Don’t charge an alkaline or zinc-carbon battery, they are not designed to be charged.

When it comes to frequently used remotes or appliances, the batteries are quite fast changed after the appliance or remote stopped working, because it is easy noticeable. However if the appliance or remote is not that often used, there is a risk of over discharge and leakage in that appliance. 

A battery is a chemical product which produces electricity by chemical reactions at its inside. These reactions and its inside materials do deteriorate over time.

Use equipment's recommended battery, always insert batteries correctly, please avoid short circuiting at all time, always use same brand, type and expiry date batteries in you appliance, take care of the battery, always turn your equipment off, be sure the batteries fit perfectly in the battery department, remove depleted batteries at once, always avoid high temperature, high humidity (water etc.) and direct sunlight, always wash the effected skin, eyes and clothes with copious amounts of taped water, keep batteries away from children and babies at all times, change out battery all at once.

The ideal temperature for our primary batteries is between 5°C up to 45°C. 

You can download the manuals of our chargers on our website.

There are several possibilities why a battery can feel hot or heat up: when the battery is short circuited (in a purse or in a drawer), when the battery got a severe shock (has fallen down) or when a battery is wrongly inserted in the battery box.

Please store your batteries in dry conditions and avoid high temperatures and direct sunlight.

There is the possibility that the measurement was executed wrongly. Please make sure that the plus pole and the minus pole are measured with the corresponding measuring ends of the voltmeter. If they are switched, there will be a negative voltage. If the poles of your voltmeter are correctly connected, there is a possibility that the battery suffered a phenomenon called “polarity reversal”. This is a rare phenomenon that can happen at the end of a discharge with 2 or more batteries in series.

No, please never mix batteries from different types, brand or equipment.
