OptiMate 5 charger for Start/Stop batteries
While start/stop delivers environmental benefits, it places greater demands on the vehicle’s 12V starter battery. Repeated engine restarts during journeys can accelerate battery wear, particularly in cold weather and in cars used for short trips.
The result can be frustrating and costly - both financially and in wasted time: flat and weakened batteries remain one of the single biggest causes of roadside recovery on UK roads, accounting for almost a quarter of AA call-outs.
The new OptiMate 5 Start/Stop battery charger has been developed specifically to address the problem. It delivers a higher 4A output to cope with the more powerful STD (with filler caps), AGM, GEL (sealed VRLA) and EFB lead-acid batteries fitted to start/stop-equipped cars. It doesn’t just charge; it diagnoses, recovers, tests and maintains the battery automatically.
It can recover deeply discharged batteries from as low as 4V - often encountered in vehicles used less frequently. Once charged, OptiMate’s fully automatic maintenance programme keeps the battery in optimal condition without the risk of overcharging.
For owners, it really is a case of connect and forget. OptiMate 5 Start/Stop is fully automatic and safe to leave connected long-term, with full electronic protection for both the battery and the vehicle’s sensitive electronics. The energy-efficient design keeps standby power below 0.5W, making it suitable for 24/7 use.
It’s also IP54 weatherproof and tested for operation down to -40°C, so is safe for unheated garages and sheds, and even outdoors.
The OptiMate 5 Start/Stop is available now, priced at £79.90 (inc. VAT), and is supplied with battery clips and a weatherproof battery lead. It comes complete with a three-year warranty.
