I'm with you, the replacement battery for these HUPs are Surrettes.

My question is WHY do folks still install these steel cased Pain the A*& BBs when we have 2 volt cells (UnigiII/Surrette/Crown)that have up to 2400AH @20hr rate and are easily moved by hand, fork truck, shovel! 2 volt cells is always the way to go.

We've used an engine hoist before, but for tight spaces, we built a rig out of unistrut with a small block and tackle.  Come along can be hard to use, and puts dangerous metal parts over the battery.

HUP batteries are easier to install

I've since gone to a winch system, and also try to move the batteries on rollers without taking the cells out.

I did this exact same thing for a 48v Hup one battery bank.  Engine hoist worked like a charm and my back was very thankful!

    Bill, I just did that a month ago, and it went amazingly
    smoothly. Earlier, on a similar HUP replacement, I told the
    (absentee) client that I would rent an engine hoist to lift the
    cells out of the steel cases, and he advised me that it would
    cost him less labor and travel if I bought one of the Chinese
    engine hoists from Harbor Freight for $90 and just kept it.
    Turned out to be a good application for CCC (thanks, Bob-O). A
    concrete floor, the engine hoist, a simple hand truck and a
    strong assistant to share the load made light work of both
    removal and installation - all 4,000 pounds of it, one 200 lb.
    cell at a time... so I went dancing that evening.

    Anyone ever had problems come-a-longing from above the first
    cell and if so, what's the solution?...and what are you doing
    tomorrow?
