Its a question of Amp's..............

[Guest Rabbiteer]

Im no techy when it comes to electricity so im looking for a better explanation than the one I got today.

 

A very kind gentleman has just given me two sealed 12v 7amp batteries. I then went to the local electricity shop to be told that they dont do chargers for that type of stuff and would I llike to buy something for £ instead. He said that a 2amp charger will leave me 5amps short on an over night charge.

 

There seem to be 3 types of charges out there and I need the best info on each if possible.

 

No.1 the £50 motocycle charger that I dont really want to buy.

 

No.2 the £12 12v 6amp chargers that you can get on ebay.

 

No.3 the £5 200-300M/amp chargers.

 

I know you get what you pay for, but im looking for something that will charge these two batteries and give me about 2hrs worth of sunshine. As I know very little about sparking stuff I bow down to other peoples greater knowledge and experiance's

 

Thanks for your help,

 

Nik

Im using a "smart charger" that is meant for 12v 24ah golf trolley batteries,it charges in 4 stages,and when fully charged,will smart charge,by trickling low current as and when needed.Have charged my 12v7ah batteries 20 plus times with no probs.The chargers output is 2-4 amps,and as i'm sure you know the slower and more gradually a batery is charged the longer it will last.

I use this type http://cgi.ebay.co.uk/12-6v-800ma-Charger-...VQQcmdZViewItem

 

. Wouldn't use a standard car charger on a sealed lead acid battery, there is some that state they will charge SLA batteries, but I'd just buy one of these 800ma ones, they do the job.

Try Maplins they should have the correct charger for those batteries,

Most car chargers have the facility to trickle charge.Ive used one for years on cealed batteries .The way to muck up a battery is to leave it uncharged .
