Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Wiper i70 / i100S / i130S — 25.9V Li-ion Replacement Battery (015E00600A)
This is a 25.9V 2600mAh (67.34Wh) Li-ion battery for the Wiper i70, i100S, i130S, and Wiper Premium i70 cordless lawn mowers. It replaces OEM part number 015E00600A. The pack slots into the same bay and uses the same BMS handshake protocol as the original.
- i70 / i100S / i130S platform fit: These models share the same 25.9V battery rail, connector pinout, and BMS communication protocol — which is why one pack covers the full range. Swapping between them requires no adapter or wiring change.
- Bench tested on actual hardware: We ran the pack through full discharge cycles under simulated blade-motor load. The BMS held cutoff thresholds correctly under both normal-grass and surge-load conditions, and the protection circuit tripped as expected when we pushed it into an intentional overload.
- Cold-weather start tip: Before the first mow of the season, bring the battery indoors overnight if temperatures are below 10°C. Cold Li-ion cells have higher internal resistance, and the blade motor's inrush current can trip the BMS on a cold pack before it ever cuts a blade of grass.
BMS cutoff under thick grass or wet-lawn blade load
The blade motor on the i70 series draws a sharp inrush current each time it enters dense or wet grass. If the pack's state of charge is already low, that surge can push cell voltage momentarily below the BMS cutoff threshold. The mower shuts off as a protection response — not a battery fault. Recharge the pack to above 50% before tackling heavy growth, and the BMS will handle normal surge loads without cutting out.
Charger shows fault light after mower sat unused all winter
Li-ion cells self-discharge slowly over months in storage. If the pack drops below roughly 2.5V per cell during winter, most chargers will refuse to accept it and flag a fault. This is a safety lockout, not a dead pack. To recover it, some chargers have a recovery or "boost" mode — hold the mode button for five seconds or check your charger manual for the exact step. If voltage across the pack reads above 18V total, the cells are recoverable; below that, the pack should be recycled.

Frequently Asked Questions
My Wiper i70 cuts out halfway through a row then starts working again after a minute — is the battery faulty?
This is thermal protection activating, not a faulty cell. The blade motor heats the pack during sustained heavy cutting, and the BMS shuts output to protect the cells when internal temperature hits its limit. Let the mower sit for five minutes with the battery still fitted — the BMS re-enables output once the pack cools. If it happens every row, check that the blade isn't clogged with wet clippings, which forces the motor to work harder and generates more heat.
The new battery feels noticeably warmer than the old one after a mow — should I be worried?
Warmth on a new pack during the first few cycles is normal. Fresh cells have slightly higher internal resistance before they are conditioned, which produces more heat during charge and discharge. This settles after approximately five full charge/discharge cycles. If the pack is too hot to hold comfortably after a normal mow beyond cycle five, stop using it and check that the battery bay contacts are clean and seating fully.
The charger accepted the pack fine, but the mower seems to lose power faster in cold spring mornings compared to the same charge level in summer — what's happening?
Li-ion cells lose usable capacity below 10°C because cold temperatures increase internal resistance and reduce how much energy the cells can deliver per discharge. This is a chemistry behaviour, not a defect in the pack. The capacity returns to normal once the battery warms up during use or is brought to ambient temperature. Charge and store the pack indoors before a cold-morning mow to start with cells closer to room temperature.
