Jimmy Two-Jacks Posted April 23, 2016 Share Posted April 23, 2016 Hi everybody its been quite a while since I was on the forum. Things have been a bit busy with work and home so I didn't manage to MOT the 90 last year and so haven't used the old girl since last July but I have been firing her up periodically to keep liquids moving around the system. The other day I found it needed several turns of the engine to fire up as both batteries were very low on charge even though I have a solar charger. I was speaking to a friend who said that these batteries develop a memory and as such I might have a problem if they have been run low for any length of time. The batteries are a pair of 12 volt,deep cycle (liquid not gel) leisure batteries the kind with four terminals. I have a T-Max SPLIT charge system and when I pushed the monitor button after charging the levels were 12.2 volts for the primary battery and 12.6 for the auxiliary battery. I know this might be a dumb question but I don't know a thing about "eletrickery" does this sound right as I seem to remember the levels reading A much higher level in the past but that could be a memory fail on my part . Or could it be that the engine whilst running would cause the monitor to indicate a higher level because its charging? The led indicator on the charger states both batteries are fully charged? Any thoughts ? J2J Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted April 23, 2016 Share Posted April 23, 2016 12.6V is OK, 12.2 shows discharged, disconnect the two and give them a charge with a proper charger independently. Then check the battery voltages after 24 hours, they should be both over or at 12.6V really. Quote Link to comment Share on other sites More sharing options...

Frax Posted April 25, 2016 Share Posted April 25, 2016 Buy a ctek charger, they are supposed to recondition a battery and are a great bit of kit. Quote Link to comment Share on other sites More sharing options...

Well I have to say the ctek charger was a triumph, reconditioned both batteries and the primary battery has even got the green blob back in the "magic eye" indicator. Many thanks.
