It turns out that the electric bicycle battery runs out quickly even though it is fully charged!

the problem of the electric bicycle battery running out quickly

One of the common complaints of electric bicycle users is that the battery runs out quickly, although when it is recharged it seems to be full quickly. This is often confusing, especially when the indicator on the charger and speedometer shows the battery in full condition, but when used it only lasts a short time. The following is a complete explanation of the causes and solutions.

Characteristics of Electric Bike Battery Problems

Many users report that the electric bike is only charged for 15 to 30 minutes, but the indicator is already showing the full battery (the light on the charger turns green). When used, the electric bicycle can only cover a very short distance before it runs out of power. In fact, under normal conditions, the electric bicycle charging process should ideally take between 8 and 9 hours. If the charging process is only short but already shows the battery is full, it is very likely that there is damage to one or more battery cells.

Battery drop (soak)

Most electric bikes use 4 or more battery cells. If one of the battery cells experience a decrease in performance (dropping), then the system will still show that the battery is full even though the original capacity is not optimal. This causes the bike to run out of power quickly.

Battery life

Long-term use can cause a decrease in battery capacity. Over time, the battery’s ability to store energy decreases, even though the indicators show as if they are still full.

Improper Charging Habits

Charging too long, for example overnight without supervision, can shorten the battery life. We recommend that the charging is done regularly and no more than the recommended time. It is recommended to divide the charging process into two sessions, for example 4.5 hours – rest – 4.5 hours further, to make it more durable.

Solusi Mengatasi Baterai Cepat Habis

Check the battery cell condition

Disassemble the battery and check each cell using a measuring device or take it to a trusted battery or electric bicycle shop. The technician will help check which battery cells are still feasible and which should be replaced.

Perform battery sampling (if necessary)

If only one cell has a problem, a jemperan technique can be done. However, if the condition does not improve after the jemper, the replacement of the battery is the most appropriate solution.

Replace the battery selectively

Not all batteries need to be replaced. Just replace the damaged cells, according to the results of the technician’s checks. This can save costs compared to buying a new set of batteries.

Estimated battery replacement cost

For the original type of electric bicycle battery, the unit price can range from Rp. 350,000 to Rp. 400,000. Therefore, it is important to carry out an inspection first so as not to replace the entire battery unnecessarily.

Tips Merawat Baterai Sepeda Listrik

• Avoid charging the battery overnight or more than 9 hours.
• Use the default charger or according to specifications.
• Store the electric bicycle in a place that is not damp and the temperature is stable.
• Perform periodic checks on the battery every few months.

By understanding the causes and solutions to electric bicycle batteries that run out quickly, users can be wiser in taking care of their electric vehicles. Routine maintenance and checking is very important so that electric bicycles can be used in the long term without much constraints.
