How do you keep the batteries charged up over time. My 955 has one bad battery "again" and it has a battery switch. My D3 has a weak battery and I changed out the battery switch and push start to standard key start and no switch. The battery in the D3 isn't even a year old (NAPA), the 955 one is 2 years old the other about 3, and the 3 year old is dead. Guess I really need to install battery tenders as on my boat, either that or get AGM bats but that would be expensive.
What do you guys do for equipment that sits a lot?
