Seven tips for extended battery life!
Full power for longer and no starting problems in winter!
How to get even better performance from your Banner battery.

1. Keep it active and on the move.
Inactive batteries start to discharge in a process during which lead sulphate forms of the battery plates and obstructs the current flow. A device like the Banner Accucharger keeps the battery in shape and prevents sulphation.   


2. Keep it clean.
Ensure that the surface of the battery is clean and dry using an antistatic cloth. Moisture in the engine compartment causes current creepage, which consumes energy. In addition, do not use any so-called improvement agents.


3. Keep it safe in winter.
Battery starting performance declines in cold weather. Therefore, in order to have sufficient power, switch off additional consumers such as blowers and the heating until the engine is running. Moreover, turn them off before shutting down the engine.


4. Keep it running marathons.

During short trips cars often require more energy than the dynamo can generate and recharge, which means that the battery is subject to constant discharging. Therefore, if possible take the car out for longer runs in order to charge up the battery, or even better treat your battery to an external compensatory charge using a Banner Accucharger. The environment will be most grateful.


5. Keep it fit for winter with an extra charge.
Frequent short trips in combination with stop and start traffic reduce the energy level of the battery during every start and drive. Give your battery an extra portion of power with external charging, especially before the first cold winter weather arrives. 


6. Keep your convertible in trim during hibernation.
Are you mothballing your car for the winter? If so and the battery is to stay in the vehicle, then remove the negative terminal. The battery must remain dry and cool (but frost-free). Recharge at the latest when an open-circuit voltage of 12.5V is reached. The solution for these requirements of seasonally driven cars is provided by regular compensatory charges and charge retention using a Banner Accucharger.   


7. Keep a Banner booster close at hand.
One thing should be noted from the outset. Namely, that in view of the sensitive electronic components in the vehicle, as a rule starting assistance should only be given by means of a Banner Booster. This is because start assistance from vehicle to vehicle can lead to voltage peaks during the disconnection of the terminals, which can damage or even destroy car electronic systems.


Get through the winter safely and well!
