Mr Carfix is a mobile car battery service in Woodlands that comes to you, wherever the car has stopped, at any hour. The team will meet you in the carpark or at your doorstep, and they say they work on all makes and models, including larger vehicles that need two batteries. Before swapping a battery, they run a quick diagnosis and check the alternator, since a flat battery is not always the real fault. The diagnosis is free. Their prices depend on the battery you choose rather than on the call-out. Customers say the response is fast, including one who called at seven in the evening and had the job done straight away. Another, whose van battery had swollen and leaked, said the replacement was quick and efficient and the price reasonable. Several note that the team stayed calm and reliable on the roadside. Battery replacement is by far the most common job reviewers mention. In peak hours, a team may be held up by traffic, and the firm says it will take an alternative route. Of the five battery stores nearby with ten or more reviews, none rate higher. The nearest, Hero Car Battery Islandwide 24/7, is at the same spot and rates a little lower. The address is 11 Woodlands Close, Singapore 737853.
