Have just checked voltage, it has gone down to 12.40. after half an hour,Which is not as bad as last time!!!!!!!

Nick, This is what started things off a few days ago i wrote the on forum. "I installed 4 of these last March, these last weeks according to my Smart gauge have dropped from 100% to 72 %, i only use a couple of LED light and a water pump. Today i put 4 x 10w bulbs on for about 30 minutes and the charge went from 83% to 72%. I have checked to make sure nothing is switched on or working which i don,t know about. I am on shore power so not using inverter etc" I still have this problem, I have left the battery charger off last night, just to see what happens! The Smart gauge voltage (Which i have double checked with a volt meter across batteries and seems pretty accurate) was the same as last night.12.70 to 12.80. after turning on 2 x LED lights and using water pump to fill kettle went down to 12.60 in about 20 minutes! i will now turn 4 x 20w G4 bulbs on and see what happens in Half an hour. Thanks

Hi Nick Thanks for your help. The readings for my batteries were- Battery No 1 1.305 1.295 1.305 Battery No 2 1.295 1.285 1.295 Battery No 3 1.300 1.295 1.300 Battery No 4 1.300 1.290 1.295 Seems strange that the middle cell in each battery is the lowest!!!

Nick The temperature is 10 degrees now! so i would have said about 8 degrees when i measured them. This is ongoing as in my posting a couple of weeks ago when i put some lights on and the Smart gauge went down to 11.9Volts in a matter of half an hour!! Where you advise a Desulphation charge of 15.5v, my battery charger will only do 14.8v!! I am still struggling to solve the problem!

Hi Nick This is their reply! Dear Ralph, These values can not be possible. The specific gravity can not be higher than 1,277. Check page 17. Have you add any liquid to the batteries? Can you let the batteries disconnected 24 hours? And check the values again? Regards,

H Boredrider Thanks for that! That is exactly what i did, set up on the lowest line using Distilled water. I have results of four batteries, the lowest reading is 1.285 and the highest 1.305. I really don't know what is going on!!

Having been losing the Charge on my Trojan T105's i have purchased a refractometer. I have been in touch with Trojan in USA. They wanted the Specific Gravity of my batteries after being disconnected for 2 hours. I have results of around 1.300 which i am told is impossible! Can anyone tell me which scale on refractometer you zero up on? I zeroed on the lowest reading on the antifreeze scale, is this correct?

Thank You Old Goat Think i will stick with towergate then!

i have had a quick look, seem about the same cover, i have had hese quotes so far Towergate £244 Collige £298 Curtis £198 Makes you think! You don't know how good an insurance is until you need it!

Has anyone got their insurance through Curtis Marine? Backed by AXA. They seem about 20% cheaper than others! Any opinions?

This morning the smart gauge readings are 100% 13.30 to 13.35 volts. Thanks again everyone for your help. Just to add. After a days charging. I turned battery charger off for a few minutes, when turned back on smart gauge went to 14.75 Volts

Just an update. Smart gauge shows charging at 14.65 to 14.70 now.

Hi I have suspended 1 inch thick Kingspan half an inch below my floor, above the ballast,This allows air to circulate in bilge, but stops cold air rising, has made a big difference in temperature at floor level.

Thank You for that By' eck. I aws going to turn it off before bed, but i will leave on , do you think that this will put the batteries right?

Thank You Proper Job I will do that when i can get another pair of hands. Will keep you informed!

Thank you all for your help! I am good mechanically minded but my electrics are VERY basic. I have just tried to reset Smart gauge using online installation guide, I disconnected both live and neutral wires hoping that it would reset itself, when reconnected.the installation guide says to select battery type using status button, this does not work! I have put a meter on the batteries they read 12.9v which agrees with smart gauge.

I have just checked battery charger settings are for"Non Sealed Lead Acid batteries" The charger is Sterling Advance Digital 4 Step Switch Mode Charger/Power Pack Pro Digital Range. Now charging at 14.55 to 14.60 on smart Gauge

Hi The charger is set up as for normal 12v 135 AH leisure batteries, if this helps? FYI the charger has just gone to 14.25 - 14.30

Hi Nick Thanks for your help. I have a Sterling Advanced digital 4 step charger, when charging will go to 14,15 to 14.20 volts. I really don't know about 15 volts!

Hi I have a sterling battery charger permanently connected. which i use when the smart gauge gets down to about 75% I have checked the water levels , have not had to top up since i installed them March last year. The connections are all tight and clean. The batteries are inside the boat. I have been on boat all winter, its only the last few weeks that the smart gauge has shown the percentage drop very quickly sorry but i don't know much about checking the batteries!

Has anyone had any problems with these batteries suddenly not holding a charge? I installed 4 of these last March, these last weeks according to my Smart gauge have dropped from 100% to 72 %, i only use a couple of LED light and a water pump. Today i put 4 x 10w bulbs on for about 30 minutes and the charge went from 83% to 72%. I have checked to make sure nothing is switched on or working which i don,t know about. I am on shore power so not using inverter etc. Thanks

Hi I have gone through 3 battery chargers in the last 2 years, 1 x RAC and 2 x sealey autochargers! I need it to top up a battery on a stored car! Can anyone recommend a reliable charger? Thanks

I have this problem, have only used Phurnasite smokeless for the last 3 years but get a large build up of "Concrete" in the bottom part of my flue, I assume that it is the cement dust which is used to bind the brickets!

I think this boat used to have the name Christabelle, It has been moored around Brockhall for some time.
