Useful advice for storing batteries over winter
Batteries employing newer technology such as lead-calcium, gel or AGM have a much slower self-discharge: 2% per month compared to 10% for conventional batteries for which can be damaged by extended wintering.
It is therefore necessary to follow a few rules that will prolong their life and their effectiveness.
- Make sure they have a good charge at the start by using a battery charger if possible.
- Store your batteries in the cold. Contrary to popular belief, they will lose charge more slowly being stored in the cold than in heat during the winter.
