MacBook Battery A1953 - OEM Quality Specifications
Engineered For Macbook Pro 15‑inch A1990 (2018–2019), The Macbook Battery A1953 - Oem Quality delivers stable runtime and reliable calibration that technicians can trust on the bench. Rated At 11.4 v and 7336 mah (83.6 wh), The pack uses a 6‑cell lithium‑polymer layout with balanced discharge to match the original energy profile and sleep behavior. Each unit is assembled with a bms for accurate fuel gauging, over‑charge, over‑discharge, over‑current, and short‑circuit protection. The chemistry and protection stack are tuned for low ripple under high load, which keeps throttling events to a minimum during stress tests.
Cycle Life Targets 1000 charge cycles under normal operation, and cells ship at 30–50% state of charge for safe storage. The pack is un38.3, ce, and rohs compliant for cross‑border shipping in europe. Typical standby drain aligns with oem behavior to maintain expected hibernation time on macos mojave through sonoma. The adhesive system is low‑residue and heat tolerant to simplify removal on future service intervals.
Compatible Models And Part Details
Designed For Macbook Pro 15‑inch With Touch Bar model a1990 only, Covering emc 3215 and emc 3359 production runs. The oem reference on the assembly is a1953, And the energy rating matches the factory 83.6 wh specification used on 2018 and 2019 boards. Use This pack as a direct replacement when coconutbattery, system information, or apple diagnostics show high cycle count, service recommended status, or abnormal deviation in the dc in amperage curve.
Connector Geometry Matches the original board interface and clears the speaker enclosures and trackpad frame without shimming. The cell layout preserves the stepped profile to sit level against the top case, Preventing pressure points on the underside of the trackpad. No firmware pairing is required, So the battery is recognized immediately after reconnect and smc initialization on first boot.</>
Installation Notes For Repair Shops
Disconnect Power, Remove the pentalobe bottom screws, And isolate the battery before unplugging any flex. Use Controlled heat or adhesive remover to release the cell blocks from the top case, Working from the outer banks toward the center to avoid prying against the logic board. Clean The bonding surfaces with isopropyl alcohol, Route the harness along the original channels, Seat all six pads, And apply firm even pressure for 60 seconds before reassembly. Refit The bottom case, Reconnect power And perform a battery calibration: charge to 100%, leave on charger for two hours, discharge to 5–10%, let the unit rest for two hours, then recharge to 100%.
Allow At Least 3–5 full cycles for the fuel gauge to converge after install. If You encounter erratic percentage reporting, Run smc and nvram resets and confirm no third‑party kernel extensions are influencing sleep. Replace Any swollen pack immediately and recycle according to local wEEE guidelines. Typical Install Time is 45–75 minutes for experienced technicians with proper adhesive tools and speaker removal steps.
Why It Fits Refurbishment And Fleet Work
Shops Get Consistent runtimes that meet macbook pro workloads like video encoding, xcode builds, and multi‑tab browsing without sudden drop‑offs near 20%. Bulk Orders Ship with traceable lot numbers and date codes, Helping you track rma windows and shelf life. Each Unit is sealed in anti‑static packaging with protective trays to prevent cell flex in transit. Labels Include voltage, capacity, and compliance marks for warehouse checks.
Use It For High‑volume top case repairs, corporate fleet refresh, or post‑diagnostic replacements when dc in and logic board rails test within spec. Pair The Macbook Battery A1953 - Oem Quality with new bottom screws and fresh speaker gaskets to minimize callbacks, And keep adhesive cards, isopropyl, and a low‑heat station ready to streamline repeat jobs.
