Diagnostic, desulphating charger + tester, Optimate 3+

Charger Optimate 3+ OptiMate 3+ desulfater-charger-maintainer is recommended for STD (with removable filler caps), sealed AGM (absorbed glass mat) & sealed GEL 12V lead-acid batteries from 2Ah to 45Ah, although it can also maintain larger batteries (it will just take longer to charge). Why OptiMate 3+? Forgot to switch off the ignition / lights or did not hook up the battery to a maintainer during off-season and now the battery is ‘dead’? There is no need to rush out and buy a new battery as OptiMate 3+ has been proven to save neglected, deep discharged batteries other smart chargers can’t.
