Just pop along to any motorist discount centre who sells battery's they will do a drop test on it for you free of charge lol pardon the pun, make sure it has had a full charge the night before, I have one of these units if you have a weak battery it will detect it.:thumb:

There are many posts on all motorhome forums on this subject
This is not always true. I recently had to replace two Banner batteries and was fortunate to live near to the Banner depot. They did the drop test and informed me that the batteries were ok. I had checked the batteries myself and found that they provided only 3 Amp hours of use for each battery. Banner then agreed to bench test them and found them to be faulty in deep cycle mode but ok for engine crank amperage.
I agree with the first reply, fully charge the battery, disconnect the charger, leave for an hour to check that you have about 12.8 volts at the battery terminals. Then run a 5 Amp load till the battery shows 12 volts and check the elapsed time to give the Amp hours.
There are many posts on the forums on this, thats how I got to the bottom of my problems with the Banner batteries.:thumb:

Two true but you have to start somewhere and my snap on drop tester will certainly detect a weak battery and you can cook your toast on the bars whilst it is lol
won't do your leisure battery any favours though.
A genuine leisure battery is designed for long, low discharge currents, unlike the batteries which high current drop testers are intended for, starting batteries, which have a structure designed for short, high current discharge.
Leisure battery current is likely to be around 20amp max for a few hours, whereas a starter motor may draw 600plus amps for a few seconds at a time.
