BATTERY TESTING TIPS ♦ Lead acid batteries should not be left for long periods in a discharged state - recharge your battery as soon as you can after use. This will extend its life. ♦ If during the winter you do not use your battery, charge it up for a day every month, this will keep it in good condition. ♦ Don’t leave your battery on charge all winter (unless your charger instructions says this is OK). ♦ Once fully charged, batteries self discharge very slowly and can be left for a month or so without any need to top them up. ♦ Keep the battery cool, don’t place in bright sunshine or next to a boiler, this may reduce the life of your battery.
