FAQ
What type of batteries does Bosch offer?+
Bosch currently produces LiHD (High Density) and DuoPower batteries. LiHD batteries are best suited for high-demand, heavy-duty applications, while DuoPower offers continuous power without battery swaps.
Are Bosch batteries interchangeable between different tools?+
LiHD batteries are designed to be used with specific Bosch Power 18V Professional tools. DuoPower batteries are compatible with a wider range of Bosch 18V Professional tools, but always check compatibility before use.
How do I know which charger to buy?+
You’ll need a charger specifically designed for the type of battery you purchase – LiHD chargers are for LiHD batteries, and DuoPower chargers are for DuoPower batteries. Using the wrong charger may damage your battery.
What is the typical lifespan of a Bosch LiHD battery?+
With proper care and use, LiHD batteries can typically last between 1000-2000 charge cycles. Factors like usage intensity and charging habits will influence longevity; avoid frequent full discharges.
Can I overcharge my Bosch battery?+
While modern chargers have built-in protection mechanisms, it’s best practice to avoid leaving batteries on the charger after they are fully charged. Overcharging can shorten battery life.
What is the DuoPower system and how does it work?+
The DuoPower system allows you to continuously power your tool without swapping batteries. It achieves this by distributing power between two internal batteries, providing a constant energy supply.
Do I need a special charger for charging DuoPower batteries slowly?+
Yes, using a slower charge rate (e.g., overnight) is recommended for DuoPower batteries to minimise stress on the cells and prolong their lifespan. Avoid fast charging unless necessary.
How should I store my Bosch battery when not in use?+
Store your battery in a cool, dry place away from direct sunlight. A storage charge of around 50% is ideal for long-term preservation; avoid storing fully charged or fully discharged.
What if my Bosch battery isn't holding a charge?+
If your LiHD battery is losing its charge rapidly, it may be experiencing internal damage. Refer to the manufacturer’s warranty information for potential repair or replacement options.
Are there different sizes of Bosch batteries available?+
Bosch offers batteries in various capacities (Ah - Ampere-hours) to suit different tool requirements and usage patterns. Higher Ah ratings provide longer runtimes.
