E-scooter users frequently inquire about battery performance, maintenance, and the implications of tuning on both battery life and legal compliance. Insurance for e-scooters is a recurring topic, with discussions focusing on the necessity of liability insurance, the benefits of partial comprehensive coverage (Teilkasko) for theft and damage, and the impact of unauthorized modifications on insurance validity.

Detailed Answers:

E-scooter users often encounter issues and questions related to their devices' batteries, insurance requirements, and the effects of modifications.

E-Scooter Batteries and Performance:

E-scooter owners frequently experience problems with battery capacity and range over time. One user reported that their Ninebot G30D Gen. 1, after approximately 2700 km of normal use and an additional 1400 km with tuning, now only achieves a range of about 15 km, even in normal settings (25A), suggesting the battery might be damaged or heavily used (Source 1). Another user noted their new E-scooter showed 100% battery but quickly dropped to 77% after a few meters, providing less than 20 km range (Source 3).

When considering an additional battery, it is advised that both the original and supplementary batteries should have the same capacity and be connected in parallel for proper function and increased range (Source 1). Issues like an E-scooter not charging, even after being connected overnight, can occur, potentially due to cold weather affecting the battery (Source 1).

Concerns about battery safety, such as the risk of explosion, are also raised, with the general understanding that older batteries might pose a higher risk (Source 5). A "Liposafe" product is mentioned as a potential safety measure to contain battery incidents (Source 5).

E-Scooter Insurance:

In Germany, a liability insurance (Haftpflichtversicherung) and an official insurance sticker (Versicherungsplakette) are mandatory for E-scooters to be used on public roads (Source 4). This sticker needs to be renewed annually, similar to motor scooters (Source 2).

The question of whether partial comprehensive insurance (Teilkasko) is worthwhile for E-scooters is common. For an E-scooter valued at 450 Euros, a user pondered the benefit of Teilkasko for theft, especially if the scooter is rarely left unattended overnight (Source 2). Generally, Teilkasko is recommended for more expensive scooters as it provides better protection against theft, vandalism, and accident damage (Source 4). It "pays off" if the payout in a claim exceeds the premiums paid, similar to any damage insurance (Source 2). The HUK-Coburg insurance, for example, states it covers theft under Teilkasko, but users question whether the full value is reimbursed and how to prove theft (Source 2).

When choosing an insurance provider, HUK-Coburg is noted for good price-performance, DEVK for solid combined protection (liability + Teilkasko) with high coverage for damages including theft and vandalism, and Die Bayerische for very affordable liability offers. Allianz is mentioned as a convenient option if other insurances are already with them, offering good service and potential Europe-wide coverage (Source 4). Key factors to check when purchasing insurance include a sufficiently high liability sum (especially for personal injury) and ensuring that age and vehicle specifications align with the policy (Source 4).

Tuning and its Implications:

Modifying an E-scooter, such as tuning it to go faster, can have significant consequences for both insurance coverage and warranty. If an E-scooter is tuned, the insurance coverage typically becomes invalid because such modifications are illegal (Source 3). Even if the scooter is returned to its original state before an incident, the insurance might still be affected if it can be proven that tuning occurred previously (Source 3).

Specifically, if a display with older software is installed to tune an E-scooter, the insurance might be invalidated. If the original display is reinstalled before an insurance claim, the validity of the insurance depends on whether the scooter was in its original, untuned state at the time of the incident (Source 3). Similarly, installing a suspension system could void the liability insurance if it's considered an unauthorized modification (Source 3).

Tuning can also impact the warranty. If a defect can be traced back to the tuning, the warranty may be voided (Source 3). Some E-scooters, like the Ninebot F2 D, can be tuned via software or apps, and users inquire about the safety and potential damage such modifications might cause to the device (Source 1, Source 3). There are questions about whether police can detect if an E-scooter has been tuned, even if it's currently operating within legal speed limits, by checking settings that allow for higher speeds (Source 3).
