I have been given a 12 volt 110 Ah leisure battery as the owner has bought a new one.The battery's voltage after being charged and at rest is now 12.20,is this battery no use,can it be reconditioned to get it up to good voltage/working condition,what can i use to rescue it or am i wasting my time?:D

    higgens,
    i hope this isn't the same leisure battery you mentioned in another thread. we frown on duplication. for the record a battery at 12.2v is not fully charged. do me a favor and tell me what a leisure battery is. i thought that all batteries leisurely lay around.:p

    Perhaps leisure ~=~ recreation ~=~ RV?

    If the resting voltage is only 12.2 after full charge (should be 12.7) it is probably damaged. If it is a non-maintenance free type you may be able to "restore" it through a controlled over charge known as equalization. Go to the host's site and read the battery FAQs.

    Re: reconditioning batteries

    There are some screw caps on top,what readings of SG should tell me that the battery can be revived,also what chemicals would i need to do this,the battery does not seem to have had much overcharging and probably not been used enough,what indicators do i need to know that it is worth having a go at restoring it's functionality,thanks,

    The only chemical you need is distilled water.

    Go through the Northern Arizona Wind & Sun online store site. You don't need to but anything from them but if you do, you will be pleased. You can learn a lot about solar products, how they are used and how they might or might not fit into your plans or budget.

    Also, Check out their Solar Information Site. Here you will find FAQs that address many issues regarding batteries, charge controllers, mount and much more.
