Next morning the battery showed 11.96v, so I guess the either the battery is failing

If it is standard type of Lead Acid Battery, ( gell or liquid ) then the voltages being measured strongly indicate a dead cell.
You could check with the manufacturers in case the battery has some unusual chemistry that makes its normal off load voltage 12 volts and not the usual 13.4 nominal of lead acid batteries.

Thanks Bernard,
The battery in questions is a SLA item by Sunnyway (China) SW12170 (12v 17.0 Ah).
I am assuming that it is the cheapest sort of battery for this application.
If it is faulty, I have to make my mind up whether to replace it, or get another booster kit.
I have just come in after physio, so will follow your lead shortly.
many thanks
Looking at the voltages quoted in earlier posts seems it is charging. I would expect any battery to reduce voltage when left over night that is normal.Thanks again folks,
I had it on my normal charger yesterday from about 12:00 noon till I went to bed at about 12:30 this a.m.
The charger started off at about .8 amp, and within minutes went down to .5 and settled there.
The batt measured 12.62 volts when I left it last night,,, and this morning shows 12.36v. - so it is losing charge just by standing in my kitchen.
Good the idea is power from charger can be converted to two types of energy. "Chemical or Heat" while battery is cold it means it is charging all power is causing the chemical change as wanted. Once fully charged then it will heat up. Talking about heat of battery not charger.[/quote]The battery dosn't get hot - or even warm - when on charge. I kept feeling it when I started using the external batt charger as opposed to the charging system of the kit.
