Ottobock juvo b5 battery type and dimensions

[StigFan]

Hello, my batteries are deteriorating im trying to find the model to order a new couple. In the order module i read 60 ah (c20) but searching online i can see various dimensions. Unfortunately i can't open the battery compartment at this time. Please can someone help me?

THESE are what they now fit as stock.
ANY deep cycle battery that is these outer dimensions will fit. Look for LOW IMPEDANCE. And CYCLE LIFE over Ah as that is what matters.

Those physical batteries are actually too small for the job and so wont last well no matter what you do as they get hammered. Unless you dont go far.

Specs are:
Nominal capacity (1.70V/c, 25⁰C) 20Hr: 59.4 Ah
10Hr: 56.1 Ah
5Hr: 50.5 Ah
1Hr: 36.5 Ah --- So about 20Ah in normal daily use with some reserve.

Internal resistance ≤8.6mΩ (fully charged) --- (thats terrible... )

Maximum charge current 13.8 A (and why you can only charge at 13A max... charge times will be slow because impedance is high)

Maximum discharge current 660 A (max. 5 sec)

Number of cycles 2800 (50% DOD) --- (like all deep cycle batteries great cycle figures at half a discharge. A few hundered max at 80 or 90% in real world use.)

Float use / cyclic use 13.5 - 13.8V / 14.4 - 15.0V -- treat as AGM.

Charge temperature range -20⁰C ~ 50⁰C
Discharge temperature range -20⁰C ~ 60⁰C
Standard terminal Insert M6 (5 Nm torque)
Housing material ABS (UL94-HB)

Dimensions Length 230 mm
Dimensions Width 138 mm
Dimensions Height 215 mm
Approximate Weight 17,5 kg
