battery life 85ah for boat fishing

i know some of you on here fish from a boat does anybody know how long a brand new 85ah liesure battery should last mine seemed to lose power after about 55minutes and thats not continous use moved round the lake about 5 times and anchored up or is that about right.......

Sounds a bit short to me. An Endura doesn't have a maximiser so it's going to use more power than one that does but 55min is still a short time. What sort of connection did you use to the battery? A poor connection will shorten battery life considerably.

Never thought about the connection. What are you using to charge your battery? I made the mistake of using a four amp car charger and never got more than two hours out of a 120ah. A change to a proper leisure charger doubled the life.

clamp type connection no corrosion on them checked that first

Maybe an unsuitable battery type. It really needs to be a deep cycle battery to get the best out of it.

i am useing one of them smart chargers think it pulse charges when it needs it you can leave it on and it will not over charge when the charge level drops it kicks in charging i think thats how it works

is a liesure battery not a deep cycle battery then .it has a small spy hole window on the top which is green when fully charged it was still green when i got home it turns white when it needs charging which was puzzleling it shows fully charged

Not necessarily, they all have different purposes. The last but one battery I bought was designed to run a golf cart - that meant it could stand fast draining, my most recent battery is a sealed unit - I wanted that one for use in my aluminium boat (no danger of acid spillage). On the whole, with leisure batteries it's a case of you get what you pay for. You can go to extremes and pay a fortune and then you will get good performance or you could go for the least expensive but then it might not do what you want.

Best option is to go to a specialist battery supplier and talk to them before you buy. They will recommend the correct battery for your needs.
