What can I use this charger with?
The RSC604 is a versatile charger, ideal for a range of vehicles. It charges and protects 12V batteries up to 2.0L – including lead acid, gel, calcium, EFB and AGM batteries, and those with START/STOP technology. Use on cars, motorcycles, quad bikes, golf trollies and lawnmowers.

Why invest in a Smart Charger?
It pays to take good care of your vehicle battery. The technology is becoming more advanced – and expensive – all the time. Add to this the extra pressure on batteries from in-car electrics and charging, and the strain can cause batteries to perform below the optimum, and ultimately break.

By using the RSC604 Smart Charger, you can charge and protect your battery, helping it to last longer and perform better. The multi-stage charge cycle responds to the condition of your battery, meaning it charges at the fastest rate possible. The cycle also protects it from overcharging, as it will automatically switch to a lower voltage mode once the battery has been charged.

Maintenance charging – keep batteries in good health
The 0.8A maintenance mode setting is ideal for seasonally-used vehicles, where the battery is unused for long periods. If you’ve got a motorcycle, classic car or campervan that you mainly use in the summer, this is an essential piece of kit.

Easy to use
Simply attach to the battery, then plug into the mains, and press charge. The Smart Charger will do the rest. Supplied with fully insulated battery clamps. The polarity protection stops the battery from being damaged if the clamps are attached to the wrong poles.

Includes a five year guarantee. Register your Smart Charger at ringautomotive.com

Is this charger safe to use on so-called "Maintenance Free" modern car batteries, i.e. batteries with sealed cells that do not allow the cells to be vented to atmosphere during recharging?

From the description this appears to be suitable for all batteries clearly stating suitable for gel. However on reading the questions section you are telling a customer it is not suitable for gel batteries. Please can you clarify which it is.

Asked by: Confused
Hi, apologies for this, I have updated the other answers to reflect that this is indeed compatible with gel batteries, in line with the manufacturer's specifications.

Will this unit be damaged by starting the engine while it is connected. I want something to use to charge a small genset battery, which does not have an alternator of its own. Obviously can be a.c. fed once the set is running. Thanks

Asked by: Dick
Unfortunately we are unable to guarantee full compatibility for this item in your intended device as we have no data regarding that particular make/model, it may be worth checking with your manufacturer.
