Sanyo ES88 Replacement Battery 6V 2100mAh Ni-MH

Up to 20% off
New arrival
From $35.99 USD $44.99
Shipping calculated at checkout.
Fits Sanyo ES88, EX30P, EX70P, FA114 and 53 additional camera models; replaces OEM CS-NP55 battery pack directly.
6V Ni-MH chemistry at 2100mAh delivers 12.6Wh for standard shooting cycles on compact digital cameras without external power.
Connector slides into camera battery bay with positive contact first; locking tab seats flush against chamber wall when fully inserted.
We bench-tested this cell on a Sanyo ES88 body—BMS accepted the pack on first insertion with no rejection codes or false low-battery indicators.
On first use, run one complete charge cycle in the camera body before extended shooting; some Sanyo models need this initial cycle to calibrate remaining-battery display accuracy.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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

🔹 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.

Sanyo ES88 / EX30P / EX70P Series — 6V Ni-MH 2100mAh Replacement Battery

This is a 6V Ni-MH replacement battery rated at 2100mAh (12.6Wh) for Sanyo cameras including the ES88, EX30P, EX70P, and FA114. It replaces the original cell when the OEM battery no longer holds a usable charge or fails outright. The pack matches the original's voltage and form factor to fit the camera body without modification.

  • ES88 / EX30P / EX70P compatibility: These Sanyo camera models share the same battery bay dimensions and 6V power rail. The BMS in each body reads cell voltage at startup, so matching voltage matters — a mismatched cell trips the no-battery indicator before the camera finishes booting.
  • Bench tested on actual hardware: We cycled this pack through charge and discharge on the bench. The BMS handshake completed cleanly across multiple power-on cycles, and the protection circuit tripped correctly at low-voltage cutoff without requiring a manual reset.
  • First-cycle charge via OEM charger: Ni-MH cells in this voltage range can read incorrectly on the camera's battery-remaining display until the BMS has mapped the discharge curve. Run one full charge cycle in the OEM charger before shooting — this lets the camera body calibrate its indicator to the new cell's actual discharge profile.

Why the ES88 shows a dead battery indicator on a partially charged replacement cell

The ES88 maps its battery indicator against the original cell's discharge curve. A new Ni-MH replacement has a flatter discharge curve than a worn OEM cell, so the camera's voltage threshold logic can misread remaining capacity and flag low battery early. This is a calibration issue, not a fault in the replacement cell. Running one full charge-discharge cycle resets the reference points the BMS uses to display remaining charge accurately.

Flash not fully recycling between shots

If the flash fires but takes noticeably longer to recycle on subsequent shots, the capacitor recharge current is outpacing what the cell can supply at that moment in the discharge curve. This typically appears when the pack is below 5.4V under load — near end of charge rather than a defective cell. Check the battery indicator before a shoot and recharge when it hits the first warning threshold. A fully charged pack at 6V nominal handles flash capacitor recharge without noticeable lag.

Frequently Asked Questions

My Sanyo ES88 shows "no battery" the first time I put in this replacement — is the cell dead?

It is not dead. The ES88's BMS runs a voltage authentication check at startup and sometimes rejects a new cell that has partially self-discharged in storage. Place the battery in the OEM charger, run a full charge cycle, then reinsert it. The camera should recognise it cleanly once the cell sits above the startup threshold voltage of approximately 5.8V.

The battery percentage on my EX70P jumps around — it shows 80%, drops to 20%, then jumps back up. What's happening?

The EX70P maps its percentage display against voltage thresholds calibrated to the original OEM discharge curve. A fresh Ni-MH replacement has a flatter curve, so the camera's indicator logic loses its reference points mid-discharge and reads erratically. Run two full charge-discharge cycles through the OEM charger. After that, the camera body re-maps the thresholds to the new cell's actual curve and the percentage display stabilises.

My shot count dropped noticeably compared to what I got from the original battery — why?

Flash recycling, continuous autofocus, and the optical viewfinder all pull current beyond what a basic shot count estimate accounts for. If you shoot with flash enabled on every frame, expect significantly fewer shots than the rated capacity suggests — the capacitor recharge draw is the biggest variable. A new Ni-MH cell also operates slightly below its rated capacity for the first few cycles before the plates condition fully. Shot count typically improves after three to five full charge-discharge cycles.
