in 2013 I bought this 60-LED solar-recharge security light on Amazon. This winter it failed and I took it down to see if it was the battery or not. It did appear to be the battery but I was unable to locate the exact replacement, a welded pack of five 1.5 volt AAs with an aggregate output listed at 6v on the battery wrap itself.

I thought I had found the correct replacement at Home Depot for about $15, a special-order item, but the unit that arrived appeared to be wired backward, either a manufacturing flaw or simply a battery with reversed polarity. I was kinda grumpy about a $15 battery anyway and just returned it.

Once I had determined that the battery was dead I pulled the wiring harness off and experimentally attached it to a 9v battery, and the light illuminated very brightly. What I don’t know is how many illumination cycles the battery might support, and of course finding a rechargeable battery would be even more preferable – the solar array is still producing juice without difficulty.

UPDATE: Sunforceproducts.com sells the part for $10, fee shipping. Ordered.
