sealed 110a battery

[tony_5101931]

i have a motor mover on my van and i have just got a new battery 110a it is fully charged can i charge it with my battery charger which charges at 70a or on boost at 300a will it do it any harm it is a sealed one

I was always led to believe that batterys are better slow charged, than boost charging,i use one of these for our spare battery, its a fully automatic battery charger i have seen a battery blow the top off by being left on boost, it was a long time ago, but one i wont forget....

Go to the CC website if you are a member and download the technical leaflet on batteries. Should tell you about charging.

These are the some more links from the clubs as Ray S suggests.

This is from the CC club, Leisure Battery Charging

And this is

And this is from the Camping & Caravan Club

Looking after your leisure Battery

There is a general rule of thumb that chargers, in amps, should be 10% of the battery's amphour capacity - there's no harm with less, it just takes longer.

70A might be ok for a few seconds - I wouldn't want to put 300A through a leisure battery!

If the only charger you have is 70/300A it's probably worth investing

Don't even think about putting a 70a charger on a sealed battery unless its voltage stablilised to below gassing voltage which is about 13.6v for a 12 volt battery. I've seen all the valves pop off on valve regulated batteries when the charger hasn't been set correctly and with a sealed battery you could end up with the case cracking or it even exploding.

What sort of charger is it? One designed as a float charger with PSU capabilities such as fitted in a caravan might be ok but I'd carefully check the output voltage and take advice from the battery manufacturer before using a very high capacity charger.

Engine starting or traction batteries have different charging characteristics and ideally have battery chargers tailored to suit - it sounds as though your charger fits into that category. As said previously 10% of the battery capacity is a good rule of thumb to charge the battery up in a reasonable time without causing damage - I'd be very wary of using a charger much bigger than 25% of the battery's capacity without advice.

have a look at this

http://www.mpoweruk.com/chargers.htm
It give some info on what happens and how to charge batteries

 

[ChrisUK]

No way should you use that charger, you will ruin the battery at least and could do damage to yourself. As said above, get a Aldi / lidl one for about

Hi Sproket,I,ve got one the same as that,they are very good,won mine on ebay for

I have just purchaced a Ring charger that checks the battery condition then uses the the correct charge rate. It then goes in to trickle charge mode.It was not cheap but better than blowing the battery up!!
