Battery repair and replacement
Battery repair and rebuilding in Riga: power tools (Bosch, Makita, DeWalt), robot vacuums (Roborock, Xiaomi), Dyson cordless. 6-month warranty.
A battery that drains in minutes, a device that will not hold a charge, will not charge, shows no charge indication, a swollen or leaking case, a need for more capacity or a non-standard size pack — this is what we do every day. We rebuild and assemble from scratch batteries for robot vacuums, cordless vacuums from Dyson, Xiaomi and Dreame, robot lawn mowers, power tools from Bosch, Makita, DeWalt and Metabo, emergency lighting, medical and industrial equipment. Packs range from simple 2-cell Ni-MH sets to complex Li-ion packs with BMS boards and thermal sensors. We only use trusted Li-ion cells — no anonymous "equivalents", as it is a matter of safety and service life; specific cell brands are listed in the FAQ below. If the BMS board itself has failed, we repair it or fit a compatible replacement. The process: bring the device or the old battery to our service centre — no appointment needed, Mon–Sat 09:00–16:00 — we test the battery, identify the type and capacity, agree the price and timeframe with you, and get started. Typical turnaround is 1 to 5 working days; non-standard configurations may take longer and we will tell you in advance. Battery replacements and custom builds carry a 6-month warranty — longer than most ready-made batteries sold online.

Customer reviews
“Repaired on the same day, very good price as well.”
“Special thanks to master Nikolai for his high level of professionalism! The hydraulics in my Norwalk 280 juicer needed repair. The repair was completed without ordering parts from the USA!”
“Very good technician Boris, including home visits. I have a very heavy and large TV, the technician came, diagnosed the defect, left with the faulty board, repaired it and brought it back and installed it a couple of days later. The TV works like new again.”
“LED Samsung 48 TV. They fixed many defects at a reasonable price — another place quoted 3 times more. Recommended.”
“USSR-era interior, but professionals work there.”
“Four years ago I sent my TV for repair. All the LEDs inside needed replacing — they were no longer in production. They found new ones and repaired it. The TV still works. Another repair shop kept the TV for three months without even trying to fix it.”
“Even appliances that other services refused to repair are fixed here. The latest — even a water pump's electronics! Excellent, thank you!”
“We had our range hood repaired. The repair was done quickly, with quality, and at a fair price. We recommend!”
“Excellent customer service, special thanks to technician Boris, who helped us fix our TV even over the phone, even though we thought we'd have to buy a new one. Thanks again.”
“If some old but nostalgically beloved appliance stops working, this is the right place. They can repair irons, music centres, TVs, and probably a lot more. I even saw someone bring in a washing machine.”
