Leisure Battery... Is It Fully Charged?


Recommended Posts

Hello Vampers

 

Have just brought a 2006 Bailey Senator Arizona, it came with a 110ah leisure battery but do not know how old it is or it's history

 

I have charged the battery but the charger never reaches a status of fully charged only ever 80%

 

When on charge my multi meter gives a reading of 13. 0v and after 2 hours a reading of 13. 9v so do not understand why charger not showing fully charged

 

Would you suggest that the battery is starting to fail?

 

The charger does go to fully charged with my car battery :unsure:

It's highly likely that its a slightly abused caravan battery, the majority probably aren't that well looked after and are allowed to deep discharge and get left for days before being charged, once this happens they will not recover to 100%.

 

Might just be me misreading but you said that voltage reads x when "on charge", did you take this reading with the charger turned off or you will be reading the output of the charger not the battery voltage?

 

What is the voltage reading of your battery when disconnected after being on charge? It is always sad you should leave the battery for 24hrs after being charged to obtain a sound voltage reading - should be 12. 7v or thereabouts

I thought the normal chargers could not get a fully charged reading of 12. 7v and would only show around 12. 5v for a not fully charged battery.

Thought also a Smart charger was needed with a charge rate of over 14v to get a full charge indicated by 12. 7v.

How many stages is the charger? It may be going through a desulphator cycle if it is smart enough?

 

You need to wait for 24 hours after taking the battery off charge and then check the voltage, if it is 12. 6 to 12. 7 it should be half reasonable.

You could always stick the battery on a good desulphator now and you may recover the battery fairly nicely, I think a desulphator is a good investment.

I assembled my own desulphator from this supplier on eBay --> http://www. ebay. co. uk/itm/12V-HP-LV-cut-off-Battery-Charger-Desulphator-Kit-/190846355622?pt=UK_Sound_Vision_Battery_Chargers&hash=item2c6f5448a6

Hi, Charge your battery for 24 hours, take it to Bushs or Brailsford and get it drop tested, this will confirm whether it's good or dud.

I am inclined to agree with you, there's another thread going on and the guy has a smart charger - I thought this op did as well, Tictag did a test a little while ago on here and found that there wasn't a great deal of difference between his onboard and his smart charger but I think you're right - in the main I'd go with a smart charger to get a full charge

Just a thought but when you checked the fluid levels was there any that was low, or if you've checked with a hydrometer did you notice any discolouration of the fluid.

Yes I did check the levels which were ok

 

Smart chargers not looking very cheap :( any recommendations that don't break the already broken bank or should I just bite the bullet and go for a new one that will last 4 years plus

 

1st things 1st will check voltage tomorrow then get a drop test done before I shell out more £££'s :rolleyes:

The smart chargers from Aldi and Lidle are fantastic but they are seasonal offers. A good unlit unit to last would be a ctek mxs 5. 0 IMHO.

I agree on the Ctek - have this model and it works very well for all my vehicles (except the 6 volt Matchless!)

Buy yourself a Hydrometer, costs a couple of quid and you can tell at a glance if you have a dead cell.

Ctek MXS 5. 0 has arrived today :D

Hope you are happy with it. Only reason I prefer the 5. 0 over the 7. 0 is that the 5. 0 has a longer warranty.

Yes 5 years, got the new red button model, nice and simple!

Only 2 years on the mxs 7. 0 - I found out after buying one :( - I later sold it, so no issues :)

My 9 year old caravan battery is permanently left in the caravan, and only gets a monthly top up from the onboard charger, and fully charges from it at around 13. 8 volts, a smart charger isn't required.

 

As said a £5 hydrometer from Halfords is worth buying to test from both charge condition and any suspect cells.

I have one as an emergency spare in case the onboard goes belly up on holiday.

What do you use to charge your CX-5 battery then :) :) :)

As you know my CX-5 failed to start twice, and has been to two different garages, the last one said they couldn't find anything wrong, but since they had it the cars been charging as I would expect, typically over 14 volts,max 14. 7v, and hasn't failed to start since.

 

According to the first dealer at Newcastle they say using a smart charger won't charge the stop start type battery, and their machine cost £3K to buy, the recommendation is to use a charger up to 17 volts which can charge at 20% IIRC of the rating, which is 110va for the diesel, confusing isn't it.

 

Obviously the caravan battery is just the good old reliable type.

Erm, yes, I have a spare 3k to spend on a battery charger :)

A battery may show fully charged but that is not an indication of the capacity. A badly maintained battery could be down to half its original capacity but still show 12. 7 volts after charging. It's how long it will supply that voltage that matters and a drop test is the best way of checking the condition.

 

A desulphating charge may cause hardened sulphate to shed from the plates and accumulate in the bottom of the cells and possibly cause short circuits.

 

All batteries have a finite life which depends on correct use and maintenance.
