still on.

according to the deltec dealers i have spoken to they say...it is good to keep your battery well used...it is when the battery stands that problems start especially if the battery is not fulled charged when left for a period of time.

Cranky,

It seems those colour indicators are not very reliable, yes deltec. My one friend also got a bunch of them and half those indicators are not working. We have some batteries that shows green but are completely flat, and ones that just stay black. You can aparently have them replaced, but just ignore and use a voltmeter.

When your battery voltage hits 12V under load you know it's time to be almost home. At 11.8V a 12V battery is considered flat, in fact it's going to drop in voltage fast.

You have to measure the voltage directly on the battery poles.

Charge the battery once a month, if ist stands for a while sulfation begins to develop and thr battery loses it's capacity.

Sulfation is small crystals that forms on the battery plates and has an insulation effect.

Skuimkop,

Jy kan nie die battery in 'n kort rukkie vol stop nie, dit neem tyd vir die battery te laai. Ek sou se minimum 6 to 8 ure per dag.

Dit is die rede waarom 'n voldoende grootte sonpanneel beter sal wees, vandat die son opkom tot wanneer hy gesak het laai hy jou battery en loop bv die yskas en laai ander klein goeters bv flitse ens.

In SA behoort jy 7 / 8 ure te he. Jy kan die gennie gebruik as dit bewolk of sterk bewolk is.

i agree...check out the front panel...my first bass boat.

i prefer using the voltmeter with the red/yellow/green indicator.

Fanie dankie vir jou reply en ek weet nou al jy is 'n man om te glo as jy 'n ding sê maar lees asb bietjie deur die attachment wat ek vir jou aanheg. Daarin sê hulle duidelik dat die 25000 die baterye tot 80 % charge in 3 ure waar die kleiner modelle langer vat. Ek kan verstaan dat jy net soveel energie in net soveel tyd in 'n batery kan terug kry maar praat hulle dan nonsens? Daai is hulle top of the range charger so is hy nie dalk net 'capable' om dit te doen waar ander nie is nie? Ek gaan vir jou 'n skaal probeer kry van hulle verskillende modelle.

Hi Skuimkop,

Ek weet van die C-tek laaiers en daar is ander wat elk ook hulle claim to fame het.

As jy met 80% begin die battery gebruik, waar eindig jy aan die einde voor hy weer die volgende keer gelaai kan word ?

As jy die battery net 80% vol kan laai, gaan jy nie veel lewensduur van die battery kan verwag nie, en as ek raai gaan jy na 'n paar dae agterkom die battery wil nie meer nie. Geen loodsuur battery wil in 'n half ongelaaide toestand werk nie.

Sommige batterye word wel ontwerp om tot 'n mate sulke behandeling te kan verdra, maar mens moet besluit wat is belangriker, die ekstra sonpanneel wat byna net soveel soos die battery kos, of om die battery gereeld te moet vervang.

Oenslynlik lyk dit asof die solar paneel die duur opsie is, maar as jy in 'n relatiewe kort tyd moet begin batterye koop word dit duur.

Die ander nadeel van gennies is hulle word nie oral toegelaat nie omdat hulle raas en verg instandhouding, laat jou hande na petrol of diesel stink wat visse afskrik, brandstof saamry en en en. Die solar paneel mag niemand jou verbied nie, dis stil skoon en verniet. Die enigste ding is jy moet die panele beskerm sodat diefstal nie oorweeg word nie.
