Forklift and pallet truck batteries

A forklift runs full shifts on the energy in its battery, and when one cell fails the whole machine loses performance. Here you can replace individual 2 V cells or fit out the complete battery.

You will find PzS and PzB tubular-plate cells for 24, 48 and 80 V trays, plus monoblocs for smaller electric pallet trucks and stackers.

How to identify your forklift battery

The tray label shows the voltage and the cell designation, for example "5 PzS 625": the first number is the count of positive plates, the letters give the plate type and the last figure is the C5 capacity. With that and the outside dimensions of the tray you can find the exact replacement. Also respect the minimum weight set by the forklift maker, because the battery is part of the counterweight. If the label is unreadable, count the cells and measure the length, width and height of one of them.

PzS or PzB

Both are 2 V tubular-plate cells, flooded with liquid electrolyte and fitted with caps for topping up. The difference lies in the cell dimensions and the capacity per plate. That is why you must always replace like with like, same type and same height: a different cell will not fit the tray or work the same as its neighbours. Before fitting a new cell next to used ones, fully charge the whole battery so they all start from the same state of charge.

Replace one cell or the whole tray

If the battery is fairly new and only one or two cells read low, swapping them restores runtime at a moderate cost. When many cells are weak or the tray has years of service behind it, renewing the complete set makes more sense. We sell KRONOBAT cells in PzS and PzB formats. Light pallet trucks and stackers usually run on two 12 V monoblocs in series. See the full family under traction batteries and, for cleaning machines, floor scrubber batteries.

FAQ

How do I find a faulty cell?

At the end of a full charge, measure the specific gravity or voltage of each cell. The one sitting clearly below the rest is the suspect.

Can I fit more capacity than the original?

Only if the cells fit the tray, the weight stays within the permitted range and the charger supplies the right current for the new capacity.
