Which battery does the OMG Ergos 20 take?

The OMG Ergos 20 uses the battery shown on this page. Check voltage, capacity and dimensions before ordering. If there is no published price, ask for a quote and we reply the same day.

Can I fit a higher-capacity battery in my OMG Ergos 20?

Yes, as long as it has the same voltage, fits in the battery compartment and the OMG Ergos 20 charger is compatible. More capacity (Ah) means more run time; changing the voltage or battery type without adapting the charger can damage the equipment.

How many batteries does my equipment take and how are they connected?

Many machines run at 24, 36 or 48 V with several 6, 8 or 12 V batteries connected in series (voltages add up; the Ah capacity is that of one unit). The model page tells you how many units it takes. Always replace the whole set with identical batteries of the same age.

Can I use a car battery instead of a deep-cycle one?

Not advisable. A starter battery delivers a lot of current for a few seconds; a deep-cycle battery has thick plates built to be discharged to 50-80% and recharged every day. In traction, cleaning or mobility equipment a starter battery lasts very few cycles.

📋 What we found

For your OMG Ergos 20 we found 4 compatible batteries.

📏 Battery size

The list contains batteries in different sizes or capacities (Ah). In many cases both variants fit, but it's worth checking your compartment dimensions and the Ah of your original battery before buying. Choose the one with the same dimensions as your current battery: a bigger one may not fit the compartment or the hold-down. If several match your size, the higher capacity gives more headroom for cold starts.

⭐ Our recommendation

Our recommendation

For your OMG Ergos 20 we recommend the KRONOBAT 5 PzS 775 (ordinary lead-acid, 930 Ah). It also has the highest capacity (Ah) on the list — more autonomy to power consumers with the engine off and more reserve for prolonged loads.

Before you buy: check 3 key points

Although the batteries shown are sourced from information provided by manufacturers, we recommend checking on your current battery:

Dimensions (length × width × height, including terminals and protrusions)
The dimensions shown are the maximum of the battery and include the height of the terminals, small ridges at the base and any lateral protrusions. Measure your current battery completely, from edge to edge. The new one must be the same size or slightly smaller — never larger, it would not fit in the housing.
Positive terminal (left or right viewed from the front — check the battery photo carefully)
Stand facing the battery, with the manufacturer's label facing you and the terminals on top. Locate the terminal marked with +: if it is on your right, it is "positive right"; if it is on your left, it is "positive left". Do not rely on how the battery is mounted in the car — the position is always measured looking only at the battery itself.
Technology (AGM, EFB or conventional — Start-Stop requires AGM or EFB)
Depending on the manufacturer, the same technology may be labelled differently: AGM may also appear as VRLA, AGM Start-Stop or AGM Deep Cycle. EFB may appear as EF, EFB+ or Enhanced Flooded Battery. Conventional may appear as SLI, Lead-Acid, Wet or Standard. If your vehicle has Start-Stop, the battery must be AGM or EFB — never conventional.

If you have any questions, just ask us and we'll be glad to advise you with no obligation.

Conventional Battery

This is a standard or conventional battery for vehicles without a start-stop system
