Keep your battery fully charged with our Trickle Charger by maintaining the performance of your battery before any problems arise.

With most of us staying at home and our cars inactive for long periods, a trickle charger will prevent your car battery from losing enough charge to stop it from working.

The low-voltage charge is designed to improve the health of your battery on a long-term basis, with a reduced risk of overcharging.

Although alternators maintain batteries that are near a full state of charge they’re not designed to recharge a heavily discharged battery.

Trickle chargers top-up batteries at the same rate as self-discharge; the slow process uses a low voltage so the devices can be left for an extended period of time.

We recommend a 12V battery trickle charger or a solar-powered trickle charger.

​Smart battery trickle chargers

As well as discharging, analysing, conditioning and performing cycle tests on your batteries, smart trickle chargers typically charge your battery in the same amount of time as a rapid charger.

Our price £56.29 (includes VAT)

Solar-powered trickle chargers

These charge at a rate that's equal to the self-discharge rate, so they’ll keep your batteries charged at the proper level.

Our price: £92.40 (includes VAT)


How to use a trickle charger:


  1. Make sure your car is parked in a well-ventilated environment, turn off the ignition and remove the key.
  2. Select the appropriate power settings for your battery using the device’s controls – most use 12 volts.
  3. Scrub any corrosion that’s on the posts of the battery with steel wool to ensure a better charging connection.
  4. Ground the charger by attaching it to a metal part of the engine or chassis to reduce the risk of an electrical surge. On newer cars there may be jump posts specifically for this, it’s worth checking your vehicle handbook if you’re unsure.
  5. Take the red clip and attach it to the positive terminal on the battery.
  6. Connect the black clip to the negative terminal on the battery. However, on a modern vehicle, the battery negative should not be used as this may bypass the battery management sensor. Again, always consult the vehicle handbook
  7. Your charger should be turned off and now plugged into the socket.
  8. Turn on, charge, and make sure there are no sparks or heat given off.
