Triumphrider it amazes me how many people think a battery looks after its self. As for the if it works don't fix it spot on we have a service regime that our techs have to stick too we do all our own repairs (we do have all the laptops etc) but the dealers only get involved when it's warranty work. Even running 24 hour shifts we get at least 10 years out of our kit before it gets replaced some like our Yale C/B trucks far longer as they just don't breakdown we are putting new batteries in them all now which will extend there lives by at least another 7 years. With 500 trucks on site it would cost the company a fortune if we didn't maintain them properly especially as we have another 9 sites around the uk with the same amount of kit in them. Look after your kit properly and it pays dividends
